Applications in aerospace, recreational and high-tech marineform the basis of the Australian Advanced Composites (AC)industry. Not withstanding some early developments ininfrastructure, which may develop a new sector?

A recent survey of the members of the Composites Institute ofAustralia (CIA) identified approximately one fifth of its membersused or had the capabilities to process advanced compositematerials. Many of these were small companies supplying nichemarkets or larger companies that were project driven (i.e. theyprocess advanced composites when circumstances demand).

CIA Survey SummaryOf 278 CIA member companies, 177 completed the survey asfar as possible. Of those, 65 do not manufacture – 112manufactures surveyed.

This seems to reflect that many of the Australian compositemanufactures are adaptable in their abilities to process variousmaterials and don't just specialised in singular techniques.Withthe bulk of the industry using polyester resins, open mouldingand spray up, it is interesting that bagging and autoclavecapabilities are significant bearing in mind that no largeaerospace companies were in the survey sample.

When asked what were the trends in AC's in Australia, twomajor material suppliers believed that change was occurring inhow these materials were processed, not changes in thematerials themselves. One example given was a movementtowards infusion system rather than using pre-preged materials.It was felt that some leading-edge yacht manufactures weretrying to avoid interlayer adhesion problems that were thoughtto be behind some recent failures. Another supplier felt therewas a movement from open molding to pre-preg products. ZPreg and SPRINT were also given as examples of changes inprocessing technology. Sydney's leading yacht manufacturerMcConaghy's agreed that changes in processing along withchanges in design tools were driving the high performance yachtmarket. Once described as standing under the shower tearingup $100 bills today's ocean racers are still doing that, but areriding hulls virtually designed and built in an environment ofchange, increasing sophistication and cost. In the past three yearseach major project at McConaghy's has involved changes inmaterials, processing and design; they are currently using SPSystems SPRINT material to produce another high-end oceanracing yacht. Having built 4 out of the first 5 boats to finish in

this year’s Fastnet race, they have shown that things are far fromconstant at the elite end of yacht design.

90ft long, 135ft high all carbon fibreAlfa Romeo, built by McConaghy Boats– Moan Vale, Sydney Australia is aworld-beating leader being followedby their current project and otherslike the new 98ft Wild Thing out ofHart Marine Mornington, MelbourneAustralia.These boats are definitelylarge elite uses of advancedcomposite materials.

The premier motor sport class in Australia,V8 super cars hasbeen on the fringe of AC composite utilisation for a number ofyears with teams like Holden Racing and Ford producing thefascias, wings, IP's and trim to lighten these super modifiedsedans. But full on adoption has been limited by class regulations.Never-the-less over the past 5 years we have seen increasingutilisation of advanced composites at all levels of motor sportwith a number of small companies setting up to producecomponents for the race track and street car mod's.

Companies such as LSM in Toowoomba run a number ofautoclaves and although they supply other markets it's safe tosay they are based primarily in motor sport. As conventionalcomposites begin to gain ground in mainstream automotiveapplications the design studios and advanced engineeringdepartments are also adopting advanced composite materialsfor prototyping and prove out applications.

Composites are becoming a viable alternative in nicheapplications. GM Holden is about to release their new all-wheelderive sports utility with a composite roof. As the Australianautomotive industry reaches the critical mass that allows it toutilise different materials we see increased usage of composites.The Australian car industry has a long way to go to catch up toU.S. and European usage, some predict they will jump thethermosets and go straight to the new generation of thermoreinforced plastics.The major Australian car companies tend towait for technology and materials to be proven elsewhere andthen cherry pick to suite their needs. Some small amounts ofadvanced composites are used in custom sports cars but in themain these vehicles tend to run conventional high quality FRPlaminates and there is no dedicated large high performancevehicle manufacturer in Australia.

V8 super cars run ACfronts, rears, fascias,interiors and wings andare the glamour class inAustralian motor sport.Composite Institutemember Holden Racingare processing in-houseautoclave capabilities andlooking to expand their composite division to supply their sistercompany Holden Special Vehicles with AC enhancement andperformance improving components.

surfaces and major structural assemblies are produced for mostof the world's large commercial and military aircraft. ‘Hawkers’has major contracts with the world's leading aircraftmanufactures such as Airbus, Boeing Commercial Airplane,Boeing Integrated Defence Systems, Lockheed Martin,Bombardier and BAE SYSTEMS.

Most of Hawker de Havilland's Research and Developmentexpenditure goes towards developing techniques and processesto design, cure and assemble composite aerostructures.Thisprovides an idea of the growing importance composites play inaerospace manufacturing.The development of efficient newmanufacturing technologies for aerospace applications is themajor thrust of Hawker de Havilland and their Australianresearch partners. In addition to dedicated internal researchprograms, research is also conducted in collaboration with theCooperative Research Centre for Advanced CompositeStructures (CRC-ACS) where Hawker de Havilland is theprincipal aerospace industry participant, the CooperativeResearch Centre for Intelligent Manufacturing SystemsTechnologies (CRC-IMST) and a number of AustralianUniversities.

‘Hawkers’ core capability is in advanced composites.They havecomprehensive in-house capabilities for composite and metal-to-metal bonding within a world class facility. One autoclaveused for curing composite structures is the largest in thesouthern hemisphere -– allowing the Company to cure largecomposite structures.

The aerospace industry in Australia is often regarded as a standalone entity and it is. But importantly it requires and drives highstandards that can flow to the rest of the industry. It may also inpart account for the significant number of CIA manufacturersthat have an understanding of AC materials and processing. Aswith the other applications discussed it is elite use.

An outsider might think that these specialised elite applicationscould be prone to falling over. However they have inherentadvantages which give them the ability to ‘keep on standing’. Asdid Steve Bradbury in his gold medal win in the1000 metres fasttrack speed skating at the Atlanta Olympics February 2002.When he won gold, he was wearing his own boots made by hisunique niche company the Revolutionary Boot Company (RBC).With his partner Clint Jensen, they have become part of theAustralian AC industry.

The Revolutionary BootCompany can tailor the shape ofthe boot to match the skater’sfoot contours exactly, that enablesa superb fit which in turnprovides direct power transfer

from the skater to the skate (i.e. speed). By altering the lay-up,the boots stiffness can be altered to suit the individual skater.The mounting points for skate attachments are plastic injectedmoulded discs which are co-cured in the laminate. RBC –another successful niche elite application – but what are they

doing as the world’s top ice-skate manufacturer in sunnyQueensland?

One common thread has been apparent throughout all theapplications mentioned, it is the need for speed. It is often linkedwith success as well as enabling success.The Australian advancedcomposite industry is a very successful niche in the Australiancomposites industry.The general industry is estimated to begrowing at over 5% p.a. – the advanced end may be more orless, we don't have the figures.

Released with this issue of the Composites Institute of Australianewsletter is the Model Environmental Management Plan for theComposites Industry. It is a product of a partnership between theNSW Chapter of the CIA and the NSW Department ofEnvironment and Conservation (formerly the EPA) CleanerIndustries Unit. Under a grant from the DEC IndustrialPartnership Program the Model EMP has been developed aswalk-through document to aid composites fabricators to developsite-specific environmental management plans for their sites.

The philosophy behind the Model EMP is to go beyondcompliance with regulatory requirements and adopt industry bestpractice that will reduce costs and lessen environmental impacts.

The previous booklet, Environmental Information for the CompositesIndustry in the Solutions to Pollution Series, was aimed at assistingfabricators and regulators with compliance issues. It is stillavailable from the NSW DEC on their website atwww.epa.nsw.gov.au/small_business/composites.htm along withsimilar booklets for other industries.

The Model EMP has been published in booklet form and on aCD.The CD contains the Model EMP document in PDF format,worksheets and Case Studies.The worksheets are in Wordformat and can be used interactively.The case studies illustratethe use of the worksheets and demonstrate cost savings that canbe made.The CD should start up automatically, however, if itdoes not, the document files can be accessed through WindowsExplorer. At a later date the Model EMP will be accessible on theCIA website.

The booklet and CD are being distributed to the NSWmembers of the CIA.The NSW Department of TAFE has alsodeveloped a resource module for the EMP to be included in theRubber and Plastics Technicians Certificate.

An innovative fibre composites truss structure and a range ofother fibre composite technologies will enable an estimated20,000 Brisbane residents per day to literally walk on water.

The new showcase floating walkway of Brisbane's RiverWalkproject near New Farm will allow the people of Brisbane tostroll or cycle along one of the most scenic reaches of the river.Executive Director of the University of Southern Queensland'sFibre Composites Design and Development (FCDD) Centre ofExcellence, Professor Gerard Van Erp, said the construction ofthe RiverWalk has pushed the boundaries of structuraltechnology.The 850 metre walkway on the river at New Farm isthe centrepiece of the 30km-long RiverWalk project.

"When engineerslooked to provideaccess from thewaterfront onto thefloating walkway ofthe RiverWalk projectat New Farm, theextremely high

dynamic loads and harsh environment made traditional designsolutions a prohibitive option," Professor Van Erp said.

"We needed to provide an extremely durable and high capacitysolution to a difficult engineering problem.The 18 metre-longfibre composite truss stabilises the downstream end of thefloating walkway and will allow safe access on and off the mainwalkway during peak usage of the RiverWalk. It provides anextremely durable and high capacity solution to a difficultengineering problem."

He said the truss was partially submerged in salt water andsubject to severe dynamic loading so the design posed significantproblems for traditional construction materials. Estimates on analternative stainless steel solution were nearly three times theprice of the new composites truss.

"Because of its light weight, the truss also offers significantbenefits in terms of construction time with assembly of thestructure taking only two hours at FCDD on the USQ campusin Toowoomba.

"This project represents a major step forward in engineeringtechnology. It is the first fibre composite truss in the world that iscapable of carrying these high loads in such a severeenvironment.The spin-off effects will be significant and are likelyto change the way structures in, or near salt water, will be builtin the future. Due to the high durability of composites there willbe a major reduction in maintenance costs which will result inconsiderable savings for the community for many years tocome," Professor Van Erp said.

In addition to the truss, FCDD has also provided a range ofother new structural fibre composite technologies for thefloating walkway.These have all been based on FCDD's noveldesign solutions which use composite materials to addressspecific shortcomings of traditional structural materials.

"The RiverWalk will cater for jogging, cycling, walking andrecreation and will join the people of Brisbane and the rivertogether," Professor Van Erp said.

Designing with Composite MaterialsPart 2: Materials Selection and ProcessThe selection of materials to be used in the composite, i.e. thefibre and the resin system, and the manufacturing process toform the structure are most critical in the development of thefinal composite engineering and physical material properties.Thefibres generally hold the key to the majority of the properties.There is a wide range of fibres to select from, but generally, theend result comes down to cost, weight and performance.Table 1 shows the general stress/strain relationship betweenseveral common fibre types.The fibres also come in a numberof forms, i.e. continuous unidirectional, woven cloth or shortfibre mat. Each form represents a different level of achievableproperties.The most efficient fibre form (weight vs.performance) is the continuous unidirectional, then followed bywoven cloth and last the short fibre mat.The effect of fibreform is illustrated through the achievable fibre volume ratio andrelative performance, see below.

The resin system is used to bind, protect and assist the fibres

with load transfer. Based on a simple micromechanics rule ofmixtures approach the two major properties (axial strength andstiffness) of the composite structure are proportional to thefibre properties and the fibre volume ratio.The typical aim is tohave both a high fibre stiffness and fibre volume ratio forstructural efficiency. During the process of composite structurefabrication, the fibre volume ratio is dictated by the removal ofexcess resin. As the fibre volume ratio changes there is aproportional change in the mechanical and physical propertiesof the composite structure.Thus, to achieve a specificengineering deflection (stiffness dominated) or load bearingcapacity (structural strength) for example, a reduced relativestiffness due to fibre form, or a reduced strength because of alow fibre volume ratio will require a thicker section to be made.Noting that the higher performance fibres are generally lighterthan the matrix, then combined with an overall larger cross-section dimensions you have a heavier structure.This is alsodirectly related to a higher cost in terms of materials and labour.Cost estimate will be covered in a future article.

The following table clearly shows this effect with stiffnessefficiency.

Stiffness Efficiency Index = Stiffness Index xVfVf (Uniaxial)

Stiffness Maximum Stiffness Index Vf Efficiency Index

Axial 1.00 0.70 1.00

Biaxial 0.50 0.60 0.42

Random (Planar) 0.30 0.35 0.15

Random (3D) 0.12 0.30 0.05

The selection of the manufacturing process, and there areseveral to choose from, will be dependent of equipmentavailability, cost, time, materials selection, product quantity, forexample. However, whatever process is selected, thedevelopment of composite material properties will be based onply or fibre orientation and the fibre volume ratio.

Your choice of fibre type, fibre form, resin system andmanufacturing process will determine the composite materialproperties… as the Knight protecting the Holy Grail said toIndiana Jones, in the movie, The Last Crusade, "choose wisely".

In the next article, we will see how you can determine thenumber of plies required in various orientations to meet thestructural properties of the structure. I also welcome questions,comments and your point of view. Feel free to contact me [email protected]. I may publish your questions andcomments, and my response in future newsletter.

The use of composite structures has become an increasinglyimportant factor in engineering design. Australia has a rapidlydeveloping composite industry which is supported bycommercial, government and university research departments aswell as international collaborations.To enable discussion of ideasand foster developments in the application of compositematerials in engineering structures within Australia, theAustralian Composite Structures Society (ACSS), a TechnicalSociety of Engineers Australia, was established in 1992 with theaim to provide a forum for such activities.

The Objectives of the ACSS:�To act as a learned society, embracing all aspects of

engineering theory and practice, relevant to the structuralapplication of composite materials in Australia

�To promote the wider structural application of compositematerials in the interest of Australian economic development

�To inform its members of local and overseas activities ofscientific and engineering significance in the field of compositestructures

�To provide opportunities for intellectual and fraternalexchange for Society members with a common interest in thedevelopment of composite structures and associatedtechnologies

�To liaise with other scientific and engineering bodies withsimilar aims, and in particular to represent Australia oninternational organisations, such as the InternationalCommittee on Composite Materials

� Application for membership may be made by contacting theMembership Secretary at [email protected].

This Board now holds the future of the CIA in its hands.Thequestion of how to fund and grow the organisation is at a pointthat will determine what form and what type of associationexists in 2004 and onwards.The CIA has been operating withthe assistance of a Technology Diffusion (TDP) grant initially viathe University of South Australia, and now through FlindersUniversity for the past 3 years.

This grant has been a great benefit to our organisation and givenus the opportunity to introduce a number of new initiatives e.g.the new format of Composites Australia, website developmentand the employment of a marketing professional.

However the grant is now drawing to a close and the CIA boardneeds to address how the Institute can be funded in the future.We can build on the gains made with the TDP money or goback to relying on our membership funds and seminar revenue.
