MIL-HDBK-17, also known as the Composite Materials Handbook, is the primary and authori-tative source for statistically based characterization data of current and emerging composite materials, reflecting the best available data and technology for testing and analysis, and includingdata development and usage guidelines. The handbook provides the information and guidancenecessary to design and fabricate end items from composite materials. Its primary purpose is thestandardization of engineering data development methodologies related to testing, data reduction,and reporting of property data for current and emerging composite materials.

In support of this objective, the handbook includes composite materials properties that meetspecific data requirements. The handbook therefore constitutes an overview of composites tech-nology and engineering, an area that is advancing and changing rapidly. As a result, the document is constantly changing as sections are added or modified to reflect advances in the state-of-the-art.

The overall effort is co-chaired by Gary Hagnauer, U. S. Army Research Laboratory (ARL), andJoseph Soderquist, Federal Aviation Administration (FAA).

“The application scope of MIL-HDBK-17 for polymer-matrix composites is actively expandingfrom the previous focus on aircraft applications,” says Hagnauer. “This expansion in focus is essen-

Army, Navy, Air Force Announce New Materials Facilities

The U.S. Army, Navy and Air Force have each announced the creation of a new materials facility.The Rodman Materials Research Laboratory, the Ship Materials Technology Center, and theAircraft Coatings Test Facility provide modern materials research and development capabilitiesresponding to the special needs of the sponsoring services.

The Army’s Rodman Materials Research Laboratory is located at the Aberdeen Proving Ground,Maryland, and is a unit of the Army Research Laboratory (ARL). Rodman personnel conductresearch on advanced materials such as polymers, specialty organic materials, elastomers, com-posites, and high performance ceramics and metals for individual soldiers’ protection, armoredvehicle protection, and anti-armor applications.

The 290,000 square foot (6.5 acre) facility was dedicated on July 29, 1997. It is named in memory of Brigadier General Thomas J. Rodman (1815-1871), who was commander of the Watertown, MA Arsenal, and patented processes which resulted in significant increases in themuzzle velocity of cannon shells and an order of magnitude increase in cannon life.

For more information, contact ARL Public Affairs Office, Aberdeen Proving Ground, MD21005-5066. Tel: (410) 278-5964. Fax: (410) 278-2771.

The Nav y ’s Ship Mate rials Te chnology Center (SMTC ) is located at the Naval Surface WarfareCenter, Carderock Division, in West Bethesda, Maryland. The center’s responsibilities includedeveloping advanced materials, engineering mechanics, chemical formulation, testing and charac-terization of metallic and nonmetallic materials, and prototype production and testing of ship system components.

The 150,000 square foot facility was officially opened on June 18, 1997, marking the com-pletion of a transition of personnel from their previous facility in Annapolis. The 200 centeremployees are now part of 1,700 Carderock Division employees at the West Bethesda location.

MIL-HDBK-17:Expanding to New Application Areas

The AMPTIAC Newsletter, Volume 1, Number 32

AMPTIAC People

Meet Dr. Carlos Sanday, the Associate ContractingOfficer’s Technical Representative (COTR) to AMP-T I AC for Ceramics and Ceramic CompositeMaterials. In this capacity, he provides direction toAMPTIAC for their efforts in collecting and dissemi-nating information in this materials area.

Dr. Sanday is currently the Manager of thePrograms Office in the Materials Science andTechnology Division at the Naval Research Laboratoryin Washington DC. Drawing on the capabilities of hisdivision, Dr. Sanday plays a vital role in coordinatingand monitoring inter-branch programs that span awide range of materials and processes.

Born in Buenos Aires, Argentina, Dr. Sanday com-pleted his undergraduate work in Mathematics atColumbia University. He then moved to CarnegieMellon University where he completed his graduatetraining in engineering, focussing on mechanics for hisdoctoral dissertation. Prior to joining the Na va lResearch Laboratory, Dr. Sanday spent several years inthe private sector, having begun his professional careerat US St e e l’s Edgar C. Bain Laboratory forFundamental Research. He was the Head of theComposites and Ceramics Branch at the MaterialsScience and Technology Division of the Na va lResearch Laboratory for 18 years during which timehe directed numerous research programs in bothmonolithic and reinforced ceramic materials. He hasbeen in his present position since 1994.

Dr. Sanday believes that the significant problems

and issues in ceramics and ceramic composites havenot changed much since the time they were first con-sidered for application. Brittleness and joining remainthe major obstacles to the structural application ofthese materials. Therefore, the significant researchareas also have not changed much with time. He is ofthe opinion that any major structural application willhinge on the resolution of the twin issues of brittlenessand joining. In contrast to this scenario, there havebeen successful developments in the field of specialpurpose ceramics in non-structural applications as forexample, electronic ceramics.

With reference to the role of AMPTIAC in theceramics and ceramic composites community, Dr.Sanday considers its pivotal function to be that ofkeeping the DoD community abreast of the develop-ments in this area, in addition to compiling and disseminating specific data and information that is rel-evant to the user. He is appreciative of the work that ispresently being performed by AMPTIAC and suggeststhat the generation of specifications for processing andtesting of both structural and non-structural ceramicsmay be a possible thrust area for the AMPTIAC in thefuture.

tial to the handbook’s application to a broad-er user community. The standardization ofmaterial characterization and designapproaches will facilitate the application ofcomposites to ground and marine struc-tures.”

“The handbook will remain the defini-t i ve international source of data anddesign guidance for certification of com-m e rcial aircraft,” says So d e rquist. “At thesame time, expansion of its scope is essen-tial if it is to meet the needs associated with

the ever-expanding use of com-posites in all applications.”

Ef f o rts that are con-tributing to this expansion offocus include the Sp e c i a l i ze dData De velopment Wo rk i n gGro u p, the Building Bl o c kAp p roach Committee, anA r m y - Navy task group thatre p o rts to the handbookchairs, new activity in theUn i versity of De l a w a reComposite Materials Re s e a rc h(CMR) program, and the hand-

book secre t a r i a t’s contract with Ma t e r i a l sSciences Corporation (MSC). Pre v i o u s l yu n a d d ressed areas currently under considera-tion include ground vehicles, marine stru c-t u res, general aviation, and space applications.“We’re pushing the envelope on the tradition-al way of doing business and being ve ry pro a c-t i ve in negotiating with a variety of agencies,”says Walt Rosen of MSC, “including industry,NASA, DOE, the Na v y, and NIST. ”

The Specialized Data Development work-ing group is chaired by Gene Camponeschi( Na val Su rface Wa rf a re Center), Da n aGranville (ARL), and Terry Vandiver (U. S.Army Aviation and Missile Command). Theworking group was formed with the specificobjective of incorporating data requirements,test methods, and materials data appropriatefor new applications in the handbook.

A step in the expansion of MIL-HDBK-17 to these new application areas is thedevelopment of a new chapter on a buildingblock approach for each family of applica-tions. The Building Block Subcommittee,led by Bruce Fink, ARL, reports to the MIL-HDBK-17 Guidelines working group. Finkpoints out that the building block approach

is a good starting point for expansion effortsbecause it constitutes the foundation of vir-tually any type of testing plan.

The Army-Navy task group works off-line from the main MIL-HDBK-17 meet-ings and re p o rts to the handbook chairs.“ Our overall goal is to increase confidencein the use of composites,” says NSWC ’sCamponeschi. “One critical element in thisis having access to standardized data andguidelines.”

The assessment task under the ARL-Un i versity of De l a w a re CMR pro g r a m ,headed by Crystal Newton and Ja c kGillespie, is addressing requirements for theapplication of composite materials to non-aircraft military uses. “For each applicationsarea, the effort that is expended on test plandevelopment and material characterizationtesting can be significantly reduced by devel-oping a standard approach for test plans fornew materials and a standardized and acces-sible database combined with procedures fora p p ropriate and acceptable usage,” saysGillespie.

Members of the polymer-, metal-, andceramic-matrix composites communities areencouraged to become actively involved inthe development of the handbook by attend-ing the semi-annual coordination gro u pmeetings on a regular basis. “The broader therange of participants, the better and moreuseful the handbook will become,” MSC’sGerry Flanagan points out. “T h e re are nomembership dues or fees and no re q u i re-ments for becoming a participating mem-ber of any working gro u p. Your contribu-tion will help to produce a CompositeMaterials Handbook that is a va l u a b l ere s o u rce for the entire composites commu-n i t y.” To become invo l ved in theComposite Materials Ha n d b o o kC o o rdination Groups, please contactFlanagan by…

Engineers have had to apply a variety of disciplines to thedesign of spacecraft and satellites to control their tempera-tures outside the atmosphere. The objective of thermal designis to ensure that spacecraft operate within the temperatureranges prescribed by the limitations of the vehicles’ materials,components, and occupants.

Two fundamentally different techniques are used to regu-late the temperature of space vehicles – active and passive.Active control employs electric heaters and/or variable-posi-tion shutters that vary the areas of specific reflective surfacesexposed to incident radiation. Passive control employs onlythe optical characteristics of the vehicle’s fixed surface finish-es to achieve a balance of energy absorption, reflection, andemission. The later method is more desirable in that it obvi-ates extra equipment and feedback mechanisms.

Wo rking with the National Ae ronautics Sp a c eAdministration in the early 60s, IIT Re s e a rch In s t i t u t e(IITRI) developed two coatings widely used in the Ge m i n iand Apollo programs to achieve passive contro l .1 These coat-ings, designated Z93 and S13G, employ pigments which serve

as good solar reflectors and infrare demitters, there by providing the heatdissipation mechanism vital to va r i-ous spacecraft areas and components.Both pigments and binders we reselected and pre p a red to retain theirp ro p e rties under the seve re radiationand vacuum conditions encountere doutside the atmosphere. Mo re ove r,the coatings we re developed so thatthe pigment and binder enhance onea n o t h e r’s stabilities.

Radiation Variables

The temperature of a spacecraft at any time is that at whichthe absorbed radiation, the energy dissipated by its internalsystems, and the energy it emits or radiates are in balance. Asany parameter varies, a compensating temperature changeaffects a new equilibrium. Discounting, for a moment, theheat generated and dissipated by internal systems and occu-pants, the elements affecting the thermal condition of aspacecraft are the sun’s radiation, the earth’s reflection, andthe earth’s infrared emission.

Evaluation of the energy exchange between a satellite inspace and the earth and sun leads to a simplified radiant-heat-transfer analysis. Such an analysis shows that the temperatureof any body in space varies as the fourth root of the ratio of solar absorptance to infrared emittance (αS/E)of the surfaces involved. Vehicle temperature can be plottedas a function of this ratio for any number of fixed positionsin space.

Coating Selection

In reality, a typical earth-orbiting satellite exhibits a constant-ly changing spatial attitude. It tumbles; it travels in and out

of the earth’s shadow; it possesses internal heat dissipationcaused by man work, batteries, fuel cells, or solar cells. Theg e o m e t ry, color, and finish of surfaces determine solarreflectance and infrared emittance, and thereby introducevariations which also affect local and overall energy exchange.It is these surface characteristics that offer the designer thegreatest selections with which to achieve passive temperaturecontrol.

While a variety of surface materials, finishes, and coatingsare available, those that can realistically be used on spacecraftare limited by various constraints. The need for stability inthe space environment severely limits the number of usefulcoatings. Other restrictions are related to less obvious, butequally limiting, aspects. For example, if a coating requires“baking” at 500°F to cure, and can only be applied after elec-tronic subassemblies have been added, while the upper tem-perature limit of the electronics is 250°F, it is not a practicalcoating for that particular application. Other criteriaemployed in choosing thermal-control surfaces are: pre-launch environment and cleanability; ascent environment;radiant interactions of thermal-control surfaces; ability torepair a coating to fully restore its optical properties; and ofresponse to thermal and space simulation.

A popular misconception is that polished metal surfacesprovide the best heat dissipation surface. A polished metalsurface, e.g. aluminum foil, having a solar absorptance of0.15 and an infrared emittance of 0.03 results in a body sur-face having a αS/E of 5. In an average spatial attitude thebody would maintain an equilibrium temperature of 150°C.If on the other hand, the body were painted black (αS/E≈1),it would maintain a temperature of about 25°C. Althoughthe foil reflects more energy than the blank paint, it is a poor emitter, and therefore assumes a considerably higher temper-ature than the black paint in order to reradiate the energy itreceives.

If the same body were painted white (αS/E ≈0.2) its tem-perature would be about -50°C. Of the available materials,therefore, white paints possessing low αS/E ratios provide thebest possible heat dissipation mechanisms. As a result they areparticularly useful for vehicles and components that generateheat internally.

White paints are also attractive spacecraft coatings becausethey are easy to apply and clean. Many, in fact, are air cured.The white paints used for space application are pigmented sil-icate and polymeric coatings, not unlike conventional housepaints. They differ, however, in two important characteristics.Formulated for appeal and “hiding power,” conventionalpaints do not have the reflectance that could be achieved ifthe former qualities were given lower priority. Secondly,house paints are relatively unstable in a high radiation/vacu-um environment and would not survive long in space. Manycommercial paints were tried during the course of the U.S.space program, and indeed most of them deteriorated quick-ly in space, actually turning brown and severely reducingreflectivity.

Spacecraft Performance

Hi s t o r i c a l l y, IITRI’s inorganic Z93 and organicS13G have been used extensively on a number ofd i f f e rent missions from the early Gemini (Z93) toboth of the recent Mars Pathfinder and MarsGlobal Surveyor spacecraft. Still another inorganicformulation, YB-71, helps to maintain a desiredcryogenic environment on the Defense SatelliteProgram spacecraft which are in geosynchronousorbit.

A particularly valuable space-based materialsexperiment was the Long Duration Ex p o s u reFacility (LDEF) in which a variety of materials weresubjected to about 60 months of exposure in near-earth orbit. Two materials which were shown to beoptically stable from data obtained during the first12 months of exposure as well as from measure-ments of the retrieved samples were the inorganicZ93 and YB-71, silicate-based paints pigmentedwith zinc oxide and with zinc orthotitanate.2 TheZ93P has been designated for use on large surface

areas of Space Station radiators based in large mea-sure on the LDEF results.

As space mission re q u i rements become morestringent and longer performance is needed,demands for more diversified and “better” coatingswill continue. Materials to enable satellites andspacecraft to function satisfactorily will need to bedeveloped. Good compatibility of coatings to newlyemerging lightweight organic matrix composites,electrically conductivity issues, and environmentallyfriendly organic formulations are just some of thesegoals.

Expected to be completed in February, 1998 is an Aircraft Coatings Test Facility being constructed bythe Materials Directorate of the Air Force’s Wright Laboratory at Wright-Patterson AFB, Ohio. Its corewill be a paint booth which will be able to replicate temperatures from 40 to 110 degrees (F) and humid-ity from 10 to 90 percent. Using information generated from operational environment simulation, thefacility will be able to provide recommendations on top coats of paint suitable for specific missions, aswell as primers and cleaners for the top coat. In addition, the facility will identify equipment and process-es necessary for treating surfaces and stripping paint. A primary mission will be the development and inte-gration of environmentally acceptable materials and processes for coating aircraft.

When completed, the facility will be operated by a Coatings Technology Integration Office (CTIO)representing the interests of the five Air Force Logistics Centers and the Air Force Major Commands.
