ABSTRACT

Conclusion

References

Simple mixing and hot pressing methods were used to make highstrength and light-weight composite from oil palmempty fruit bunches (OPEFB)

using PVAc as an adhesive and silica nanoparticles as a filler. The mechanical

strength of the composite was examined in term of compressive strength. The

simple mixing method was used to mix composition with PVAc and silica

nanoparticles. Silica nanoparticles were added as filler.

At pressing pressure of 100 MPa, pressing temperature of 300

o

C, andpressing time of 20 minutes, we found compressive strength of 11,35 MPa. Data

analysis of XRD showed that the used silica nanoparticles were in amorphous

phase or had broad pattern. The compressive strength data showed that the

composites were stronger than the composites made by Masturi and

Kumagizuri, and also stronger than the ordinary wood-based composites. Thus,

the composites are feasible to be used to replace wood-based composites,

especially in furnishings.

INTRODUCTION

South Sumatera is one of the three major palm tree producing provinces inIndonesia.

OPEFB is one of oil palm mill residue wastes.

Nanocomposite material consists of two or more organic/inorganic in somecombination form separated at least by a molecule and has at least one-dimensional nano size [3].

The addition of silica nanoparticles will reinforce the mechanical strength of the

composite. s

EXPERIMENTAL

we used OPEFB brought from Tanjung Siapi-api, South Sumatera, Indonesia.LOCATION

The measurement of composite compressive strength was performed using a

Torsee (Tokyo Testing Machine MFG, Ltd.).The size of silica nanoparticles was measured using a scanning electron

microscope (SEM JEOL JSM-6360LA) and its crystallization was determined by X-ray diffraction (XRD).

TOOLS

OPEFB were dried and cut into small pieces.

Polyvinyl acetate (PVAc; FOXTM) was used as an adhesive. In specific mass, it wasdissolved in 8 mL of water and stirred for 10 minutes by using magnetic stirrer.

OPEFB was then put into the PVAc solution and mixed. The mixture was then putinto a cylindrical mold and hot-pressed at varied pressing temperature, time, andpressures.

The fabricated samples had diameter of 26 mm and height of 25 27 mm

CONCLUSION

1 We succeeded in making composites with simple mixing and hot pressing methods by using OPEFB,

PVAc, and silica nanoparticles.

2

Mass fraction of PVAc/OPEFB of 13 : 2 has compressive strength of 82,88 MPa.

Composite with high compressive strength of 100,39 MPa was obtained using silica nanoparticles ata pressing pressure of 80 MPa, pressing temperature of 150 oC, and pressing time of 20 minutes.When the pressing pressure of 100 MPa was applied, the compressing strength increased untilreached a saturation value at 115,35 MPa. The same condition occured by varying pressing time.

3

These results are better than those of Masturiof home-waste composite[7]in which its compressivestrength is 84,37MPa and also better than Kumagai and Sasaki of rice husk composite reached 55,7MPa[10].

Thus, the composite is feasible to replace wood-based composite, especially in furnishing.
