Abstract :
A composite is one of the materials widely used nowadays because
composites have advantages of the mechanical properties, corrosion resistance,
light density and simple manufacturing process. This study used glass fiber and
powder as the result of burning rice husk as reinforcement in the material
composite because it is easy to get. In addition, the abundant materials and the
ingredients in rice husk containing a lot of lignocellulose material cause strong
and rigid properties. Therefore they can be made as a composite material.
This study aimed to indentify the effect of volume particle fraction
generating from the use of rice husk using a volume fraction of 0%, 2%, 4%, 6%,
8%. The materials used in this study were glass fiber WR 600 (woven roving),
powder produced by burning rice husk and general purpose epoxy type matrix
(Bhiphenol A-epichlorohydrin) Bakelite EPR and hardener versamid 140. The
method used in the composite manufacturing process was hand lay up.
The tensile and impact tests results showed that the volume fraction of 8%
has a more optimal value or the highest. The morphological test results on the
composite sample volume fraction of 8% showed the presence of voids and fiber
breakage because in the stirring process there was air trapped in the matrix
giving rise to voids in the composite.
