<![CDATA[The strength of the mechanical and physical properties of particle composite materials is influenced by the volume fraction of the powder and matrix. Fraction variations used are 30:70%, 50:50%, and 70:30% with the hand lay up method. The pretreatment was carried out by soaking 2% NaOH for 1 hour. The results of the MOE treatment mechanical test received the highest test value at the powder volume fraction of 30:70%, which was 6145.51 kgf/cm² and the highest MOR test value at the 30:70% volume fraction, which was 167.38 kgf/cm². Meanwhile, the highest non-treatment MOE value at the 30:70% powder volume fraction was 5540.9 kgf/cm² and the highest MOR test value at the 30:70% volume fraction was 156.6 kgf/cm². The results of the physical properties test were the highest density at the 30:70% powder volume fraction of 0.87 gr/cm³ and the highest density at the 30:70% non-treatment powder volume fraction of 0.78 gr/cm³. The results of the MOE mechanical test do not meet the JIS A 5908-2003 standard while the MOR mechanical test and physical test have met the JIS A 5908- 2003 standard. The results of microstructure testing showed that at a fraction of powder volume of 30:70% it was seen that the particles were coarser which blended perfectly with the matrix. Meanwhile, in the volume fraction of non-treatment powder 30:70% it looks finer particles and powders with a matrix seem to not glue well, this is because of the wax coating on the powder.]]>
