		abstract={Composites are material structures composed of two or more constituents 
macroscopically combined without dissolving each other. They are composed of a 
reinforcing phase and a matrix and have the advantages of better strength-to density ratio and corrosion resistance, which makes them an alternative to the 
increasingly scarce and increasingly used metals. Therefore, alternative materials 
such as composites are increasingly being developed these days, especially for the 
manufacture of helmets.
The purpose of this study is to investigate the effects of the volume fraction 
of wood powder particles on the bending strength and impact strength of 
composite materials. The particle volume fraction variations used were 10%, 15% 
and 20%. The materials used in this research are sawdust particles mixed with 
epoxy resin as a matrix. The material manufacturing process was done by hand 
lay-up technique.
In the impact test, the test results show that the 20% volume fraction 
provides the highest impact strength with a value of 0.10249 J/mm², while the 
10% volume fraction provides the lowest impact strength with a value of 0.06124 
J/mm². In addition, in the bending test, the 10% volume fraction gave the highest 
bending strength with a value of 32.457 N/mm², while the 20% volume fraction 
gave the lowest bending strength with a value of 11.900 N/mm². These results 
indicated that the addition of sawdust particles affected the bending and impact 
strength of composites using epoxy matrices.}
