Investigation the effect of natural materials on wear and hardness properties of polymeric composite materials

الملخص EN

This research studied the properties of orange and pomegranate reinforced unsaturated polyester with different powder weight fraction Wf.

The orange and pomegranate powders were added to unsaturated polyester at weight fraction (0,4 ,8 & 11 wt%) with grain size (53µm).

The composite specimens were prepared by hand lay-up technique and cutting according to (ASTM) for wear test, hardness test to obtain of the composite specimens.

The results show that the wear rate for all tested specimens increases with increase of time of applied load and the wear rate decreases with increasing weight fraction of particles.

Also the best value of properties was obtained for composite materials reinforced with pomegranate peel at (=11wt%) than composite materials reinforced with orange peel at this value.
