Abstract
Chopped glass fiber and waste printed wiring board powder reinforced composites were prepared by compression molding. Effects of the shape, content and size of waste powders on the mechanical property of waste filler reinforced composites were studied, and the application of waste composite was discussed. The results show that the mechanical property of composite reinforced by chopped glass fiber and waste printed wiring board powder is better than that of waste powder reinforced composite. Effects of large powders (1-3 mm) on composite properties were better than of small powders (0.25 mm). Large powder mass fraction can reach 65%, and a mixed reinforced composite with flexural strength of 150 MPa and impact strength of 18 kJ/m2 can be developed.
