Abstract:

With waste printed wiring board powder employed as composites filler,new waste filler reinforced composites were developed via moulding technology process.Effects of the molding temperature molding pressure and waste filler content on the mechanical properties of waste filler reinforced composites were studied,and the application of waste composite was discussed.The results show that,with the increasing molding temperature,pressure and filler content,the composite anti-flexural strengths increase first and then decrease.Under the optimized moulding conditions,a composite with flexural strength of 107MPa and impact strength of 10kJ/m2 can be developed.
