Abstract

Fibre composites are increasingly used in manufacturing. They are widely used in pools, marine-craft and automobiles. The methods of manufacture create 5~10% waste material which is costly and harmful to dispose of. In this project, the prospect of reuse and recycling of this waste material is considered. The prospect of using ground waste GFRP in further glass fibre composites is explored. An economical process for grinding is designed and the
effects of the ground recyclate on material properties is determined experimentally. The cost of implementing this process is calculated and found to show a net saving.

Tests show that tensile and flexural strengths initially increased with maximums around the 10% and 16%wt recyclate/resin ratio respectively. Elastic and flexural modulus’ initially increased with maximums at 10% and 13%wt recyclate/resin ratio respectively. Impact
toughness decreased with increasing amounts of recyclate and preliminary DMA tests show increases in storage modulus and glass transition temperature. Curing rates increased and
reduced amounts of catalyst are required as amounts of recyclate increased.
