Shredding energy consumption of GFRP composite waste

Abstract This work investigated effect of glass fibre fabric structures, feedstock feed rate and screen size on specific shredding energy reinforced plastics (GFRP) waste via a two-level factorial design experiment study. Four types structure, i.e. unidirectional (UD), biaxial (BIAX), triaxial (TRIAX) chopped strand mat (CSM), were impregnated separately with unsaturated polyester resin to manufacture GFRP plates. The was measured using two-wattmeter approach. During shredding, CSM demonstrated relatively flat power consumption curve compared other types. It also noticed that the plate more complex woven TRIAX, required higher for especially combination high small size. found mechanical efficiency only around 8.2-15.7% 0.8-2.2% at 60 kg/hr 10 respectively. adopting larger lower could reduce energy.
