Compression molding of reused in-process waste – effects of material and process factors

Effective strategies for the reuse and recycling of in-process prepreg waste are needed to reduce economic and environmental costs. In this paper, we investigate the compression molding of prepreg waste converted into scrap “chips” (or strands). Material is randomly distributed within a lab-scale cl...
