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

open access: yesAdvanced Manufacturing: Polymer & Composites Science, 2018
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
