Abstract:Considering the increasing composite waste accumulation, this work explores the feasibility of replacing virginal carbon fibers (VCFs) and virginal glass fibers (VGFs) with recycled fibers for injection molded polyetherimide (PEI) composites. Extensive characterizations were conducted to reveal effects of sulfuric acid recycling process on mechanical properties of fibers and their composites. It was shown that strength retention rates of recycled carbon fibers (RCFs) and recycled glass fibers (RGFs) were 81.6%… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
