A prepreg is a fabric impregnated with an epoxy mixture. The article considers the process of curing the epoxy mixture of hot curing together with a nylon binder in the form of a tape at room temperature for 36 days. The results of experiments by three-point bending on the tensile testing machine Testometric 115 for 30 samples and eight control days of measurement are presented. Analysis of the results of these experiments showed that the observed curing of prepregs begins from 13 days after their manufacture.
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.
