Abstract

The aim of this study was to analyze the storage period and curing rate of prepregs at room temperature. 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.
