Abstract

The effect of time and storage conditions of the prepreg, based on the phenol-formaldehyde binder VSF-16M and T-64 glass fiber cloth (VMP), on its technological properties was evaluated. Elastic-strength properties of GRP based on this prepreg are investigated. To assess the prepreg of fiberglass, the differential scanning calorimetry (DSC) method was used and the gel time of the binder in it was analyzed. Based on the results of the study, conclusions were drawn as to the shelf life of the prepreg.
