Abstract

Los prepregs estables para el almacenamiento a temperatura ambiente, sobre la base de matrices duroplásticas oleoquímicas, se obtienen cuando se pone encontacto un material de fibras, preferentemente conteniendo fibras naturales, con un material que constituye la matriz, a temperaturas de 40 hasta 80sC enpresencia de un catalizador, enfriando luego el material de fibras impregnado con la matriz a temperaturas de 30sC y menores, donde el material de la matriz hasido seleccionado de una sustancia grasa con por lo menos 12 átomos de C, que contiene grupos epoxi y/o grupos hidroxilo, un reticulante, así como uncatalizador, y que el material de la matriz presenta una viscosidad Brookfield de 600 hasta 1400mPas a temperaturas de 40 hasta 80sC.Stable prepregs for storage at room temperature, based on oleochemical duroplastic matrices, are obtained when a fiber material, preferably containing natural fibers, is placed in contact with a matrix constituting material, at temperatures of 40 to 80sC in the presence of a catalyst, then cooling the fiber material impregnated with the matrix at temperatures of 30sC and below, where the matrix material has been selected from a fatty substance with at least 12 C atoms, which contains epoxy groups and / or hydroxyl groups , a crosslinker, as well as a catalyst, and that the matrix material has a Brookfield viscosity of 600 to 1400mPas at temperatures of 40 to 80sC.
