Abstract (en)
[origin: WO0132755A1] The aim of the invention is to obtain prepregs on the basis of duroplastic, oleochemical matrices that can be stored at room temperature. To this end, a fiber material that preferably contains natural fibers is contacted with a matrix material at temperatures of 40 to 80 DEG C in the presence of a suitable catalyst and the fiber material impregnated with the matrix is cooled to temperatures of 30 DEG C and less. The matrix material is chosen from a fatty substance with at least 12 C atoms that contains epoxide and/or hydroxyl groups, a cross-linking agent and a catalyst, and the matrix material has a Brookfield viscosity of 600 to 1400 MPa at temperatures of 40 to 80 DEG C.
