FIELD: process engineering.SUBSTANCE: invention relates to composites. Proposed prepreg comprises components A, B and C, component A being located at one or both surfaces of the ply containing components B and C. Component A is a nonwoven material including thermoplastic elastomer and/or polyolefin with tan ? equal to 0.06 or larger at 10°C measured at measurement of viscoplasticity and is incompatible with component B being the first composition of epoxy resin and C making a reinforcing fiber. Proposed method of prepreg making comprises impregnation of component C with component B to produce prepreg precursor and bonding component A with prepreg precursor.EFFECT: high stiffness, strength and damping properties.22 cl, 15 dwg, 33 tbl, 103 ex |
