| 摘要 |
The invention concerns a prepreg made from uni-directional reinforcement fibres, such as glass fibres, carbon fibres or aramid fibres, impregnated with a duroplast mixture, the duroplast mixture containing an epoxy resin, a phenolic resin and, optionally, an accelerator, plus, optionally, additives such as fillers, fireproofing agents, elastification agents, wetting agents, etc. A prepreg of this kind can be used as the starting material for hot-pressed composites and for composite products with high long-term heat resistance and high resistance to chemicals. |
