Production of thermoset composites containing thermoplastic fillers

摘要: A process for increasing the damage tolerance in thermoset composites without loss of processibility or mechanical properties thermoset, by controlled solubility a thermoplastic filler base thermoset. The includes mixing spherical particles selected thermoplastic, such as polyimide, particle size ranging from about 10 to 80 microns, with hot resin, bismaleimide, form uniform dispersion resin mixture, employing 5 40% weight mixture two resins. are non-agglomerating and insoluble mixture. is then applied fiber reinforcement, carbon tapes, pre-pregs. Upon curing at elevated temperature, dissolve forming composite no definable boundary interfaces between thermosetting
