TOUGHENED RESIN SYSTEMS FOR COMPOSITE APPLICATIONS

摘要

of the thermosetting resins used in composites reinforced with high performance fibers are cured without compromising their ability to treatment by incorporating particles of a thermoplastic material, the size of which is solid at temperatures of micron ambia it is based in the solubilized resin at a temperature below the freezing temperature of the rthermosetting u00e9sine. by a suitable choice of the temperature of solubilization (temperature range) of the thermoplastic material, it is possible to obtain a composite product having improved hardness and interlaminaire intralaminaire, or a combination of both. the invention is particularly useful for systems bismalu00e9imide resins.
