Resin system of bismaleimida curavel heat pre impregnated and impregnated with resin matrix, curavel for heat and material composito cured

摘要

Toughened bismaleimide resin systems capable of preparing carbon fiber reinforced composites having compression after impact strengths of greater than 40 Ksi are prepared from bismaleimide matrix resin systems containing a member of a limited set of thermoplastic polyimides in particulate form.
