The invention provides methods and systems for curing composites and associated microcrack-resistant composites. A method for curing a composite including a thermoset resin, a reinforcement material and a thermoplastic additive, the thermoplastic additive having a melt onset temperature, the method including heating the composite to increase a resin temperature of the thermoset resin and, during the heating, controlling the resin temperature such that the resin temperature exceeds the melt onset temperature prior to the thermoset resin achieving a degree of cure of 98 percent.

    本发明的名称是用于固化复合材料的方法和系统和相关的抗微裂复合材料。用于固化复合材料的方法,该复合材料包括热固性树脂、增强材料和热塑性添加剂,该热塑性添加剂具有熔融起始温度,该方法包括加热复合材料以提高热固性树脂的树脂温度,并且在加热期间控制树脂温度,使得树脂温度在热固性树脂达到98%的固化度之前超过熔融起始温度。
