摘　　要：主要针对片状模塑料(SMC)快速固化引发体系进行了研究。通过对不同类型的引发剂以及不同复合比例的引发体系对树脂糊固化特性及贮存寿命影响的研究,得到了复合引发体系的最佳比例,实现了树脂糊贮存寿命与固化时间的平衡。同时,还研究了复合引发体系对SMC物理机械性能的影响。结果表明:采用复合引发体系可以实现SMC固化时间缩短40%,材料的各项物理机械性能基本保持不变。A dual initiator system for rapid cure SMC processing was developed and an optimum recipe of the dual initiator system was obtained by investigating the effects of initiator types and their proportions on the cure and shelf life of SMC paste,with the balance of curing time and shelf life of SMC paste achieved.Furthermore,the effects of the rapid cure initiator system on the mechanical properties of SMC were investigated.The results showed that the balance between curing time and shelf life of SMC could hard...
