70℃ 내지 110℃와 같은 낮은 외부 적용 온도에서, 허용 가능하게 짧은 사이클 시간으로 경화될 수 있는 반응성 에폭시 수지를 기반으로 하는 프리프레그 및 프리프레그의 스택은, 경화제는 함유하지만 하드너는 함유하지 않는 에폭시 당량 200 내지 500의 에폭시 수지를 포함한다. Prepregs and stacks of prepregs based on reactive epoxy resins that can be cured at lower externally applied temperatures such as from 70° C. to 110° C. with acceptably short cycle times comprise epoxy resins of epoxy equivalent weight from 200 to 500 containing a curing agent but no hardener.
