PREPREG AND METHOD FOR MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a prepreg stable at room temperature and capable of mold releasing by a primary hardening at a comparatively low temperature (70-100 deg.C) and a short time (Less than 10 hrs), and imparting a FRP molded hardened article having excellent heat resistance and mechanical properties by a next secondary hardening at above 100 deg.C. SOLUTION: This prepreg including a reinforcing fiber and a thermosetting resin composition comprises the thermosetting resin composition including two kinds of thermosetting resin compositions comprising (A) a thermosetting resin composition capable of hardening at temperatures lower than 100 deg.C in 10 hrs or less and (B) a thermosetting resin capable of hardening at 100 deg.C or higher.
