PROBLEM TO BE SOLVED: To obtain a fiber-reinforced resin composite or prepreg which is resistant to ignition, has good mechanical properties after heat exposure, and is suitable for the use in transportation means such as railroad cars. SOLUTION: This composite comprises a fibrous reinforcement and a matrix resin, does not substantially ignite in the ignition test according to the test method No. 81 of the Ministry of Transport, and exhibits a compression strength after impact of 15 kgf/mu<2> or higher and an interlayer shear strength of 7 kgf/mm<2> or higher when measured after heat exposure in a heated oven at 250 deg.C for 10 min. The matrix resin comprises a nonhalogen epoxy resin, a metal oxide, a thermoplastic resin having a glass transition temp. of 120 deg.C or higher, and a curative for an epoxy resin. |
