Abstract

Phenolic resin has originally advantages of heat proof, fire resistance and less smoke during burning. The CFRP with phenolic resin having these advantages is one of suitable materials in structures of vessels and railway carriages. However, a resole type of phenolic resin generates water formed from the condensation reaction. As a result, the strength of phenolic CFRP varies widely owing to the voids. The authors developed a method of injection molding for fabrication a new type of phenolic CFRP. This CFRP was composed of novolak type of phenolic resin as a matrix and carbon fabrics as a reinforcement. In order to evaluate mechanical properties of phenolic CFRP under high temperature, we carried out tensile test under high temperatures. As a result, the phenolic CFRP showed high mechanical properties under high temperature.
