Abstract

A novel phenolic resin suitable for hot-melt impregnation process was developed through copolymerization. The curing reactivity, gel properties and viscosity of the resin were tested to evaluate the resin reaction process. A prepreg of this resin and glass fabrics was developed with hot-melt process. The cured phenolic prepreg laminates havebalanced mechanical properties. It can be used to manufacture interior structures for airplanes and high-speed trains or other applications with flame retard requirement.
