RESIN COMPOSITION, PREPREG, AND PRODUCTION OR PREPREG
Document Type and Number:
Japanese Patent JP3669090
PROBLEM TO BE SOLVED: To reduce such a trade-off in the viscosity of a matrix resin that a lower viscosity is required during impregnation and a higher viscosity during prepregnation.
SOLUTION: This resin compsn. comprises a thermosetting resin, a free- radical-polymerizable unsatd. compd., and a polymn. initator which generates a free radical when heatd. A prepreg. is produced by a process comprising the step of impregnating a fibrous reinforcement with the compsn. and the step of thermally treating the compsn. contained in the reinforcement.
