PROBLEM TO BE SOLVED: To provide a method for controlling the resin reaction rates in resin curing which allows a relatively long out-time of a prepreg and has a relatively low cure temperature and/or relatively short cure time.SOLUTION: A thermosetting resin composition contains a plurality of polymer nanoparticles. At least some of the polymer nanoparticles release either a catalyst or a hardener during a resin curing process. The catalyst or hardener alters the reaction rate of the resin. The polymer nanoparticles have a particle cross-sectional width of 10-200 nm, and constitute up to 75% by volume of the resin.SELECTED DRAWING: None |
