ABSTRACT:
Preformed carboxylated rubber particles are effective for toughening fiber reinforced composite structures based on thermoset resins such as epoxy resin formulations. The composites are effectively toughened by adding the carboxylated rubber particles to the matrix resin prior to curing the composite.
