... that the particles remain in the composite interlayer and do not penetrate the fiber tows ( Ref 20 ). The most common method of interlayer toughening is through adding preformed particle-modified resin on the surface of the prepreg, which, when consolidated and cured, results in an interlayer-toughened composite...
