摘要/Abstract

摘要： 以核壳橡胶作为环氧树脂增韧剂,制备了一种高温固化环氧基体与玻璃纤维预浸料。结果表明,核壳橡胶用量为5phr时不影响环氧树脂对玻璃纤维的浸渍能力,此时核壳橡胶增韧后环氧/玻璃纤维层压板获得了较好的增韧效果,冲击强度达到278.1kJ/m²,比增韧前提高了20.0%;Ι型层间断裂韧性提高明显,达到982.0J/m²,比增韧前提高了35.4%;径向拉伸强度达到749.5MPa,比增韧前提高了16.5%,拉伸模量没有明显变化;SEM结果表明核壳橡胶增韧基体树脂的破坏断面为典型的韧性破坏,且树脂与玻璃纤维浸润性好、粘接力强。

Abstract: A glass woven fabric prepreg of the epoxy matrix resin toughened with core-shell rubber particles was prepared. The results showed that the core-shell rubber will not affect the epoxy resin infiltration capacity of glass fiber and fabric prepreg laminate achieved excellent toughness by using just 5phr core-shell rubber as tougher, impact strength of which reached 278.1kJ/m² and it increased by 20.0% than that before toughening, fracture toughness G_IC of which reached 982.0J/m² and it increased by 35.4% than before toughening; tensile strength of which reached 749.5MPa and it increased by 16.5% than that before toughening, tensile modulus of laminate toughened with core-shell rubber particle is hardly decreased, the surface morphology observed by scanning electron microscope exhibited typical toughness fracture. The resin has good infiltration and adhesion with glass fiber.

Key words: core-shell rubber particle, prepreg, mechanical properties of compound material, mode interlaminar fracture toughness G_IC of laminates
