摘　　要：随着我国快速发展的材料研究,复合材料受到各方面广泛关注,尤其是在航空等高新科技领域应用愈加广泛。其中较为突出的CFRP材料,即碳纤维增强树脂基复合材料因其特殊的优势,在航空航天器应用上,得到了大量应用,以其轻量化、强度高等优点,降低了燃油成本。在改善材料层间结构方面,由于层间力学性能和纤维铺层性能较为薄弱,出现分层损伤概率较大,会降低整体材料的力学性能。为改善这种局面,可以引入离位增韧技术,采用尼龙无纺布(PNF)作为增韧层,可大幅度增强复合材料的韧性。With the rapid development of materials in China, composite materials are widely concerned by all aspects, especially in aviation and other high and new technology applications more widely.Among them, the more prominent CFRP materials, namely carbon fiber reinforced resin matrix composites, have been widely used in aerospace applications because of their special advantages, and have the advantages of light weight and high strength, which reduces the fuel cost.In improving the interlayer structure of the material, due to the interlayer mechanical properties and fiber laying performance is relatively weak, there is a greater probability of stratification damage, will reduce the overall mechanical properties of the material.To improve this situation, can be introduced from the toughening technology, the use of nylon non-woven （PNF） as a toughening layer, can greatly enhance the toughness of composite materials.
