PBO纤维复合材料的研究及进展

Research and Development of PBO Fiber Composites

聚对苯撑苯并二恶唑(PBO)纤维表面化学惰性较强,应用方面受到了较大的限制。PBO纤维经表面改性后可与其它化合物形成复合材料,如PBO树脂基增强复合材料以及PBO纤维纳米复合材料等,PBO纤维复合材料凭借优异的力学及化学性能在各领域都获得了较大的应用及发展。介绍了PBO树脂基增强复合材料和PBO纤维纳米复合材料的应用及发展。近些年,PBO纤维复合材料已经逐步取代传统的金属材料。但是目前PBO纤维复合材料仍有较大的研究空间,其开发对于航空、航天和国防等高新技术领域材料及产品更新换代具有重要意义。

The surface of poly-p-phenylene benzobisthiazole(PBO)fiber is modified,and forms composite materials afterreacting with other materials,such as PBO resin matrix and PBO fiber nano-composites.In recent years,PBO fiber compositematerial was applied and developed because of its excellent properties.The PBO fiber and composite materials was introduced.Theapplication and development of the PBO resin matrix and PBO fiber nano-composites was introduced.The development of PBOfiber composite materials is important for the hi-tech materials in the area of aerospace,aviation and national defense and the updateof materials products.Besides,in order to explore the environmentally-friendly materials,high performance composite materials ofPBO fiber are the focus of attention of researchers and replaces some traditional materials.So,the PBO resin matrix and PBO fibernano-composites have a lager space research.
