聚芳基乙炔具有杰出的耐高温性能,可作为热防护材料的基体树脂,并且其碳纤维/PAA复合材料的耐烧蚀性能和可靠性远远高于传统的碳/酚醛,其耐高温性能优于当前性能最好的聚酰亚胺(PI),结构稳定性和吸湿性远优于环氧树脂,因此在航天器部件方面有很大应用潜力。主要介绍了聚芳基乙炔的单体、合成方法、性能特点、改性及其复合材料的研究进展和发展前景。
Polyarylacetylene has excellent high temperature resistance and can be used as the matrix resin of thermal protection materials, and the ablation resistance and reliability of its carbon fiber / PAA composite are much higher than the traditional carbon / phenolic, its high temperature resistance Polyimide (PI), which has the best properties currently available, has far superior structural stability and hygroscopicity than epoxy resins and therefore has great potential for applications in spacecraft components. The polyarylacetylene monomer, synthesis method, performance characteristics, modification and composite materials research progress and development prospects are introduced.
