通过将超声直接作用于聚芳基乙炔树脂(PAA)的方法,研究了超声处理对PAA树脂本体的影响,并把超声处理应用于RTM成型工艺中,研究了超声处理对平板CF/PAA复合材料力学性能与烧蚀性能的影响.结果表明:经过最佳处理时间60s左右的超声处理,碳纤维/聚芳基乙炔树脂复合材料的力学性能以及耐烧蚀性能均有所提高.复合材料综合性能的提高主要是由于超声处理后树脂与纤维之间的浸润性提高,纤维与树脂之间的界面粘结性能得到改善.
Influence of uhrasonic treatment on polyarylacetylene (PAA) resin was studied. The effects of ul-trasonic treatment on mechanical performance and ablation performance of CF/PAA composite were studied as well. The results indicate that the mechanical performance and ablation performance of CF/PAA composite are improved after the ultrasonic treatment of 60s. The improvement of composite performance is attributed to the improvement of wetting cap ability of CF and PAA resin after ultrasonic treatment, which results in the im-provement of interfacial performance of CF and PAA resin.
