F-3A/ E 与F-12/ E 复合材料圆管轴压性能对比

采用缠绕成型的方法制备了F-3A/ E 复合材料薄壁圆管,通过对比试验研究了树脂配方和增强
纤维对管件轴压性能的影响,并对缠绕管件的轴压破坏模式进行研究。同时与F-12/ E 复合材料进行了对比
分析。结果表明:(1)TH-1 配方适合F-3A 纤维制备复合材料;(2) F-3A/ E 复合材料缠绕管件轴压承载力比
F-12/ E 复合材料管件的高16. 5% ~23. 9%,且轴压性能具有良好的稳定性;(3) F-3A/ E 管件轴压破坏形式
表现为脆性破坏,而F-12/ E 管件轴压则表现为韧性破坏模式。

Axial Compressive Properties of The F-3A/ E and F-12/ E Composite Tube

Filament winding process is used to fabricate the F-3A composite tubes,and the effect of resin formula
and reinforced fiber on axial compression property as well as the failure mode of composite tubes was studied. The
results reveal that(1)The TH-1 resin formula shows excellent compatibility for the F-3A fiber composite,(2)The axial
compressive strength of domestic F-3A fiber composite tube is higher than F-12 composite tube up to 16. 5% to
23. 9% and higher stability,(3)The failure mode of domestic F-3A fiber composite tube appears brittleness while F-
12 fiber composite tube shows toughness.
