F-3A/E与F-12/E复合材料圆管轴压性能对比

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

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。

Filament winding process is used to fabricate the F-3A composite tubes, and the effect of resin formu- la 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-3 A fiber composite, （2）The ax- ial 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.
