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

Abstract: | 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. |
