Study on Axial Compressive Properties of Multidirectional Filament Wound Tubes

The axial compressive properties of the multidirectional filament wound tubes(MFWT) were studied both theoretically and experimentally.Based on the classical laminate theory,the mechanical analysis model of the tubes was established and implemented by the program of Matlab language,from which the axial compressive strength was predicted.Then the specimens with different parameters were fabricated and tested under axial compressive load respectively.Generally,the theoretical model meet the experimental results well.Furthermore,the test results were analyzed,which show that the axial properties of the MFWT are obviously strengthened with the incorporation of the axial reinforcement.
