RESEARCH ON THE BENDING CAPABILITY OF COMPOSITE FIBER REINFORCED PLASTIC TUBE WITH RECTANGULAR CROSS SECTION
摘要
Abstract
According to the bending capability of rectangular cross section(RCS) tube made of carbon fiber reinforced plastic (CFRP),five different layer schemes of the tubes were designed.The finite element software Abaqus was used to analysis the three point bending test,and the strain of the middle position on the bottom surface was obtained.Then,the three point bending test was carried out on the universal testing machine,and the strain of the middle position on the bottom surface was obtained by using FBG sensor.The load-strain curve of the 5 schemes was fitted,the load-strain curve and bending stiffness were obtained.It is found that the experimental results are in good agreement with the analysis results.The results show that the higher the ratio of 0 degrees,the better of the bending performance.关键词
