会议名称：ECCM18 - 18th European Conference on Composite Materials

会议日期：24-28th June 2018

会议地点：Athens, Greece

会议简介：18th European Conference on Composite Materials is organized by the Department of Mechanical Engineering and Aeronautics of the University of Patras, under the patronage of the European Society for Composite Materials (ESCM). ECCM is the Europe's leading conference on composite materials and, traditionally, host scientists, engineers and designers, both of Academia and Industry, coming from all the areas of the world. The size of the worldwide composite community has been growing significantly in the last years and over 1,000 participants are expected to attend the event. The conference will attract internationally renowned scientists and engineers in the field of aerospace, automotive and mechanical engineering and will bring together the scientific and the application-oriented world.

Title：Energy Absorption Properties of CFRP Composites Tube with Discontinuous Plies

Author：Zhibo Xin, Yugang Duan, Jin Zhou

Abstract: The carbon fiber reinforced plastic (CFRP) composite with overlapped discontinuous plies have been proven to exhibit advanced pseudo-ductility. This paper aims to use a similar concept to design CFRP square tube and investigate the effect of energy absorption capability with two cut-ply strategy: i) the cut direction had an angle of α tilted respect the loading direction which is the axial direction of the square specimens; ii) the cut direction had an angle of β tilted follow the fiber orientation. The quasi-static axial compression tests are conducted to explore failure process, crashworthiness characteristics and the corresponding energy absorption mechanisms. Experimental results showed that cutting angle α and β have a significant influence on the energy absorption performance. Increasing the angle of α from 15° to 70° led to an increase in specific energy absorption (SEA) from 51.0J/g to 73.1J/g. On the contrary, SEA decreased (from76.7 J/g to 56.9 J/g) with increasing β. However, they all exceed the SEA of continuous specimen (56.2J/g). This work demonstrates that the energy absorption performance of composite tubes can be improved by proper selection of cutting strategy and cutting angle.
