Abstract: The specific energy absorption of thin-walled hybrid carbon fibre tubes is significantly enhanced by matrix materials. To further improve the energy absorption characteristics of CFRP, in this study, three types of CFRP thin-walled tubes were produced using various resin-modified carbon fibre prepregs, and quasi-static compression tests were carried out on the three types of tubes. By contrasting the energy absorption characteristics of three groups of tubes through experimental data, it was feasible to determine the impact of matrix modification on the energy absorption properties of CFRP tubes. The best absorption effect tube material was chosen for the relevant mechanical properties tests to obtain the material mechanical parameters, and the quasi-static compression process was simulated numerically using the explicit nonlinear finite element software LS-DYNA. The good correlation between the simulation data and the experimental results verified the reliability of the test method and the numerical model. On this basis, the effects of different ply parameters such as ply ratio, ply angle, and ply sequence on the energy absorption characteristics of the hybrid tubes were investigated by adding other modified fibre materials to the common carbon fibre material and performing finite element simulation.
