Preparation and performance test of Q235 steel and carbon fiber laminated composite material

Abstract

With the rapid development of modern industry, research on high-performance materials has played a certain promoting role. This article selects common hollow round tube steel on the market, and uses carbon fiber cloth wrapping to form a laminated material for three-point bending experiments. The specimens tested include 8mm thick steel, 4mm thick steel plus 2mm thick carbon fiber cloth, reduced-weight 6mm thick steel, and materials composed of carbon fiber cloth only. By comparing the experimental results, it is concluded that the performance of the carbon fiber composite specimens is significantly better than that of the steel specimens of the same weight, both for the steel weight-reducing specimens and for the steel specimens wrapped with carbon fiber. This article uses computer finite element simulation to optimize the size of the three-dimensional model, and determine the laying angle and number of layers of carbon fiber, Next, analyze the simulation results, and finally analyze the source of errors and draw conclusions through comparative experimental data.
