Abstract：

In order to explore the influence of carbon fiber on the tensile properties of composites, the carbon fiber reinforced aluminum matrix composite castings were prepared by vacuum suction casting method and their tensile properties were tested. The influence of carbon fiber content and carbon fiber length on the stress and strain distributions of carbon fiber reinforced aluminum matrix composite was analyzed by combining the experimental data with the Geodict software. The simulation results are in good agreement with the experimental data, which provides research basis for the follow-up work and performance improvement of carbon fiber reinforced aluminum matrix composite prepared by vacuum casting method. The results show that with the increasing of carbon fiber content, the reinforcing effect of fiber on the tensile properties of material is better. Furthermore, with the increasing of carbon fiber length, the reinforcing effect of fiber on the tensile properties of material gradually decreases and becomes stable after 5 mm. When the fiber length is 1 mm, the tensile properties of composites are superior.
