摘要:
 采用正交试验，针对碳纤维增强复合材料（Carbon fiber reinforced composite，CFRP）的注射成型性能进行研究，获得最佳工艺参数组合。通过控制单一变量研究注塑成型工艺参数对试样力学性能的影响，分析各工艺参数的影响机制；利用扫描电子显微镜观察试样断面碳纤维取向，探讨注塑工艺参数对碳纤维取向的影响。结果表明，最优注射压力对试样力学性能提升最大，试样断面碳纤维取向张量最大；熔体温度、模具温度对试样力学性能提升较小；注射时间对力学性能的提升无明显规律。采用最佳工艺参数组合所获得制件的抗拉强度最大值64.45 MPa，弯曲强度最大值141.43 MPa，弯曲模量最大值7315.45 MPa，纤维取向张量最大值0.8396。
Abstract:
 The carbon fiber reinforced composite (CFRP) was used as the research object, and its injection molding properties were studied. The best combination of process parameters was obtained by orthogonal experiment. By controlling a single variable, the influence of injection molding process parameters on the mechanical properties of the sample was studied, and the influence mechanism of each process parameter was analyzed. The orientation of carbon fiber was observed by SEM, and the influence of injection molding parameters on the orientation of carbon fiber was studied. The results show that the optimum injection pressure has the greatest effect on the mechanical properties of the samples, and the orientation tensor of carbon fibers in the cross section of the samples is the largest; the melt temperature and mold temperature have little effect on the mechanical properties of the samples; and the injection time has no obvious law on the improvement of the mechanical properties. Under this process parameter, the maximum tensile strength of the part is 64.45 MPa, the maximum bending strength 141.43 MPa, the maximum bending modulus 7315.45 MPa, and the maximum fiber orientation tensor 0.8396.
