摘要

树脂基体作为复合材料的粘结剂,直接影响着热塑性复合材料的成型工艺和产品性能。采用压缩成型工艺制备了碳纤维增强聚醚酰亚胺(CF/PEI)和聚芳醚酮(CF/PAEK)复合材料。研究了tpc的界面、层间和低速冲击性能。结果表明:CF/PEI复合材料的界面剪切强度为~116 MPa, CF/PAEK复合材料的界面剪切强度为~78 MPa;但CF/PAEK的层间和低速冲击性能优于CF/PEI。CF/PEI的I型断裂韧性(G IC)和II型断裂韧性(G IC)分别为~1051 MPa和~1060 MPa。CF/PAEK分别为~1786 MPa和~2584 MPa。CF/PAEK冲击后的抗压强度(~321 MPa)比CF/PEI (~230 MPa)高40%。

The Effect of Resin Matrix on the Properties of CF/PEI and CF/PAEK Thermoplastic Composites
As the adhesive for composites, the resin matrix directly impacts the molding process and product performance of thermoplastic composites (TPCs). Carbon fiber-reinforced polyetherimide (CF/PEI) and polyaryletherketone (CF/PAEK) composites were prepared by a compression molding process. The interface, interlaminar, and low-speed impact properties of TPCs were studied. The results show that the interfacial shear strength of the CF/PEI composite is ~116 MPa, while the CF/PAEK composite is ~78 MPa. However, the interlaminar and low-speed impact performance of CF/PAEK is better than CF/PEI. Type I fracture toughness ( G IC ) and type II fracture toughness ( G IIC ) of CF/PEI are ~1051 MPa and ~1060 MPa. But those of CF/PAEK are ~1786 MPa and ~2584 MPa, respectively. The compressive strength after the impact of CF/PAEK (~321 MPa) is 40% higher than CF/PEI (~230 MPa).
