In this work, the interfacial shear strength (IFSS) of polyamide 66/epoxy resin composite was improved through the surface modification of polyamide 66 by low-temperature oxygen and nitrogen plasma. Microbond test was used to study the IFSS of the composite. In addition, the composition, microstructures and deboned morphology of the fiber were investigated using the methods of XPS, AFM and SEM. The results show that the polar functional group, such as -NH2, -COOH, and -OH, were successfully introduced on the surface of the polyamide 66 fiber by plasma treatment. Meanwhile, the surface roughness of the polyamide 66 also increased. After oxygen and nitrogen plasma treatment, the interfacial shear strength of the composite increased to 3.52 MPa and 4.89 MPa, respectively, which is 2 times and 3 times higher than that of the untreated composite. Nitrogen plasma treatment showed better results than oxygen plasma treatment.
