Abstract

Abstract: In this paper, different concentrations of KH570 solution and 0.5wt% PEK-C solution were used to modify CF in turn, and CF/PPS composites were prepared by compression molding. The CF/PPS composites were characterized by means of X-ray photoelectron spectroscopy (XPS), scanning electron microscope (SEM), X-ray diffractometer (XRD), and universal material testing machine. The results show that after sequentially treating CF with 2wt% KH570 solution and 0.5wt% PEK-C solution, the interfacial properties and bending properties of the composites are significantly improved. Compared with the unmodified CF/PPS composites, its bending strength increased from 709 MPa to 953 MPa, an increase of about 34.4%, and the ILSS increased from 23.8 MPa to 53.3 MPa, an increase of about 123.9%.
