“…The energy crisis has created a strong demand for lightweight structural materials in various industries. Compared with traditional thermosetting composites, thermoplastic composites produce fewer harmful chemicals, have no curing stage and possess good recyclability, weldability and high production capacity [ 1 , 2 ]. Meanwhile, short-fiber-reinforced thermoplastic composites (SFRTPCs) have been used in a variety of industrial applications, such as automotive, aerospace, construction and electronic packaging, due to their advantages with low density, high strength and good environmental resistance properties [ 3 , 4 ].…”

Recently, short-fiber-reinforced thermoplastic composites (SFRTPCs) have been playing a more and more crucial role in the application of automotive interior materials due to their advantages of low density and environmental resistance properties. However, their relevant mechanical properties need to be optimized. Previous investigations revealed that the surface modification of fibers is useful to improve their mechanical properties. In this work, carbon fiber (CF)-reinforced polylactic acid (PLA) composites modified with MXene and graphene oxide (GO) were prepared by twin-screw extrusion and injection molding methods. Short CF was firstly modified with polyetherimide (PEI), then different weight ratios of MXene-GO (1:1) were subsequently modified on PEI-CF. Finally, the flexural properties and failure mechanisms were analyzed. The results showed that MXene-GO was successfully coated on CF surface, and the flexural strength and modulus of CF-PEI-MXene-GO-reinforced PLA (CF-PEI-MG/PLA) composite were improved compared to that of CF/PLA composite. In addition, the fracture sections of the composites were flat and white, and the fibers bonded well with PLA for CF-PEI-0.1MG/PLA composite compared to CF/PLA composite. The present study could provide a reference for further improving the mechanical performance of PLA-related composites.
