Abstract Because of advantages such as remarkable mechanical properties and the ease of recycling, fiber‐reinforced thermoplastic polymer composites have been increasing in importance in industrial, transport, and sporting potential extraordinary applications. To fabricate polycarbonate (PC) components with lightweight and high mechanical properties, short glass fiber (SGF), long carbon fiber (LCF) reinforcement, and foaming technology were used in this study. The effects of SGF, LCF, and SGF/LCF on the mechanical properties and foaming quality of PC samples were carefully investigated and compared. The results show that SGF has a better foaming nucleation effect than LCF, and the mechanical enhancement effect of LCF is more significant than that of SGF. The combination of SGF and LCF can effectively improve the cell quality of foam samples and significantly enhance their mechanical properties. Therefore, a comprehensive application of the fiber‐reinforcement effect of PC resin is proposed. Highlights LCF and SGF reinforced PC foams have been successfully fabricated. Hybrid reinforced effect of LCF and SGF on PC foams was verified.
