Abstract: Objective: To study effect of different β-SiC nanowires additive on the mechanical properties of POSS composite resin. Methods: β-SiC nanowires were added to POSS composite resin at different mass fraction of 0%, 0.5%, 1.0%, and 1.5%. The mechanical properties of modified resin specimen were detected, including hardness, elasticity modulus, and abrasive resistance. Results: Statistical analysis showed that hardness and elasticity modulus were the highest in the 0.5% group (P<0.05), and the scratch depth in the 0.5% group was the least (P<0.05). Conclusion: Appropriate addition of β-SiC nanowires significantly enhanced the mechanical properties of POSS composite resins.
