摘要： 目的:研究β-SiC纳米线的不同添加量对POSS复合树脂力学性能的影响。方法:将质量分数分别为 0 、0.5 、1.0 、1.5的β-SiC纳米线作为添加剂加入poss复合树脂。对各组试件的硬度、弹性模量、耐磨性等力学参数进行测试,对实验数据进行统计学分析。结果:统计学分析结果表明,0.5％组的硬度值、弹性模量值最高,划痕深度值最小,与其他各组比较,差异均有统计学意义(P<0.05)。结论:添加适量β-SiC纳米线可以显著增加POSS树脂的机械性能。

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.
