摘要
目的:比较碳化硅晶须(SiCw)、硼酸铝晶须(ABw)、氧化锌晶须(ZnOw)增强复合树脂的弯曲性能,筛选最优配方。方法:测定复合树脂的弯曲强度和弯曲弹性模量。结果:β-SiCw熔附SiO2纳米粒子(β-SiCw/SiO2)、ABw熔附SiO2纳米粒子(ABw/SiO2)、ZnOw(四针状)均可以提高复合树脂的弯曲性能。本实验条件下复合树脂弯曲性能的最佳方案是:填料为ABw/SiO2,用量为60%时。结论:每一种晶须填料均可以提高复合树脂的弯曲强度和弯曲弹性模量,提高的程度与填料的用量相关。
Objective： To compare the flexural properties of silicon carbide whisker（SiCw） , aluminium borate whiker （ABw） and zinc oxide whisker （ZnOw） , and to discover the optimal plan. Methods： The flexural strength and flexural mode were measured. Results： All of the β -SiCw/SiO2, ABw/SiO2 and ZnOw can improve the flexural properties of resin composite. When the filler is ABw/SiO2 and the usage amount of it is 60 mass portion, the flexural properties in this experiment is the best. Conclusion： Each kind of whisker could improve flexural strength and flexural mode of resin composite and the improved degree was related to the usage amount of the fillers.
