摘要: 本文通过对不同粗化方式和不同吹砂次数后的复合材料表面形貌和胶接强度进行研究,对比了目前常用的复合材料粗化方式的差异,并分析了吹砂次数对胶接强度的影响机理,探讨了树脂砂回收利用的可行性。结果表明,树脂砂吹砂能够有效去除表面树脂而不伤及纤维,且粗化程度均匀。提高吹砂次数可在一定程度上提高粗化效果,但过度吹砂会损伤纤维反而降低胶接强度,最佳的吹砂次数为二次。对于回收利用的树脂砂,可通过提高吹砂次数来达到首次吹砂的效果。

Abstract: This paper studied the surface appearance and bond strength of composites with different surface roughing treatment and different sandblasting times. The result shows that resin sandblasting can remove surface resin of composites effectively without breaking fiber. As the times of resin sandblasting increases, the roughness effect increases. However, too much time can destroy fiber and reduce tensile lap-shear strength. Two times resin sandblasting is optional. By increasing the sandblasting time of resin sand, the recycle resin sand can attain the effect of first use.
