Abstract

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.

Key words: composites, adhesive bonding, surface roughness, resin sand
