摘要:The adhesion properties of ceramic/hybrid fiber reinforced plastic (FRP) adhesively bonded systems were investigated with variations in the FRP surface roughness. The FRP substrate was subjected to mechanical abrasion in order to produce the surface roughness. The contact angles of wa

ter, formamide, and ethylene glycol on the FRP substrate were determined, and double lap shear and flexural tests were ud to measure the joint strength of the ceramic/FRP adhesively bonded systems. In addition, the fracture surface of the adhesive layer at the adhesive/FRP interface was investigated by scanning electron microscopy (SEM). The wetting property of the adhesives was dependent on the amount of aramid microfibers induced on the FRP surface. The major source of the improvement in adhesion was attributed to changes in the 成长演讲稿
