The usual method of strengthening concrete structures with fiber reinforced plastic (FRP) is to bond FRP sheets on the surface of concrete, so the bond strength between concrete and FRP sheets is a key issue which affects strengthening.

• 纤维增强塑料(简称FRP)加固混凝土结构通常是将其粘贴在混凝土的表面；因此FRP材料与混凝土结构之间的粘结性能成为影响加固效果的关键因素.
