| Research Abstract |
In the structural members strengthened by bonding carbon-fiber reinforced polymer, CFRP, thermal stresses are introduced when the temperature changes because the linear thermal expansion coefficients of conventional structural materials, e.g. steel or concrete, and CFRP are mismatched. With this in mind, we proposed a technique to reduce the thermal stress in structural members strengthened by CFRP, which involves bonding aluminum alloy plates with CFRP. The thermal test results showed the effectiveness of proposed method for reduction of thermal stress in structural members. Furthermore, the evaluation method for debonding of CFRP from structural members was proposed.
