The failure pattern of prestressed AFRP sheets is fracture, but that of non-prestressed AFRP sheets is debonding. 承載力極限狀態時，預應力梁為纖維布的斷裂破壞，非預應力梁發生布與混凝土間局部脫粘破壞。
According to the results of the experiment and the nonlinear finite element analysis, we improve the form of the slabs strengthened by sheets and get a good effect. 根據試驗以及有限元分析的結果，對採用纖維布加固方形板的形式進行了改進，並取得了較好的效果。
