Abstract

In the present study, the experimental investigation of the repair of the Al 2024 T3 plate with edge and center crack by Carbon fiber-reinforced polymer (CFRP) patch under tensile loading is carried out. The present work is carried out in two parts. In the first part, the fracture analysis of isotropic and CFRP plates with edge crack under tensile loading is carried out. Where the comparative study of Al plate and CFRP [Unidirectional (UD) and Bidirectional (BD)] is presented for the selection of proper patching material. In the second part, the repair of the cracked isotropic plate by BD CFRP patch is presented. In this present work, it is observed that CFRP (BD) patch is suitable for the crack repair of the Al plate. The crack growth does not take place from the initially generated crack in the repaired plate under tensile loading and the maximum peak load in the edge and center cracked repaired plate is increased by 26% and 16% respectively as compared to the unrepaired plate.
