wet patch, were investigated experimental studies. The failure loads were determined with static tensile test. The fiber orientation angle of composite plates was used as 0o, 15o, 30oand 45oand the fiber orientation angle of patch was used as 0o. The patch thickness effect on the failure loads were investigated for using 2, 3 and 4 layers. The U notched plates were repaired single and double sided and the failure loads of repaired composite plates were compared with un-notched and notched (un-repaired) composite plates. The obtained results were presented as tables and graphs
