The objective of this project is to investigate tbe effectiveness of patch surface area and shape on flexural strength of the composite material. The material under study is glass/polyester composite and it is prepared by using hand lay-up technique. The patch shapes under investigation are square and octagonal. Five different patch surface areas were prepared varying from 2mm until 8mm. The parent laminates were damaged by drilling a standard 8.42mm diameter hole in the middle of it as artificial damage. A piece of composite material is tben attached to the original primary composite structure using an adhesive to restore the original performance of tbe composite. The flexural test is conducted under ASTM Standard D790 by using three point loading system. However, from the results obtained from the test, it was found that the flexural yield strength value is more relevant to be calculated rather than flexural strength due to the constraints of the test specimen.
