Abstract: Fibre-reinforced polymers (FRPs) are increasingly being used as reinforcement in new concrete structures and as strengthening materials for the rehabilitation of existing concrete structures.The main advantages of FRPs are their light weight, high strength, and non-corrosive features. The research presented in this paper is an effort to understand the interlaminar fracture behaviour of glass/epoxy composite laminates after acid treatment of varying dilution. This study uses 3-point flexural test to qualitatively assess such behaviour for 50 weight percentage of E-glass fibres reinforced epoxy composites after acid treatment. The specimens were tested at 2 mm/min and 500 mm/min crosshead speed to evaluate the sensitivity of mechanical response during loading at these conditions. The mechanical performances of the laminated specimens treated in acid solution of different concentration were compared by using SEM photographs. Phenomenological behaviour of these materials may be attr...
