Composite has been the main material that’s applied in many forms of industries, such as airplane, aircraft, boats automotive industries even to sport goods. Adhesive joining is one of the methods for joining 2 materials together and has the advantage of lighter weight than welded components or the use of nut and bolt. Adhesive is used in this study where aluminium and GFRP is bonded. Non-heated adhesive and heated adhesive conclude where the heated adhesive is heated under the temperature of 100°C for one and a half hour. The hardness of the heated specimen shows higher value with 58.6 HA than non-heated adhesive with 53.05 HA. Overall, better performance is obtained from the non-heated specimen where the average shear strength of single lap joint adhesive is 11.4 Mpa and 6.0 Mpa for the heated adhesive. The double lap joint adhesive for the non-heated specimen also performs better in terms of shear stress with the average of 13.1 Mpa and 11.4 Mpa for the heated adhesive. The failure mostly is cohesive failure, but double lap joint specimen shows an unusual behaviour and graph because the adhesives alternately broke on their top and bottom surfaces.
