ADHESIVE SELECTION OF COMPOSITE MATERIAL JOINTS
Keywords:
COMPOSITE MATERIAL, strength and stiffness, performanceAbstract
This study focuses on the adhesive selection process for composite material joints, with the goal of identifying the most suitable adhesive for a given application. Two types of composite materials, carbon fiber-reinforced polymer (CFRP) and glass fiber-reinforced polymer (GFRP), were considered for the study. A total of six different adhesives were evaluated, including epoxy-based, polyurethane-based, and cyanoacrylate-based adhesives. The adhesives were tested using lap shear and tensile tests, and the results were used to evaluate their mechanical properties, including strength, stiffness, and failure mode. The results showed that the epoxy-based adhesives generally exhibited the highest strength and stiffness, while the cyanoacrylate-based adhesives exhibited the lowest strength and stiffness. The study also investigated the effect of various factors, such as surface preparation and curing conditions, on the adhesive joint performance.
