In this study, peel tests were carried out according to ISO 8510-2 to examine the adhesion performance of fabric reinforced thermoplastic polyurethane (FRTPU) and AA6062 aluminium alloy. For this purpose, in addition to thermoset-based epoxy adhesive, thermoplastic-based (TPU) adhesive was used with the aim of maximizing interface compatibility with FRTPU. When the mechanical properties of the TPU-based bulk adhesive were determined by performing the tensile test, lower results were obtained in terms of tensile strength compared to the epoxy adhesive, while a significant increase in the elongation value was observed. According to the peel test results, the maximum load on adhesive joints bonded with thermoplastic-based adhesive was measured as 56.2 N, while the maximum load on joints bonded with epoxy was measured as 101.8 N. When the toughness values are calculated, the toughness value of adhesive joints bonded with TPU-based adhesive is 80% lower than the joints bonded with epoxy. When the damage surfaces were examined, it was determined that the target of compatibility with FRTPU adherend was achieved in the use of TPU-based adhesive.
