This work shows a new way of single lap shear specimen production for hybrid metal-composite materials, which can be used to characterize process-induced interface property variations. Due to this special procedure, the specimen manufacturing can be done production-related and with a homogenization of the thermal stresses occurring in the joint area of the hybrid at each specimen. The exemption process of the specimen is kept in a minimum invasive way, not affecting the interface in the tested zone. The influence of the metal surface structure specifically created by micro form milling as well as the influence of the curing temperature on the maximum shear strength of the interface, were investigated. Finally, the driving failure mechanisms were identified and described.
