Kurzbeschreibung (Abstract)
Blister tests are widely used to characterize adhesives on substrates. In this paper, pressurized blister tests are performed at different temperatures between −40 C and 180 C with two different glass fiber-reinforced plastic laminates. The paper examines the influence of surface pretreatment and geometric features of the substrate. The resulting burst pressures vary between 1 bar and 150 bar. Our studies show that the main influences on burst pressures at high temperatures are glass-transition temperature and storage modulus, and at low temperatures brittleness of the epoxy. Surface pretreatment of corundum blasting results in the highest burst pressures. While the gap width has a big impact on burst pressures, gap spacings show little influence.
