Blister tests on thin-walled composite structures at different temperatures
Source abstract
Abstract
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.
