エポキシ系接着継手の高温強度特性および高温エージングの影響

抄録

Lap joints were prepared using epoxy adhesive and aluminum plates, and the properties of high-temperature strength were studied. Tensile test and aging test were performed at high temperature. The effects of test temperature were systematically investigated. The obtained conclusions were following. When the specimen was exposed at temperature of 135℃, the strength decreased significantly. The adhesive changed its chemical structure by oxidation. The relationship between test temperature and tensile strength could be expressed using the Arrhenius equation.
