Adhesive interface-peeling properties of tapered double cantilever beam bonded with dissimilar material under in-plane and out-of-plane shear conditions

초록

In this study, the lightweight composite materials of carbon fiber-reinforced plastic, aluminum and aluminum foam were applied as three different bonding materials of CFRP-Al6061, Al6061-Al-form and CFRP-Al foam. Then, they were manufactured in a form of tapered double cantilever beam with adhesive interface. The adhesion-peeling properties and fracture behavior under the opening and tearing modes on the adhesive interfaces of double cantilever beams were examined through the static experiment. The results indicated that CFRP-Al6061 was most advantageous under both in-plane and out-of-plane shear conditions in terms of durability applicable to the actual design. In contrast, the Al6061-Al form specimen was most disadvantageous. Through these experiments, this study aimed to investigate the adhesion-peeling properties and fracture behavior of the bonded dissimilar materials having the adhesive interface. The results can be effectively used at developing lightweight composite materials and the bonding technologies for other materials.
