A study on the fracture characteristics of tapered double cantilever beams made of heterogeneous composites with adhesive interfaces
Journal of Mechanical Science and Technology(2021)
Abstract
In this study, CFRP and aluminum properties were investigated by carrying the static experiment on the shape-dependent bonding structure, and designed tapered double cantilever beam (TDCB) made of heterogeneous composites with the angle of inclination as a variable. The results showed that the maximum reaction force generated was the greatest when the slope angle was 8°. When the specimen is designed using heterogeneous composite materials, the maximum reaction force of the specimen with an inclination angle of 10° is slightly lower than that of a specimen with inclination angle of 8°. However, these results show that it is possible to obtain a design advantage by supplementing the shape. The results of this study can be used as basic data for the safe design of mechanical structures using composite materials and heterogeneous composites.
