Dynamic Debonding Strength of Fiber Glass Composite

A laminated composite may fail by various mechanisms: debonding, delamination, fiber fracture, matrix cracking, and fiber buckling. The fiber fracture possess the greatest threat the structure integrity. However, the progressive debonding often increases the load sustained by the fiber; therefore, it may promote the fiber fracture. It is clear that data of the debonding strength are crucial. Unfortunately, the experiment for the purpose is often difficult particularly in a high-strain rate case. In this paper, we present an experimental technique to obtain the mechanical properties of the debonding in the high-strain rate case.
