Fatigue behavior and modeling of chopped carbon fiber reinforced sheet molding compound composites

Abstract

The quasi-static and fatigue behavior of chopped carbon fiber reinforced sheet molding compound (SMC) composite was investigated. The microstructure of material was inspected by X-ray Computerized Tomography (XCT) and the fiber orientation distribution was analyzed. Quasi-static tensile test was performed on specimens with different gauge length to study the size effect on mechanical properties and digital image correlation system was applied to record the strain distribution. The fatigue behavior of material was evaluated
