Compressive fatigue behavior of low velocity impacted and quasi-static indented CFRP laminates

The compression fatigue behaviors of CFRP laminates with impacted or quasi-static indented damage for two material systems, CCF300/QY9511 and CCF300/5428, were compared in this paper. The same surface damages, characterized by dent depth, were induced by low velocity impact (LVI) or quasi-static indentation (QSI) tests for the CFRP laminates. Using visual observation, C-Scan and thermal de-ply experimental measure methods, the surface damage and...
