Digital image correlation, acoustic emission and in-situ microscopy in order to understand composite compression damage behavior

In this work, a description of carbon fiber reinforced polymers (CFRP) compression-damaging scenario from first micro-damages to final failure of the material and potential effect of matrix (resin) on compressive mechanical properties and the damaging scenario is given. For that, two types of CFRP with the same woven reinforcement but with different resin were tested. First, combined load compression (CLC) tests were performed and the...
