To evaluate the damage of composite laminate structures which are consist of maraging steel, rubber and carbon fiber reinforced composite subjected to low velocity impact, the drop weight was used to impact the specimens and nondestructive evaluation using the C-scan was performed. After experiments, impact damages were compared with respect to various temperatures and impact energies. In case of circular plate, the damage characteristics such as delamination, matrix cracking, and fiber breakage were observed at the interface of rubber and carbon fiber reinforced composite. These results were found to be correlated with the deflection of specimen.

Damage Processes

This paper focus on evaluation of behavior, damage and failure processes occurring during the loading cycles in the carbon fiber reinforced composite by acoustic emission method. Since acoustic emission is physical phenomenon that detects the released energy in form of waves spreading through the material due to stimulation of material by external or internal stress, it is possible to evaluate complex damage and failure processes. For that purpose, the standard and open holes tensile testing specimens with different number of plies were manufactured. Selected acoustic emission parameters were correlated with data obtained from mechanical test. Linear localization method together with signal analysis using Fast Fourier transform algorithm were used as another tool for detection and evaluation of spreading damage processes inside the composite during the load. Basic damage types inside the composite material were identified by metallographic analysis using light microscopy. More complex damage processes were observed on the fracture surface using stereomicroscopy and scanning electron microscopy.
