Study of post-impact behaviour of thin hybrid carbon/epoxy and glass/epoxy woven composite laminates under fatigue tensile loading – Part I : Experimental study

This article concerns the experimental study of post-impact damage propagation in two thin carbon/epoxy and glass/epoxy hybrid woven composite laminates loaded fatigue tension. Low velocity normal drop weight impact tests are first performed. Post-impact tensile then carried out. They controlled displacement. The is monitored by RX Tomography Digital Image Correlation. influence energy displacement level variation on studied. also conducted mono-material order to understand phenomenons which occur laminates. Two different behaviours depending configuration obtained. mainly influenced carbon plies orientations. Levels loading energies have an initiation speed. scenario when delamination occurs. stacking sequence change position laminate leads a behaviour.
