EFFECT OF TRANSVERSE DAMAGE ON COMPRESSIVE STRENGTH IN FIBER DIRECTION FOR CFRP
Résumé
The influence of transverse damage on compressive strength in fiber direction for woven CFRP materials is investigated by an experimental approach. Several experiments are proposed in order to show the loss of strength when material is damaged. The first study focuses on sample validation to exclude buckling collapse. Then damaged tubes in torsion are studied in pure compression test. The tests are followed by digital image correlation to analyze structural effects affecting the material characterization. It is finally shown that the transverse damage affects the mechanical performance in compression.
