EFFECT OF TRANSVERSE DAMAGE ON COMPRESSIVE STRENGTH IN FIBER DIRECTION FOR CFRP

Abstract

International audienceThe influence of transverse damage on compressive strength in fiber direction for woven CFRPmaterials is investigated by an experimental approach. Several experiments are proposed inorder to show the loss of strength when material is damaged. The first study focuses on samplevalidation to exclude buckling collapse. Then damaged tubes in torsion are studied in purecompression test. The tests are followed by digital image correlation to analyze structuraleffects affecting the material characterization. It is finally shown that the transverse damageaffects the mechanical performance in compression
