During the manufacturing process, fibrous materials used in composite reinforcements are subjected to many sources of damage that must be managed if best possible quality is reached for final product. More specifically, carbon fibers subjected, during reinforcement manufacturing, friction with mechanical components and other tows excessive tensile loads due specific configurations required by t...

The present paper investigates the failure of SiC and alumina-fiber-reinforced minicomposites in relation to strength distributions filaments, behavior reinforcing dry tows. data are measured on single-filament, dry-tow minicomposite specimens using tensile tests under commonly used test condition strain-controlled loading. Pertinence normal distribution strengths at different length scales is ...

This article concerns the experimental and numerical study of post-impact damage propagation in thin carbon/epoxy 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 monitoring is based on Digital Image Correlation RX tomography. influence energy loading studie...
