Abstract
The paper presents the results of a thorough study of internal structure and mechanical behavior of non-crimp 3D orthogonal woven carbon/epoxy composites. The following parameters and phenomena are investigated:
-internal geometry of the reinforcement: shape of the yarns, waviness, dimensions and shape of the cross sections, and fiber volume fraction inside the yarns;
-stiffness and strength of the composites;
-non-Hookean effects (stiffening of the carbon fibers with increasing strain)
-damage initiation and development monitored by means of acoustic emission
-crack morphology at different stages of loading studied with X-ray and optical microscopy;
-tension-tension fatigue: S-N curves and damage development with increasing number of cycles.
