Abstract
This presentation introduces technique and some applications where fine fibers were previously added into matrix of fiber reinforced composites. The fatigue life was dramatically increased 10-100 times by the addition of fine fibers into the matrix in contrast to the static case. Those effects in improvement of mechanical properties of the textile carbon fiber composite were explained by the prevention of interfacial crack propagation with large resistance between carbon fiber bundles in Mode-II and modified matrix around the texture points where comparatively large strain energy would be released, if the epoxy matrix was adequately modified with the fine glass fibers.
