Introduction Compared with more traditional materials such as metals ceramics and polymers fiber reinforced composites have several specific features such as high stiffness and strength to weight ratio excellent corrosion resistance and ability in providing both mechanical as well as functional properties. The most common failure mode of this high performance laminated material is delamination as a consequence of low velocity impact and or cyclic loading during .
