Variation of the impact characteristics such as maximum contact load, maximum deflection, maximum contact time, absorbed energy are depicted in the figures. The results showed that PVDF nanofibers are not a good choice for toughening epoxy and improving impact damage resistance of GFRP. | Impact response of glass epoxy laminate interleaved with nanofibrous mats Engineering Solid Mechanics 1 2013 85-90 Contents lists available at GrowingScience Engineering Solid Mechanics homepage esm Impact response of glass epoxy laminate interleaved with nanofibrous mats H.

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 .
