In this paper, the fatigue response of a foam core sandwich composite with unsymmetrical hybrid faces has been investigated. The sandwich laminates were manufactured using the same method for a corresponding selected element in a real composite structure.Two similar woven E-glass fibers (designated by G1\& G2), following unidirectional carbon fibers(C) with Epoxy resin, were used as the face sheet over a PVC foam core. The lamination sequence and angles are, as follows, respectively: [G1/C/C/C/G2/ Foam /G2/C/C/G1], [0/0/0/0/
for the laminate, two of them were nucleated and grown in the foam core, first in thickness and then parallel to the length
of the gauge. By increasing the overall stress level, the parallel cracks were shortened.
