Abstract

Composite sandwich structures fail by various means such as de - bonding, breaking of core etc. which can be minimized by stitching and z - pinning technique, but these techniques have their own limitations. To improve the parameters that the above mentioned methods cannot provide, a new method called as winding on the sandwich pa nel is introduced. In this paper the comparison of these methods with the new technique used on standardized sandwich panel is portrayed with differences in properties such as Bending strength, flexural rigidity and strength to weight ratio. A 0.8mm diamet er glass fibre yarn is used for the winding and stitching techniques on the sandwich panel. The face sheet used is E - glass/epoxy and the core is PVC Divinycell H80 foam. All Tests are carried as per ASTM standards .
