Effective Design Analysis of Fixture Development for Stitching a Sandwich Panels in an Aerospace Application

In recent years, sandwich structures have been considered as viable engineering constructions. The use of composite structures in aerospace and civil structural applications have been increasing especially due to their extremely low weight that leads to reduction in the total weight , high flexural and corrosion resistance in addition to higher transverse shear stiffness. Various combinations of core and face sheet thickness have been evaluated by many researchers worldwide. This study evaluates the aspects of putting the face sheets and core together through stitching and studies the effects and effectiveness of stitching. This paper mainly deals with design of fixture used to stitching sandwich panels, which helps to stitch different file orientations such as 900, 450, 900/450/900 and 900/450.
