Failure Analysis in a Multilayerd Glass Fiber Reinforced Polyester Composite Plates under Flexural Loading

Abstract

The usage of laminated glass fiber reinforced polyester composites in aerospace applications helps to reduce overall weight of the aerospace structures. The flexural strength of the laminated glass fiber reinforced composites becomes more important when they are employing for aeroplane wings. In this work, a laminated glass fiber polyester composite with two distinct sets of six different woven lamina stacking sequences is manufactured via hand layup technique. The effect of stacking sequence over the total ply failure load are investigated through universal testing machine. Finally, the progressive failure of the lamina in composites is also examined using ANSYS software.
