Experimental Determination of Flexural Strength of Glass Fiber Reinforced Composite Laminates

Aerospace industry is in need of material which has high, strength to weight ratio. Before using a material for aerospace application it is necessary to test that material as per ASTM standard. The continuous and chopped fiber composite beam was fabricated at various thicknesses (3 and 4 mm) by using the Hand lay-up technique. Many structures are often prone to bending loads, which can result in serious damage. Therefore, for structural integrity, structures must be efficient to resist bending. Flexural loading causes stresses in the composites, which vary through the thickness according to fibers so determine the flexural strength of glass-epoxy composite beam. The glass epoxy beams are cut as per the ASTM D7264 for flexural test. The structural parts subjected to bending loads causing flexural stress. The present study aims at investigating the flexural parameters of Glass-Epoxy composite beam when subjected to static flexural loading. The flexural parameters are determined by flexural test on in specimen. The loads Vs deflection graphs are plotted from which flexural strength for glass - epoxy composite beam is determined.
