Experimental and analytical testing of a composite laminate material G10/FR4 under cyclic loading

Abstract

The objective of this work is to predict the deterioration and failure of composites under essentially any type of loading—constant, variable, bending, torsion, tension, compression, or others. G10/Fr4 is a thermosetting industrial fibre glass composite consisting of a continuous filament glass cloth material with an epoxy resin binder. It was matrix formed and layer by layer formed with glass fibre and epoxy resin to study different mechanical properties. Initially experimental and computational studies were performed on matrix formed sample to characterize tensile and compression properties of thermosetting fibre glass composite. When the results of computational and experimental methods were compared, similar values are obtained. Other sample of G10 FR-4 made by layer by layer forming with glass fibre and resin sample is used for bending test. Also, tensile, compression and bending loads are applied repeatedly many number of times to predict the fatigue life of material. Both experimental and computational tests were conducted and compared. We get similar tensile, compression, and bending properties in experimental and computational method.
