Photoelastic Analysis of Stress Transfer From Matrix to the Fibre Through an Interphase in Compression
Year: 2007
Type: conference-paper
Abstract: The objective of the current work is to examine the stress transfer in a (a limiting design parameter in aircraft composite structures) Glass Fibre Reinforced Polymer (GFRP) composite taking into account the fibre/matrix interphase in compression, observe the stability of the interphase region during compressive loading and study the transfer of stress from matrix to the fibre through this region. In this study, a GFRP composite system is used. The composite material is made of a coated glass fibre (with a low modulus, “LM” and high modulus “HM” interphase) as a reinforcement surrounded by a polymer matrix. A finite element analysis for a single short fibre with two different Interphases (LM and HM) embedded in a block of polymer matrix is performed and interfacial shear stress results are compared to experimental data (photoelasticity) and existing analytical solutions.
