Abstract

The orthotropic fiberglass composites are of great interest in different contemporary industrial fields. During their use and under the effect of external stresses, such as heat and mechanical stresses, these materials can undergo structural changes that can alter their physical and mechanical properties. Analysis of the results of different characterization methods such as tensile test with extensometer and also digital image correlation by 7D software allows the understanding of degradation mechanisms mainly based on changes in internal structure, geometry, boundary conditions and external constraints that are applied
