A Simple Approach to Modeling the Failure of Flawed Polyester Textile with the Application of the Concepts for Fracture Mechanics

Abstract:

A widely used organic polymer textile material, which is made of polyester fibers and then cured in the resin afterwards to fix the original pattern of the textile, is used to study the flaw’s influence in the mechanical properties as well as its influence in the failure behavior of the textile. This kind of textile is preferably applied and acts as the re-enforcement part or component in the composite design or composite manufacturing. To mathematically and theoretically analyze the relationship between the mechanical behavior of the polyester textile and the flaw within the material, a model based on the fracture mechanics is proposed to explain the experimental results from the mechanical tests of polyester textile specimens.
