Application of Residual Fibers of Polyethylene Terephthalate - PET in Structural Composites: A Systematic Review

Abstract

Fiberglass is the most commonly used material in the manufacturing process of wind turbine components, as it meets the basic requirements of the final product. However, as the market for wind turbines expands, industries must keep up with the demands of increasing blade efficiency at a reduced cost. As a replacement for fiberglass, poly (ethylene terephthalate) - PET textile fiber is an option, which has better tensile strength, elongation rate, and low density. However, it has low wettability and poor interfacial bonding with resin matrices. This study aims to perform a literature review of existing scientific studies using PET fiber from the tire industry or not applied as reinforcement in structural composites.
