Damage Investigation on the Carbon Tows during Rewinding and Braiding Processes

During the manufacturing process, fibrous materials used in composite reinforcements are subjected to many sources of damage that must be managed if best possible quality is reached for final product. More specifically, carbon fibers subjected, during reinforcement manufacturing, friction with mechanical components and other tows excessive tensile loads due specific configurations required by textile devices, which results degradation affects their properties those products. While studies have focused on tow weaving roving control post-braiding steps, such as rewinding or braiding processes, less studied literature. In this study, an experimental approach was developed quantify inflicted 12 K processes using image analysis software. Based these images, a criterion defined influence parameters associated tows. stage, process significant, but (linear density tenacity) were little-modified. On hand, great tension applied experimentally demonstrated, both may resulted loss tenacity up 27%.
