The automated pultrusion process fabricates continuous glass or carbon fiber-reinforced, constant cross-section profiles with consistent, uniform properties.  For the brace, Avient's engineering team developed and analyzed three options: a unidirectional, hybrid carbon and glass fiber profile; a unidirectional carbon fiber profile; and finally, a profile made with both a unidirectional carbon fiber and a transverse engineered fabric, which had the advantage of minimizing any potential cracks from propagating.

Its low glass transition temperature delivers excellent flexibility, good gel condition, and processability. Light-weighting solutions that replace heavier traditional materials like metal, glass and wood, which can improve fuel efficiency in all modes of transportation and reduce carbon footprint

Additionally, as part of the TCC conference program, Jonathan Spiegel, Senior Engineer of Advanced Composites at Avient, will co-present with Benjamin Willis, Director of Product Development at Re:Build Manufacturing, on the Manufacture of Sandwich Structure of Recycled HDPE and Continuous Glass Reinforced HDPE Composite using Extrusion-Compression Molding.  Light-weighting solutions that replace heavier traditional materials like metal, glass and wood, which can improve fuel efficiency in all modes of transportation and reduce carbon footprint
