Abstract: A moldable pellet used for making high impact, non-abrasive recyclable structural composites consisting of a thermoplastic polymer or polymers, with or without fillers and additives, and a synthetic cellulosic fiber in yarn or tow form such as Rayon or Lyocell. The concentration of cellulose fiber within the pellet may vary from approximately 2–80 percent by weight or higher. This moldable pellet is suitable for molding in current molding applications such as, but not limited to, injection molding, extrusion compression molding, and compression molding.
