Long and short fiber reinforced thermoplastics provide outstanding design flexibility but offer varying performance ranges depending on their specific material composition. The continuous fiber reinforcement provides strong and stiff material performance, while the thermoplastic resin matrix enables design flexibility through post-forming. These materials can be formed into multi-ply laminates to offer off-axis performance, post-molded into complex shapes, and overmolded with traditional thermoplastics to provide localized reinforcement in specific part locations.
