Optimized Preforms for High Performance Long Fiber Reinforced Thermoplastic Tubing
Production of hollow thermoplastic composite parts require placement of fiber materials in various formats such as individual rovings, unidirectional tapes, and woven or non-woven fabrics. Placement of those reinforcement fibers and other materials is usually by methods that range from manual to highly automated tape laying equipment. The process described here is a unique method suitable for the many small to medium sized hollow shapes such as in specialized tubing required for many applications. The method and solution described here is referred to as the LEAF placement system and is a process where fiber materials and polymers are metered into position by use of an automated process. Fibers are controlled and placed using the following variables of layering, spacing, angle variation, and length to create the fiber architecture and design of the composite part. The process provides ways to accurately control fiber placement allowing predictable mechanical properties. The information to follow will describe this process, its benefits, and applications of this method.
