Pultrusion Technique for Braided Fabric Reinforced Thermoplastic Composite Tube

Papers # 2010 Vancouver

Pultrusion process is one of the composite production methods that have been used for mass production of uniform profiles. However, there are two problems that are commonly found in pultrusion products; one of which is its anisotropic mechanical properties. This anisotropicity stems from the alignment of reinforcements in the longitudinal direction during the pultrusion process. The other problem is the difficulty in recycling since thermosetting resins are typically used as the matrix resin for these composites. Therefore, a combination of braiding and pultrusion techniques as well as the usage of thermoplastic resins to produce continuous fiber reinforced thermoplastic composite profiles was proposed. In this study, L-shape pultrusion of thermoplastic composite was fabricated with braiding technique. Relationship between molding speed and impregnation state, mechanical property of the composites was discussed.
