Thermoplastic Composites — Evolution & Trends — Let's Get Started!

SpecialChem / Donald Rosato & Don Rosato – Nov 21, 2012

Composites are engineering materials made from two or more constituent materials, matrix and reinforcement, that remain separate and distinct on a macroscopic level while forming a single component.

Long Fiber Reinforced Thermoplastics (LFRTs) have excellent mechanical properties and stiffness-to-weight ratio, which is of great interest to the automotive industry. They are ideally suited for applications requiring high strength/stiffness, excellent low-temperature impact properties, and low coefficient of thermal expansion (CTE).

'Curv' novel PP (polypropylene), manufactured by Propex Fabrics, combines the high performance of a fiber reinforced composite with the versatility of 100% thermoplastic. Milliken is producing TEGRIS (moldable fabric technology) sheet stock using PURE technology through a licensing agreement with Lankhorst-Indutech. A new type of high-loft, lightweight GMT (glass mat thermoplastic) formable sheet made with basalt fibers derived from volcanic rock has been developed by Hanwha Azdel.

HPPC, high-performance (thermo) plastic composite, (IXIS) is a unique, reinforced thermoplastic sandwich construction for horizontal automotive body panels. The high-performance composite technology (HPPC) used in body paneling in the Volt and QuarmaQ Concept cars featured a sandwich of glass mat and thermoplastics made with Valox iQ, and Xenoy iQ based on polybutylene terephthalate (PBT) derived from regenerated post consumer polyethylene terephthalate.

SymaLITE underbody shields are compression moldable light weight composites from Quadrant Plastic Composites based on PP and specialty oriented glass fibers. VolcaLite is...
