High Temperature Thermoplastics Achieve Higher Performance

23 October 2008

PlastiComp has applied its long fibre thermoplastic (LFT) technology to high temperature polymers such as PPS, PES, PEI, and PEEK reinforced with carbon fibres.

These new composite materials have potential for further penetration into traditional metal applications requiring very high modulus.

“Our proprietary technologies for the hot melt impregnation of the reinforcing fibres with high temperature polymers, and subsequent consolidation into moulded parts yield tensile modulus values of 4-6 Msi,” explains Raj Mathur (PhD), PlastiComp Business Manager for Advanced Materials and Processes. “Through tailored fibre weight-fractions (40-50%) and long fibre-length retention in the moulded parts we have attained a balance of properties for mechanical performance at elevated temperatures.” According to laboratory testing, high-temperature polymers achieve higher performance with the PlastiComp LFT process.

“After several years in composite applications at prior technology firms, I am excited about the capabilities of the PlastiComp process to bridge the gap between composites and metals. It is well suited to a wide range of fibre-resin combinations. It can be seamlessly integrated with existing production methods such as injection and extrusion-compression moulding and filament winding.”

PlastiComp’s new high-performance materials are targeted for metal replacement in military, industrial, and aerospace applications. In addition to light-weighting, the materials can also be customized for EMI shielding and thermal properties.
