PlastiComp LLC (Winona, Minn.) announced on Oct. 6 that it has successfully applied its long-fiber thermoplastic (LFT) technology to high-temperature polymers such as PPS, PES, PEI, and PEEK reinforced with carbon fiber. 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 fibers with high-temperature polymers, and subsequent consolidation into molded parts yield tensile modulus values of 4-6 Msi,” explains Raj Mathur, Ph.D., PlastiComp business manager for Advanced Materials and Processes. “Through tailored fiber weight-fractions [40 to 50 percent] and long fiber-length retention in the molded 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 fiber-resin combinations. It can be seamlessly integrated with existing production methods such as injection and extrusion-compression molding 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.
