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.
Solvay has signed a ten-year agreement for the supply of composites and adhesives to be used across Bell's military and commercial rotorcraft programmes, including the Bell 429, 407, 505, 525, V-22, and UH-1.
SGL Carbon and Fraunhofer IGCV have officially opened the Fibre Placement Centre (FPC) at SGL's site in Meitingen, Germany. Compositence, BA Composites and the Chair for Carbon Composites at the Technical University of Munich have also joined the alliance, and Coriolis Group and Cevotec are planning to come on board as partners.
With the aim developing a broader platform for additive manufacturing (AM) technologies, the University of Exeter, UK, and Victrex, have formed a strategic partnership to introduce next-generation polyaryletherketone (PAEK) polymers and composites while improving the performance of the underlying AM processes.
