Plasticomp LLC has announced the successful application of 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 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 4-6msi,' said Raj Mathur (PhD), Plasticomp business manager for advanced materials and processes.
'Through tailored fibre weight-fractions (40-50 per cent) 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.
The materials are targeted for metal replacement in military, industrial and aerospace applications.
In addition to light-weighting, the materials can also be customised for EMI shielding and thermal properties.
