Phys.org September 19, 2022 Most of the carbon fiber composites used currently are based on epoxy resin and other non-melting, insoluble materials that are not recyclable. Researchers in Russia have created a new composite material based on engineering thermoplastic polymers and carbon fiber. For matrix they used polyethersulfone powder which has excellent mechanical properties and resistant to high temperatures, steam, and various chemicals. Unlike epoxy it is recyclable. They determined the optimal content of carbon fibers for airborne composites based on polyethersulfone to be 60–70% of the total weight of the structure. The properties of the material can be adjusted […]

Multifunctional carbon fibres enable massless energy storage
Physics World September 7, 2018 Carbon fibres’ microstructural designs have been generated to realise a targeted mechanical property. An international team of researchers (Italy, Sweden, France) compared the microstructure and electrochemical performance for two types of commercial carbon fibre, middling mechanical properties and the hardest hitters in terms of structural strength. They found that the intermediate strength carbon fibres were much less organised but still had such high mechanical properties that even smaller crystals might still get good mechanical properties. According to the researchers exploiting the electrochemical properties of carbon fibres could drop device masses by as much as 50%… […]
