Researchers propose new technology for aviation materials to allow for adjusting their properties

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 depending on the degree of filling the polymer matrix with fibers…read more. Open Access TECHNICAL ARTICLE
