Improving the interface of carbon‐fibre‐reinforced poly(ether‐ether‐ketone) composites with fibre surface coating: a review

Abstract

As a high‐performance thermoplastic polymer, poly(ether‐ether‐ketone) (PEEK) has excellent thermal stability and mechanical properties; it is widely used in the aerospace field. However, PEEK has high viscosity, high processing temperature and poor fluidity in the molten state. In preparing carbon fibre (CF)/PEEK composites, poor impregnation performance will occur, resulting in high porosity and poor mechanical properties of the CF/PEEK composites. This mini‐review focuses on improving the interface of the CF/PEEK composite by coating the CF surface and introduces the preparation of CF/PEEK composites by coating CF with a resin‐based sizing agent, a mixed sizing agent and nanoparticles. Meanwhile, the properties of CF/PEEK composites prepared by different coating methods are compared. © 2022 Society of Industrial Chemistry.

Effect of polyphenylene sulfide sulfone sizing agent on interfacial, thermal, and mechanical properties of carbon fiber

“…7 This challenge has led to the development of sizing agents that are appropriate to the processing temperature of high-performance thermoplastic resins. [8][9][10] Among them, PPS and poly (aryl-ether-ketone) (PAEK) are two extensively utilized sizing agents. Since PPS and PAEK are almost insoluble in organic solvents at room temperature, they require modification before they can be utilized as sizing agents.…”

“…The epoxy resin sizing agent commonly used in commercial CFs is unable to withstand such high temperature, resulting in the failure of the interface layer of the composite material 7 . This challenge has led to the development of sizing agents that are appropriate to the processing temperature of high‐performance thermoplastic resins 8–10 . Among them, PPS and poly (aryl‐ether‐ketone) (PAEK) are two extensively utilized sizing agents.…”
