Improving Interfacial Interactions of CF/PEEK Composites with Sulfonated Polyether Sulfone
Tianning Ren,Guangming Zhu,Xiaoming Ren,Renjie Tian,Ben Li 한국섬유공학회 2021 Fibers and polymers Vol.22 No.1
Due to the limitation of surface inertness and wettability of carbon fibers (CF), the adhesion between Poly(etherether-ketone) (PEEK) resin matrix and CF is poor, which reduces the mechanical properties of CF/PEEK composites. Inorder to improve the interfacial performance between PEEK matrix and carbon fiber fabric, sulfonated-polyether-sulfone (s-PSF) was coated as a sizing agent on the surface of the carbon fiber to construct CF/PEEK composite interface. On one hand,the formation of hydrogen bonds between s-PSF and activated CF increases the adhesion between s-PSF and fibers. On theother hand, Good compatibility between S-PSF and PEEK, which improves the interface performance between PEEK andCF. The results showed that the mechanical properties and interface properties of CF/PEEK composite prepared by modifiedCF were improved to some extent. The flexural strength, flexural modulus, impact strength and interlaminar shear strength ofthe materials were increased by 57.5 %, 16.7 %, 44.2 % and 39.7 %, respectively. By introducing s-PSF as sizing agent intoCF/PEEK composite interface, the comprehensive properties of the material were effectively improved.
