▎ 摘　　要

NOVELTY - Preparing MXene graphene synergistically reinforced high-content carbon fiber reinforced polyether ether ketone (PEEK)-based composite material, comprises (i) pretreating continuous carbon fiber felt; (ii) soaking the pretreated continuous carbon fiber felt in a PEEK-1,3 dioxolane solution dispersed with MXene for sizing, and then hydrolyzing to obtain carbon fiber deposited with MXene (M-CF); soaking the remaining part of the pretreated continuous carbon fiber felt in PEEK-1,3 dioxolane solution for sizing, and then hydrolyzing; and subjecting the carbon fiber after the hydrolysis treatment to graphene spraying treatment to obtain the carbon fiber sprayed with grapheme (G-CF); (iii) paving multiple layers of the M-CF, multiple layers of the G-CF and multiple layers of PEEK films; (iv) heating and pressing the layered structure to obtain final product, where amount of carbon fibers in the PEEK-based composite material is 60-65 wt.%. USE - The method is useful for preparing MXene graphene synergistically reinforced high-content carbon fiber reinforced polyether ether ketone-based composite material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for MXene graphene synergistically reinforced high-content carbon fiber reinforced polyether ether ketone (PEEK)-based composite material prepared by above method.
