Description

technical field [0001] The invention relates to a carbon fiber reinforced polyetheretherketone paper-based friction material and a preparation method thereof, belonging to the technical field of composite materials. Background technique [0002] Friction materials are a very important class of materials in the national economy, and are widely used in transportation, chemical machinery, aerospace and other fields. Friction materials use friction to transmit torque and brake during the working process, and are important materials to ensure the smooth operation and safety performance of automobiles. For a long time in the past, the friction materials most commonly used in industry were mainly traditional friction materials such as metals, ceramics and cement substances. However, as the industry's requirements for the comprehensive performance of friction materials are gradually increasing, traditional friction materials gradually show limitations such as poor deformation abili...
