A method for preparing a carbon fiber reinforced pantograph carbon slide based on 3D printing, comprising the following steps: S1, preparing printing materials, including printing paste and carbon fiber cloth, and the printing paste includes thermosetting phenolic resin particles, graphite powder, and nitrile rubber Particles, copper nanoparticles, reinforcing fibers and photosensitive resin; S2, construct a three-dimensional model and input it into the 3D printing editing software, and set the 3D printing process parameters; S3, set the temperature control device and temperature monitoring above the molding substrate of the molding cylinder device, seal the working area of the 3D printing equipment and fill it with argon gas for protection; fill the printing slurry layer by layer in the forming cylinder and lay carbon fiber cloth, and start to light-cure and form the 3D printed carbon skateboard blank; S4, the carbon skateboard blank in turn After degreasing treatment, roasting treatment, washing and drying, preheating and copper immersion treatment are carried out to complete the preparation. The method can realize rapid preparation of the carbon slide, has high raw material utilization rate, and the prepared carbon slide has excellent comprehensive performance. |
