Carbon/carbon composite material brake disc and preparation method thereof
The carbon/carbon composite material brake disc comprises a brake disc base body and a plurality of groove-shaped clamps, a plurality of key grooves are evenly formed in the peripheral wall of the brake disc base body, the groove-shaped clamps are fixed in the key grooves of the brake disc base body respectively, and the groove-shaped clamps are matched with the key grooves; the brake disc base body comprises multiple layers of carbon fiber cloth which are arranged in the radial direction, and further comprises carbon fiber lines which penetrate through the multiple layers of carbon fiber cloth in the circumferential direction. The groove-shaped clamp comprises 20-40% of first two-dimensional carbon fiber, 20-40% of second two-dimensional carbon fiber, 20-40% of matrix carbon and 5-30% of carbon filler; the density of the first two-dimensional carbon fibers is 1.6-1.8 g/cm < 2 >, the density of the second two-dimensional carbon fibers is 0.8-1.0 g/cm < 2 >, and the matrix carbon is generated by carbonizing resin or asphalt. The groove-shaped clamps are fixedly connected to the brake disc base body, so that the service life of the brake disc is prolonged, the high-temperature resistance of the brake disc is improved, the service life is prolonged, and the wear resistance of the brake disc is improved.
一种碳/碳复合材料刹车盘及其制备方法，包括：刹车盘基体和若干个槽型夹，刹车盘基体外周壁均匀设置有若干个键槽，若干个槽型夹分别固定在刹车盘基体的若干个键槽内，槽型夹与所述键槽相适配；刹车盘基体包括多层碳纤维布，多层碳纤维布径向排列，还包括碳纤维线，碳纤维线周向贯穿多层碳纤维布；槽型夹包括第一二维碳纤维20‑40％，第二二维碳纤维20‑40％，基体碳20‑40％，碳填料5％‑30％；第一二维碳纤维的密度为1.6‑1.8g/cm2,第二二维碳纤维的密度为0.8‑1.0g/cm2，基体碳由树脂或沥青碳化生成。本发明通过在刹车盘基体上固定连接若干个槽型夹，延长刹车盘的使用寿命，提高刹车盘的耐高温性能、延长了使用寿命和耐磨性。
