Carbon-ceramic brake disc with matrix containing short carbon fibers and preparation method of carbon-ceramic brake disc
The invention provides a carbon-ceramic brake disc with a matrix containing short carbon fibers, the carbon-ceramic brake disc with the matrix containing short carbon fibers comprises carbon fibers, silicon carbide, monatomic silicon and residual carbon, the carbon fibers comprise skeleton carbon fiber bundles and filling carbon fiber bundles distributed among the skeleton carbon fiber bundles, the content of the skeleton carbon fiber bundles accounts for 70-99 vol% of the total content of the carbon fibers, and the content of the filling carbon fiber bundles accounts for 1-30 vol% of the total content of the carbon fibers. By optimizing the k value, the length and the content of the skeleton carbon fiber bundle and the filling carbon fiber bundle, the fitness between the uniformity of the filling carbon fiber bundle and the skeleton carbon fiber bundle is improved, so that the strength and the impact toughness of the carbon-ceramic brake disc are stably improved.
本发明提供一种基体中含短切碳纤维的碳陶刹车盘，所述基体中含短切碳纤维的碳陶刹车盘包含碳纤维、碳化硅、单质硅和残余碳，所述碳纤维包括骨架碳纤维束和分布于骨架碳纤维束之间的填充碳纤维束，所述骨架碳纤维束的含量占碳纤维总含量的70‑99vol％，所述填充碳纤维束的含量占碳纤维总含量的1‑30vol％。本发明通过优化骨架碳纤维束和填充碳纤维束的k值、长度及含量，提高填充碳纤维束均匀和骨架碳纤维束之间的适配度，从而使碳陶刹车盘的强度和冲击韧性稳步提升。
