Carbon fiber brake disc preforms serve as the precursor for manufacturing carbon-ceramic brake discs. They are produced by needling long-fiber carbon fiber and web into non-woven composite fabric, which is then cross-layered at different angles. Needles with reverse hooks introduce fiber bundles in the thickness direction (Z-direction), forming a quasi-three-dimensional structure with specific strength and porosity.

Needles with reverse hooks introduce fiber bundles in the thickness direction (Z-direction), forming a quasi-three-dimensional structure with specific strength and porosity. This structure provides skeletal support for subsequent processes such as chemical vapor deposition (CVI) and liquid silicon infiltration (LSI), playing a decisive role in the basic structure and performance of carbon-ceramic brake discs.
