Ultra-thick carbon-based brake pad and manufacturing method thereof

The invention discloses an ultra-thick carbon-based brake pad which comprises a plurality of carbon-carbon bonding layers which are sequentially wound from inside to outside, every two adjacent carbon-carbon bonding layers are connected into a whole through needling, and a winding wire is arranged between every two adjacent carbon-carbon bonding layers. Wherein the winding wire comprises a first-direction winding wire, a second-direction winding wire and a hoop wire, an included angle alpha is formed between the first-direction winding wire and the second-direction winding wire, and the included angle alpha is larger than 0 degree and smaller than 90 degrees; or, the winding wire comprises a one-way winding wire. In the needling process, the carbon felt layer deforms. When the thickness of the carbon-based brake pad is larger than 60 mm, deformation of the carbon felt layer can cause interlayer local upheaval of the super-thick carbon-based brake pad, virtual thorns are generated, and then the super-thick car
