METHOD FOR MAKING A BRAKING BAND OF A BRAKE DISC, METHOD FOR MAKING THE BRAKE DISC, BRAKE DISC, AND BRAKING BAND FOR BRAKE DISC
A method for making a braking band (2) for a brake disc (1) for a disc brake, comprising the following steps: a) preparing a mold (10) having an inner cavity (11), which comprises a first portion (11a) of a shape corresponding to the braking band (2) to be made; b) preparing a band preform (20) comprising a central preform (200), an upper outer preform (201) and a lower outer preform (202), said central preform (200) being made of porous ceramic material comprising silicon carbide (SiC), said upper outer preform (201) and lower outer preform (202) being made of porous ceramic material comprising silicon carbide (SiC) and infiltrated with silicon (SiC+Si), wherein a carbon barrier layer (201a, 200a, 200b, 202a) made of carbon is interposed between the upper outer preform (201) and the central preform (200) and between the lower outer preform (202) and the central preform (200), said preforms (200, 201, 202) having the shape of the braking band (2) to be made; c) placing said band preform (20) inside the mold at the first portion (11a) of said inner cavity (11); and d) injecting a liquid or semi-solid aluminum alloy inside the entire inner cavity (11) of the mold (11) to infiltrate the central preform (200) of said band preform (20) made of porous ceramic material with said aluminum alloy, obtaining at the first portion (11a) an aluminum metal matrix composite reinforced by said central preform (200) which defines the braking band (2) to be made. A braking band and a brake disc are made with at least the aforesaid method.
