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 layer (200) made of porous ceramic material comprising silicon carbide (SiC), an upper outer layer (201) and a lower outer layer (202), said upper outer layer (201) and said lower outer layer (202) being made of porous ceramic material comprising silicon carbide (SiC) and infiltrated with silicon (SiC+Si), said upper outer layer (201) and said bottom outer layer (202) being arranged in an opposing way and on opposite sides of the central layer (200); 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) so as to infiltrate only the central layer (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 at least with the aforesaid method.
