Method for producing brake band for brake disc, method for producing brake disc, brake disc and brake band for brake disc
A method for manufacturing a brake band (2) of a brake disc (1) of a disc brake, comprising the steps of: a) preparing a mould (10) having an inner cavity (11) comprising a first portion (11a) having a shape corresponding to the shape of the brake band (2) to be manufactured; b) providing a tape 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 a porous ceramic material comprising silicon carbide (SiC), the upper outer preform (201) and the lower outer preform (202) are made of a porous ceramic material comprising silicon carbide (SiC) and infiltrated with silicon (SiC + Si), in which carbon barrier layers (201a, 200a, 200b, 202a) made of carbon are interposed between the upper outer preform (201) and the central preform (200) and between the lower outer preform (202) and the central preform (200), the preform (200, 201, 202) has the shape of a brake band (2) to be manufactured; c) placing the strip preform (20) in a mould and at a first portion (11a) of the inner cavity (11); and d) injecting a liquid or semi-solid aluminum alloy into the entire inner cavity (11) of the mould (11) in order to infiltrate the central preform (200) of the strip preform (20) made of a porous ceramic material with said aluminum alloy in order to obtain, at a first portion (11a), an aluminum metal matrix composite reinforced by said central preform (200), the aluminum metal matrix composite defines a brake band (2) to be produced. The brake band and the brake disc are manufactured at least by adopting the method.
