Abstract: Method and plant for manufacturing braking elements such as vehicle brake pads. The plant can comprise a first station that applies an adhesive to a first face of a metallic element; a second station that applies to the first face of the metallic element a block of friction material; a checking station that verifies the presence of the adhesive by detecting the gray level of a plurality of points of at least one zone of the first face; and a processing unit that compares the gray level detected for each point with a first threshold value, counts the number of points that have a gray level that satisfies a relationship (which is a function of the threshold value,) and compares such a value with a second threshold value to discard those metallic elements for which the percentage calculated does not correspond to the second threshold value.

Abstract: An asbestos-free organic friction material, in particular for producing brake pads and shoes for vehicles made up of a composition or mixture having a fibrous base, a filler, an organic binder and optional metal oxides. The composition is completely free of copper and copper compounds or alloys and includes in the fibrous base, together with inorganic and/or organic fibers, from 1% to 10% by volume, calculated relative to the total volume of the composition, of stainless steel fibers. The friction material further includes between 1% and 25% by volume of a system of fibrous oxides consisting of potassium hexatitanate and zirconia.

Abstract: A geopolymeric ink formulation for direct 3D printing containing a geopolymeric formulation whose components are present in such proportions as to be subjected to a geopolymerization reaction and to provide, at the end of the reaction, a solid geopolymer and wherein the formulation, before and during at least a part of the geopolymerization reaction, wherein three-dimensional chemical bonds have not yet been formed, forms a reversible-gel, non-Newtonian, viscoelastic fluid. The formulation is extruded through a 3D printing tool equipped with nozzle into strands according to a geometry such as to create a three-dimensional structure on one or more layers. The extrusion preferably takes place within a hydrophobic liquid, such as oil.

Abstract: A tunnel oven and associated method for the heat treatment of friction elements, and in particular of braking elements such as brake pads is provided. The friction elements are arranged on a resting surface of a conveyor device, are moved between an inlet opening and an outlet opening of the tunnel oven, and are heated by irradiation by at least one heating device. The heating device includes a radiating plate made from stainless steel arranged facing the conveyor device and heated by electromagnetic induction by means of at least one inductor arranged facing the radiating plate and spaced apart therefrom on the side opposite to the conveyor device. A cooling air flow for the braking elements between the resting surface and the radiating plate is directed in counterflow to a feeding direction of the conveyor device.

Abstract: A method in which at least one piezoceramic sensor, which converts every mechanical force to which it is subjected into an electrical signal and having a Curie temperature higher than 200° C., is solidarized directly onto the surface of a metal support element of a vehicle braking element, which during use faces a vehicle element to be braked. While in contact with such a surface, an electrical circuit is implemented that picks up and eventually processes the electrical signal, the electrical circuit being connected with a connector integrated with the metal support element. An electrically insulating layer sandwiches the at least one piezoceramic sensor and the electrical circuit, and a block of friction material with an underlying damping layer is formed upon the electrically insulating layer. After forming the block of friction material, the piezoceramic sensor is polarized by applying a predetermined potential difference thereto by means of the connector.
