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 brake element is sensorized by at least one piezoceramic sensor arranged between a metallic support element and a block of friction material of a brake element, the sensor being completely embedded within the block. An electrical voltage signal generated by at least one piezoceramic sensor, without the need for a power supply, is picked up by an electrical circuit integrated into the metallic support element. The electrical voltage signal is processed in the form of equal length of samples per unit of time of the detected signal by successively processing in real time each sample of equal length of time sample of the signal by applying an algorithm. The algorithm is selected from at least one of a sequence of integrations of voltage values in the sample carried out in an interval of time in the order of milliseconds; FFT voltage data sample; and integral of the voltage data sample.

Abstract: Methods and devices for estimating a residual torque between the braked (e.g., brake disk or drum) and braking elements (e.g., support plate or friction block) of a vehicle based on acquired and reference temperatures, where the reference temperature can be calculated using an N-dimensional calculation model with an N-dimensional vector of input variables, and where said N-dimensional calculation model can be an analytical or experimental characterization of the thermal behavior of the brake.

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: A tunnel oven and associated method for the heat treatment of friction elements, and in particular 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 using 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.
