The present invention relates to a timepiece component () made up of a polymer-based matrix () and a reinforcement () that consists of at least two different kinds of cut fibres (), one of which is a polyazole.

Timepiece component made of forged composite

A case element for a timepiece is described, having a through-hole and bearing a pushbutton including a tube, that is accommodated inside the through-hole and is closed by an actuating surface at its end oriented towards the outside, the actuating surface being intended to be pressed by a user in order to actuate a timepiece mechanism arranged inside the case element, wherein the pushbutton is made in one piece, of a bulk metallic glass, and further includes a connection surface which is arranged against the case element so as to establish a permanent, water-resistant connection with the latter, and wherein the actuating surface is able to move, with respect to the connection surface, in response to a pressure exerted thereon by the user. A corresponding production method is also described.

Case element for a timepiece comprising a pushbutton made of bulk metallic glass

Preform and manufacturing process producing heterogeneous components with a first fraction () made from a first metallic material and having a cellular structure with stochastic or regular cells, and a second fraction () made from a second metallic material different from the first metallic material, in which the second fraction () at least partly infiltrates the cells of the first fraction (). The second fraction is poured into the preform which also acts as a mould. The finished product after machining may have a unified surface of the second fraction or several zones exposing the second fraction, the first fraction, the cellular structure which is open or infiltrated with the second metallic fraction, or open zones, in a predetermined design.

Composite material, heterogeneous component and manufacturing process

The present invention relates to a manufacturing process for a watch component () in composite material with a ceramic matrix comprising the following steps: depositing in a mould a succession of layers () each comprising a ceramic powder (), at least one layer () further including fibres () mixed with the ceramic powder (), the fibres () being arranged randomly; performing a FAST/SPS sintering operation; demoulding the sintered watch component comprising the succession of layers (), and optionally machining the sintered component to the final dimensions of the watch component (). The fibres () are visible on the surface of the watch component ().

Manufacturing process for a watch component made of a composite material

A laminated structure for an E-document, comprising a first support layer defining at least two flat flaps connected by at least one fold line, the first flap supporting an antenna and a microcircuit device enabling contactless data exchange, the second flap supporting an electromagnetic interference element arranged in relation to the microcircuit device so as to be able to oppose contactless reading and/or writing of the microcircuit device in at least one folded configuration of the structure, the structure having at least one heat-activated or pressure-sensitive adhesive layer making it possible to receive the microcircuit device and/or the antenna and/or the electromagnetic interference element at least in part in its thickness, and/or the flaps having at least one layer of an adhesive and/or a fibrous layer and/or a polymer layer having a different thickness for each of the flaps.
