  • Publication number: 20200147948
    Abstract: A joint between at least one element of metal material and at least one element of plastic material is obtained by pressing these elements in contact against each other, with a simultaneous application of heat. A cladding of metal material and/or of plastic material is applied above the joint by additive manufacturing technology.

  • Patent number: 10589469
    Abstract: A welded joint between at least one metal material element and at least one thermoplastic material element is obtained by pressing the elements against each other while applying heat. Contact surfaces of the metal material, which are in contact with the thermoplastic material, are provided with uneven surface portions having a distribution of asperities. With heat applied, the thermoplastic material fills spaces between these asperities and maintains this configuration after subsequent cooling, thereby improving strength of the joint. The uneven surface portions are obtained in a preliminary forming step of the metal material in a press mold, which is configured with a forming surface for generating the uneven surface portions by mechanical deformation and/or with a device for guiding a laser or electron beam. By this technique, hybrid components are obtained made of one or more elements of metal material between which a shaped component of thermoplastic material is interposed.

  • Publication number: 20190184462
    Abstract: A structural joint between two components of metal material is obtained by carrying out an electrical resistance welding spot between said components and subsequently performing a step of applying a cladding of metal material by an additive manufacturing technology. In one example, after a first step of applying a coarse base cladding, a second step of applying a fine cladding is carried out, again by additive manufacturing technology. The fine cladding can include a distribution of stiffening micro-ribs above the base cladding. The same method can also be applied to a single sheet metal component, rather than to a welded joint.

  • Patent number: 9376538
    Abstract: A nanoporous polymeric membrane is obtained by bombing a polymer film by means of high energy focused heavy ion beams and subsequently performing chemical etching to remove the portions of the polymer film in the zones degraded by the ion bombing, in such a manner to obtain pores passing through the polymer film. The heavy ion bombing is performed after interposing between the source of ions and the polymer film, adjacent to the film, an amplitude mask having an ordered arrangement of nanopores and having sufficient thickness to prevent the passage of the heavy ions that are not directed through the pores of said amplitude mask, in such a manner to obtain in the polymer fill an ordered arrangement of nanopores having an aspect-ratio at least exceeding 10 and preferably exceeding 100.

  • Patent number: 8975319
    Abstract: Described herein is a method for producing a nanocomposite material, including nanofillers dispersed in a polymeric matrix. The method comprises the steps of: a) providing a starting thermoplastic polymeric material, having a crystalline structure; b) providing one or more precursors of the nanofillers; c) bringing the starting thermoplastic polymeric material into the molten state and dispersing the precursor or precursors therein; d) subjecting the precursor or precursors to in situ thermolysis, thereby generating the nanofillers directly within the melted material; and e) causing solidification of the molten polymeric material including the nanofillers, thereby obtaining the nanocomposite material. The precursor or the precursors are selected from among carbonates and acetylacetonates and the thermoplastic polymeric material is isotactic polypropylene.
