The invention relates to a method for producing a sandwich composite material (9, 9'), comprising at least two outer metal cover layers (4a, 5a, 4a', 5a', 9a, 9b) and at least one plastic layer (4b, 5b, 4c', 5c', 9c) arranged between the cover layers, wherein: at least two metal semi-finished products (4a, 5a, 4a', 5a') coated with plastic (4b, 5b, 4c', 5c') on one side are provided; in order to establish a connection between the plastic layers of the semi-finished products, at least one of the sides of the metal semi-finished products coated with the plastic is activated before the connecting occurs; and the semi-finished products are connected to each other by means of the sides of the semi-finished products coated with plastic in order to form a sandwich composite material. The problem of providing a method that ensures an improvement in the process reliability in the production of sandwich composite materials from semi-finished products coated with at least one plastic layer on one side is solved by activating the plastic layer of the semi-finished products directly from the side of the semi-finished product coated with plastic.

A container-forming process is used to form an insulative container. The container-forming process includes a staging-materials operation, a body-forming operation, and a brim-forming operation.
摘要:
Two components (32, 34), that may be thermoplastic composite components, are joined together by a thermoplastic film (36) forming a thermoplastic joint (31) between the components (32, 34). The thermoplastic film (36) is preferably amorphous and it preferably fuses during the formation of the join (31).

In accordance with embodiments of the invention, a reinforcement and/or lining method is provided, wherein a thermoplastic reinforcement and/or lining element is subject to mechanical energy impact and mechanical pressure by a tool so that reinforcement and/or lining material of the reinforcement and/or lining element is liquefied and pressed into porous material to reinforce the porous material. In embodiments, in at least one axial depth, the reinforcement and/or lining element is segmented as a function of the circumferential angle so that at this axial depth the circumferential wall of the initial opening in first regions is in contact with the reinforcement and/or lining element and in second regions is not in contact with the reinforcement and/or lining element.

The present invention relates to a process for manufacturing a hollow body comprising a thermoplastic wall and a fibrous reinforcement welded on at least one portion of the outer surface of said wall, the fibrous reinforcement comprising a thermoplastic similar to or compatible with that of the wall of the hollow body, having a thickness of at least 1 mm and comprising from 30 to 60% in weight of fibres, according to which: . the portion of the outer surface of the hollow body, where the reinforcement will be welded, is heated; . the fibrous reinforcement is also heated so as to soften or even preferably melt the thermoplastic of the reinforcement; and . the reinforcement is moved to and applied to said portion of the outer surface of the hollow body, wherein the step of applying the reinforcement to said portion of the outer surface of the hollow body comprises: . applying an initial pressure on at least one portion of the reinforcement; . applying pressure for the final welding using robotized pressure applying means.
摘要:
Methods of producing fully formed labeled polymeric articles are described. The labeled articles are formed by expanding labeled preforms, such as by blow molding. Also described are preforms, label assemblies, adhesives, ink compositions, and various optional aspects, all of which are particularly well suited in conjunction with the methods described herein.
摘要:
A method for joining two components includes positioning a thermoplastic polymer portion of a first component adjacent a thermoplastic polymer portion of a second component such that the first and second portions form an interface. At least one of the portions includes a microstructure having a plurality of closed cells, each cell containing a void and each cell having a maximum dimension extending across the void. The method also includes exerting pressure on the thermoplastic polymer portions to form a bond at the interface that holds the portions together. The plurality of closed cells, and especially those adjacent the surface of the thermoplastic polymer portion that form the interface, help isolate thermally and/or chemically the surface from the remainder of the portion.
