摘要:
A method of forming three-dimensional composite comprising steps of: (a) manufacturing at least one shaping member; (b) fitting each of the at least one shaping member on each of at least one mold; (c) adhering at least one connection sheet on said each shaping member so as to form each of at least one semi-finished product; (d) fixing said each semi-finished product in a cavity; and (e) heating said each semi-finished product and vacuuming the cavity. Said shaping member has at least one orifice and covers said each mold, and each connection sheet has a substrate and an adhesive layer, a melting point of the adhesive layer is less than the substrate. Said each semi-finished product in the cavity is heated until the adhesive layer melts, and the cavity is vacuumed so that the adhesive layer penetrates into said each shaping member, thus producing a three-dimensional finished product.

A method for locating a material having thermoplastic properties in pores of bone tissue includes providing a pin having the material having thermoplastic properties and a core, wherein the material having thermoplastic properties is arranged on the circumferential surface of the core constituting an outer region of the pin. An opening is provided in the bone tissue, and the pin is positioned at least partly in the opening. The outer region of the pin is then impinged with mechanical vibration energy for a time sufficient for liquefying at least part of the material having thermoplastic properties, and, in a liquefied state, pressing it into the pores of the bone tissue surrounding the opening. The vibration energy is stopped for a time sufficient for re-solidification of the liquefied material, and then the core is removed.

A method of manufacturing a heterogeneous composite includes the steps of providing a first constituent and a second constituent, wherein the first constituent is porous or capable of developing pores when under hydrostatic pressure, and the second constituent comprises a solid having thermoplastic properties; positioning the second constituent relative to the first constituent and coupling energy into the second constituent to cause at least portions of the second constituent to liquefy and to penetrate into pores or other structures of the first constituent, whereby the first constituent is interpenetrated by the second constituent to yield a composite; and, causing an irreversible transition at least of the second constituent to yield a modified composite.

A second object, which includes a thermoplastic material, is bonded to a first object, which includes a first object material having an at least partially cross-linked polymer not miscible with the thermoplastic material. The method includes the steps of pressing the second object against the first object and coupling energy into the second object until the thermoplastic material is at least partially liquefied and the first object material in a vicinity of an interface to the thermoplastic material is above its glass transition temperature, and until the thermoplastic material is caused to penetrate into at least one of cracks, pores and deformations of the first object material, and letting the thermoplastic material re-solidify.

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 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.

A connector and a method of anchoring the connector to a first object that includes providing the connector having a sleeve element and a piston element with a shaft portion, providing a through hole in the first object, and inserting the connector through the through hole and until a distal portion of one of the sleeve and/or the piston element rests against the second object. Mechanical oscillations are coupled into the piston element while the piston element is pressed towards the distal side, and thereby liquefying portions a thermoplastic material at an interface portion between the sleeve element and the piston element while a periphery of the interface portion is adjacent the circumferential wall, and causing the liquefied thermoplastic material to flow radially outward from the periphery and into structures of the first object and/or along an inner surface.
摘要:
A method of anchoring a joining element to a hollow core board with the aid of mechanical vibration. The hollow core board has a first and second outer layers and a middle layer disposed between the outer layers. An opening, including a mouth, is provided in the hollow core board, the opening penetrating the first outer layer and the middle layer. The joining element includes a wall anchoring portion situated between a proximal end and a distal end thereof. A distal end of the wall anchoring portion is positioned into or onto the mouth with a sealing portion on a proximal end of the wall anchoring portion. The wall anchoring portion is forced through the mouth by applying mechanical vibration and a force parallel to the joining element axis, whereby thermoplastic material of the wall anchoring portion is liquefied and pressed into the first outer layer.

The invention relates to a device (1) for the amelioration of a recess (8), e.g. a recess in a (human) bone (7). The device comprises an element (2) for producing or coupling mechanical energy, and a cylindrical collar (4) comprising a cylindrical lateral surface having an outside diameter and having a central recess (26) for accommodating a guide pin (3). The guide pin (3) is provided to be inserted substantially down to the base of the recess (8) before applying oscillations, and in the region of the end thereof facing the base of the recess it is surrounded by an amelioration sleeve (6) made from a material that can be liquefied by way of ultrasonic oscillations. The cylindrical lateral surface of the amelioration sleeve (6) substantially has the same outside diameter as the collar (4), and the guide pin (3) is accommodated in the central recess (26) in a displaceable manner such that the collar (4) upon applying ultrasonic oscillations can be displaced relative to the guide pin (3) in the direction toward the base of the recess (8) while liquefying and laterally and/or longitudinally displacing the material of the amelioration sleeve (6).

The invention relates to an edge trim for pieces of furniture, comprising a meltable layer. In order to improve a generic edge trim such that the same is more versatile and can especially be mounted on a wider selection of surfaces, the molecular structure of the meltable layer contains both polar and non-polar parts.
摘要:
A three-dimensional molded body, a method for producing a three-dimensional molded body and a method for producing an adhesive bond between a polymer-containing material and a molded body having an inorganic porous framework structure in at least partial areas are described. In all cases the porous structure of the molded body comprising inorganic material is brought in contact with a polymer-containing material which is heated until the heated material enters into a joint connection with the molded body based on adhesive interactions, interfacial interactions, electrostatic interactions or any combination thereof, in which the pore-like voids of the porous structure are filled completely with the polymer-containing material, which stabilizes the molded body so that it has dimensional stability after cooling.
