Abstract:
A thermoplastic welding apparatus includes a thermoplastic welding tool, at least one tooling surface in the thermoplastic welding tool, a magnetic induction coil in the thermoplastic welding tool and generally encircling the at least one tooling surface and at least one smart susceptor in the thermoplastic welding tool at the at least one tooling surface. The magnetic induction coil is adapted to generate a magnetic flux field oriented generally parallel to a plane of the at least one smart susceptor.
Abstract:
A process for reinforcing a trim panel for a vehicle using one or more micro-truss reinforcement patches. Each micro-truss reinforcement patch is secured to an inner surface of a show surface panel of the trim panel while it is in a partially cured state and then fully cured. The micro-truss patch is fusion bonded to the panel.
Abstract:
A kit for fusing piping includes a plurality of couplings, each coupling having a susceptor layer concentric with a weld zone. A control unit provides a current to a wand with a handle for gripping by a user. The handle has opposing jaws mounted on the distal end, each jaw including an arcuate conductor such that the arcuate conductors form a circular inner diameter when the jaws make contact. A lever system couples to the distal end for opening and closing the jaws. The lever system includes a spring for selectively biasing the lever system in a latched position with jaws closed and an open position with the jaws open. Each coupling is sized such that the jaws will only close about the weld zone. The arcuate conductors create a fuse zone about the susceptor layer and the spring is outside the fuse zone.
Abstract:
A process for laminating a material layer to a support including: providing the support, applying the material layer to the support, a heat-activatable adhesive being applied to s side of the material layer facing the dimensionally stable support and/or to the side of the dimensionally stable support facing the material layer, pressing the flexible material layer and the dimensionally stable support together by means of a lower dimensionally stable mold half and an upper dimensionally stable mold half, irradiating the mold halves, the support and the material layer with electromagnetic radiation, in particular with microwave radiation, high-frequency radiation or induction radiation, whereby the adhesive is activated directly or indirectly.
Abstract:
The invention relates to the construction of a sealed connection between an elastomeric or synthetic polymer flexible pipe or hose and a metallic coupling member (13′). The coupling member surrounds an armour layer (9′) at a free end of the flexible pipe or hose. A sealing area (3′) is defined by a recessed portion of the pipe coupling (13′) into which a sealing material (23) is introduced. An inner liner layer (1′) of the flexible pipe or hose may extend into the sealing area (3′) where it is bonded to the sealing material. The sealing material (23) and the inner liner layer (1′) may each be comprised of a semi-crystalline thermoplastic material. Furthermore, a reinforcement material (2′) be provided in the inner liner layer (1′).
Abstract:
The invention includes a composite material comprising magnetic field responsive particles distributed in a reversibly crosslinked polymer, wherein the reversibly crosslinked polymer includes thermally reversible bonds. In one embodiment, exposing the composite material to an electromagnetic field allows for crack-healing, remolding and/or bonding of the material.
Abstract:
A flexible ferromagnetic strip is used to induction-weld seams in polymer pipes. The strip is a blend of strontium ferrite, a surfactant, and an LDPE binder. A process to produce the profile is to mix the ingredients together followed by granulation and extrusion or calendering. The strip is used in conjunction with an induction coil sized to fit over a polymer pipe coupling containing the strip and separate segments of polymer pipe. The strip is heated by induction current induced by an electromagnetic field generated by the coil. The heated strip causes the polymer pipe segments to be thermoplastically welded together.
Abstract:
A method for production of a joining component, the method comprising the steps of providing a metal section which is inductively heatable and defines an axial through aperture; and coating the metal element with a thermoplastic material by a single-component injection-moulding of a base body of the joining component around the metal section so that the base body includes: a holding section formed as a cylindrical shaft and a flange, the flange including a first and second sides, and an inner side of the metal section is joined to the flange and an exposed outer side of the metal section faces away from the flange; and a the second side of the flange is axially recessed within the aperture; and a joining surface is comprised of the outer side of the metal section and a portion of the second side of the flange radially outward of the metal section.
Abstract:
A joining component, for axial joining to a workpiece, comprises a base body composed of thermoplastic material and including a holding section and a flange section, with a joining surface including both a portion of the flange section and a metal section which can be heated inductively. The metal section is in this case integrated in the flange section.
