A method of making laminate foam material is provided. The laminate foam material includes a layer of non-foam material sandwiched between two layers of foam material. The non-foam material is bonded to the foam material, such as with a bonding agent and/or by heating respective surfaces of the foam material until the surface softens or melts. When a heating process is utilized, the non-foam material is pressed against the softened or melted foam material. As the foam material begins to cool, the non-foam material becomes bonded to the foam material. The non-foam material is narrower than the foam material and is positioned relative to the foam material such that the edges of the non-foam material are concealed by the foam material. Foam products, such as foam mats, can be formed from the laminate foam material by cutting across the width of the foam material.

Described is a heating means for thermally connecting two objects each having a plastic material, wherein, in the connecting, a first inner object is surrounded at least partially by a second outer object, and the heating means is located between the first inner object and the second outer object. The heating means has a ribbon-type structure, in which a plurality of openings is formed. These openings are dimensioned such that molten-on plastic material of the first inner object and/or of the second outer object can intrude and can connect to molten-on plastic material of the respective other object. Alternatively or in combination, the openings are filled with a plastic material, which can connect to molten-on plastic material of the first inner object and/or of the second outer object. The ribbon-type structure has a ferromagnetic material, which is inductively heatable and which has a Curie temperature that is lower than 460 C. and/or that is adapted to the melting temperature of the first inner object and/or of the second outer object. There is further described a welded arrangement as well as a welding system having such a heating means as well as a method for thermally connecting two objects each having a plastic material.

Described is a heating means for thermally connecting two objects each having a plastic material, wherein, during the connecting, a first inner object is surrounded at least partially by a second outer object, and the heating means surrounds the first inner object at least partially along a complete circumferential course around the first inner object, and is located between the first inner object and the second outer object. The heating means has a ribbon-type structure. The ribbon-type structure has an auxiliary heating material, which is inductively heatable, wherein the auxiliary heating material is spatially distributed or arranged along the circumferential course such that an electrical conductivity is interrupted at at least one position along the complete circumferential course around the first inner object. Further described are an arrangement and a system each having such a heating means as well as a method for thermally connecting two plastic objects.

A composite material is formed by irradiating a bonding position on a surface of the composite material with a laser to cause a reinforcing base member of the composite material, that is impregnated with a resin and onto which a bonding agent is applied, to be exposed and fluffed.

A method of fastening a second object to a first object includes: providing the first object with an attachment surface; providing the second object; placing the second object relative to the first object, with a resin composition in between the attachment surface and the second object, wherein the resin composition has a resin having a first viscosity and being in a flowable state; pressing the first and second objects against each other and causing mechanical vibration to act on at least one of the objects until the resin composition experiences a vibration induced activation, which includes at least one of reduction of the viscosity of the resin compared to the first viscosity and activation of particles dispersed in the resin. The pressing and mechanical vibration are continued or repeated until the resin has at least partially cross-linked and the viscosity of the resin is increased compared to the first viscosity.

An implantable medical device includes a first component including a first material, a second component including a second material, and a fiber matrix including a plurality of fibers. The fiber matrix joins the first component to the second component. The fiber matrix includes a first a first portion connected to the first component, and a second portion connected to the second component. The first portion of the fiber matrix is interpenetrated with, and mechanically fixed to, the first material. The first portion of the fiber matrix directly contacts the first material.

A sandwich panel includes a reinforcement member having a recess formed to extend in a longitudinal direction over a predetermined length and open laterally. The thermoplastic resin core material has a rectangular flat board-like shape, and includes a protrusion which is disposed on a peripheral side surface portion thereof and which is capable of being laterally press-fit with respect to the recess. The protrusion has opposing surfaces respectively opposing mutually opposed inner surfaces of the recess, the opposing surfaces being oriented so as to protrude from the peripheral side surface portion. At least one of the opposing surfaces is provided with a plurality of protuberances disposed at an interval in the longitudinal direction. Each of the protuberances has a predetermined height from the opposing surfaces enabling the protuberances to tightly contact the inner surfaces of the recess at the time of press-fitting.

A connection system has a first adhesion segment, on which a first connection region is formed, a second adhesion segment, on which a second connection region is formed, and a solidifiable liquid connection substance for connecting the two adhesion segments in a material fit, wherein at least one of the two connection regions is formed flexibly, such that, when the liquid connection substance is introduced between the two connection regions which are opposite one another in an assembly arrangement of the two adhesion segments, a material connection is formed between the two connection regions automatically as a result of the elastocapillary effect via the liquid connection substance.

An automobile interior trim has a resin core material and a skin material that is joined on a surface of the resin core material. The automobile interior trim has stitches that are formed on the skin material by sewing the skin material with threads. The skin material and the stitches are cut by a laser beam to generate a cut section. The vicinity of the cut section has a structure in which threads of the stitches and the raw material of the skin material are melted by heat of the laser beam, mixed together, and solidified.

A method of fastening a second object to a fiber composite part including a structure of fibers embedded in a matrix material includes: providing the fiber composite part including an attachment surface, with a portion of the structure of fibers being exposed at the attachment surface; providing the second object; placing the second object relative to the fiber composite part, with a resin in a flowable state between the attachment surface and the connector; pressing the second object and the fiber composite part against each other and causing mechanical vibration to act on the second object or the fiber composite part or both, thereby causing the resin to infiltrate the exposed structure of fibers and activating the resin to cross-link; whereby the resin, after cross-linking, secures the second object to the fiber composite part.
