A porous body belt includes a body to be connected including a porous body, a connecting material A that is disposed on the body to be connected by spanning a gap between end portions of the body to be connected and contains a fiber A and a resin material A, and the resin material A penetrates at least a part of a void portion of the porous body of the body to be connected, and bonds the end portions of the body to be connected to each other.

A non-woven textile may be formed from a plurality of thermoplastic polymer filaments. The non-woven textile may have a first region and a second region, with the filaments of the first region being fused to a greater degree than the filaments of the second region. A variety of products, including apparel (e.g., shirts, pants, footwear), may incorporate the non-woven textile. In some of these products, the non-woven textile may be joined with another textile element to form a seam. More particularly, an edge area of the non-woven textile may be heatbonded with an edge area of the other textile element at the seam. In other products, the non-woven textile may be joined with another component, whether a textile or a non-textile.

A metal-resin joined body having a high joining strength is obtained. The metal-resin joined body of the invention is a metal-resin joined body 10 including a metal member 30 made of a metal and a resin member 20 made of a thermoplastic resin, in which a resin joint surface 22 of the resin member 20 is joined to a metal joint surface 32 of the metal member 30. The metal member 30 includes an anchor portion 34 protruding from the metal joint surface 32. The anchor portion 34 includes an aggregate 38 of a plurality of metal particles 36, and a plurality of voids 40 formed between the plurality of metal particles 36. The plurality of voids 40 are connected inside the anchor portion 34 and are connected from a surface of the anchor portion 34 to the inside of the anchor portion 34.

A method for joining two objects by anchoring an insert portion provided on one of the objects in an opening provided on the other one of the objects. The anchorage is achieved by liquefaction of a thermoplastic material and interpenetration of the liquefied material and a penetrable material, the two materials being arranged on opposite surfaces of the insert portion and the wall of the opening. Before such liquefaction and interpenetration, an interference fit is established in which such opposite surfaces are pressed against each other, and, for the anchoring, mechanical vibration energy and possibly a shearing force are applied, wherein the shearing force puts a shear stress on the interference fit.

In some of these products, the non-woven textile may be joined with another textile element to form a seam. More particularly, an edge area of the non-woven textile may be heatbonded with an edge area of the other textile element at the seam. In other products, the non-woven textile may be joined with another component, whether a textile or a non-textile.

Various embodiments relate to plastic-metal junctions and methods of making the same via laser-assisted joining. The present invention provides a method of forming a junction between a metal form and a solid plastic. The method can include laser treating a surface of a metal form to generate a feature (e.g., a plurality of at least one of pores and grooves) in the surface of the metal, wherein the laser has an angle of incidence with the surface of the metal of other than 0 degrees. The method can include contacting the metal surface including the feature with a flowable resin composition. The method can include curing the flowable resin composition to form the solid plastic, to provide the junction between the metal form and the solid plastic.

A method of fastening an edge structure to a construction element includes providing the construction element, being a planar structure with with two cover regions and a middle region between the cover regions; providing the edge structure being continuously extended, the edge structure having contact surfaces with a thermoplastic material shaped to lie against the cover regions in an outer surface of the construction element, and, opposite the contact surfaces, a coupling-in surface for coupling energy into the edge structure; coupling energy into the edge structure and pressing the contact surfaces against the cover regions until at least a portion of the thermoplastic material is liquefied and pressed into the cover regions; and repeating or continuing the steps of coupling and pressing until the edge structure is attached to the building element at a plurality of discrete locations or over an extended region along an edge of the construction element.

A method for joining a device to an object with the aid of a combination of ultrasonic vibration energy and induction heating, wherein the device includes a portion of a thermoplastic polymer and a susceptor additive wherein this portion is at least partly liquefied or plasticized through the ultrasonic vibration energy in combination with the induction heating and wherein the joining includes establishing a connection between the device and the object which connection is at least one of a positive fit connection, a weld, a press fit connection, and an adhesive connection. The induction heating is applied for rendering the device portion suitable for absorption of ultrasonic vibration energy than other device portions by raising its temperature above the glass transition temperature of the polymer. The ultrasonic vibration energy is used for liquefying or at least plasticizing the thermoplastic polymer of the named device portion.

The invention relates to a molded product made of fiber material with a connection element (11). In order to achieve a particularly firm anchoring of the connection element (11) in the fiber material of the molded product, the connection element (11) has a connecting wall (17) with holes (18) through which the fiber material of the molded product projects.
