A joining method for joining a first member having a hole that is opened on at least one surface, to a second member including a material of which a melting temperature is lower than that of a constituent material of the first member, includes: laminating the second member on the first member so as to cover an opening of the hole; and introducing that material of the second member which is softened or melted into the hole through the opening and curing the material of the second member.

Embodiments herein include compositions, extruded articles, and methods of making the same. In an embodiment, an extruded article is included. The extruded article can include an extruded segment comprising a first composition. The first composition can include a polymer resin, particles and fibers. The fibers can be disposed within the first composition exhibiting a substantially non-aligned directional orientation. In an embodiment, an extruded article is included having a first portion comprising a first composition having a first fiber orientation and a second portion comprising a second composition having a second fiber orientation. The first composition can include a polymer resin and fibers. The second composition can include a polymer resin, particles and fibers. The fibers of the second composition can be oriented more randomly than the fibers of the first composition. Other embodiments are also included herein.

Method and device for connecting two webs (1), reinforced with unidirectionally oriented continuous fibres, by ultrasonic welding, wherein the fibres are embedded in a matrix of polycarbonate and the webs have abutting edges that are substantially square and substantially flat, characterized by the following steps:arranging the webs abutting one another in the region of the abutting edges in a welding device between a sonotrode (2) and an anvil (3),welding the webs by means of ultrasound, wherein the sonotrode and the anvil exert pressure on the webs to be welded in the melting region between the webs and perpendicularly to the abutting edges of the webs,removing the welded-together webs (4) from the welding device.

A thermoformed article is disclosed that includes a self-supporting structural base layer, a covering applied to a first side of the base layer, and one or more secondary features co-injected upon a second side of the base layer. The covering and the secondary features of the thermoformed article are applied to the base layer during the same molding operation. Also disclosed is a process for forming a thermoformed article that includes placing a covering in a mold tool as a first layer, placing a self-supporting structural base layer in the mold tooling as a second layer, closing the mold tooling with the covering and base layer, and co-injecting upon a side of the base layer opposite to the covering one or more secondary features.

Method of manufacturing a tire tread having a plurality of raised elements, each having a contact face intended to come into contact with a ground when the tire is rolling and lateral faces connected to this contact face. The method of manufacture comprises: preparing a green form of the tire; laying a cover layer over all or part of an external surface of the green tire; laying the green tire in a mold; with the mold comprising a blade, using this blade to mold a lateral face of a raised element; vulcanizing the green tire to obtain the tire cutting the cover layer using cutting means belonging to the mold; during the molding of the lateral face driving with the blade a cut part of the cover layer into the green tire so that the lateral face of the raised element is partially or fully covered.

The method (10) of molding a composite component comprises: a step (105) of positioning a layer of geotextile on a mold so that a lower surface of the layer of geotextile is positioned against the mold, a first step (110) of coating an upper surface of the layer of geotextile positioned during the positioning step with a biodegradable resin, a step (115) of bonding a layer of fibers, having a higher rigidity than the layer of geotextile, against the coated layer of geotextile, and a second step (120) of coating an upper surface of the layer of fibers with a biodegradable resin.

A vehicle seat frame includes a back panel and a load carrier component attached to the back panel. The back panel includes a first polymeric matrix and a first plurality of fibers disposed therein. The load carrier component includes a second polymer matrix and a second plurality of fibers disposed therein.

A method of assembling a first part made from a metal and a second part includes providing a first part comprising an assembly surface, and a second part comprising at least one through orifice. At least part of the second part is arranged on the assembly surface such that the orifice extends across from the assembly surface. A metal connecting part is positioned on the orifice to cover the orifice across from the assembly surface. The connecting part and/or the assembly surface are projected on one another to obtain high-speed plating and welding between the connecting part and the surface part.
