A fiber-reinforced thermoplastic resin member welding method includes: heating, by a heating unit, a welding target portion in which plural fiber-reinforced thermoplastic resin members layered on top of each other, each of the plural fiber-reinforced thermoplastic resin members including thermoplastic resin as a main composition, and the thermoplastic resin including reinforcing fibers; applying pressure, by a pressure applying unit, to the welding target portion; and cooling, by a cooling unit, at least a surface of the welding target portion at the same time as when the welding target portion is being heated by the heating unit or after the welding target portion has been heated by the heating unit.

A grooved roller having a multiplicity of guide grooves running parallel to one another and in encircling fashion over the circumference of said grooved roller and serve for guiding strength members of flattened cross section before they enter a roller calender, which strength members have, in cross section, a first diameter and, perpendicular thereto, a second diameter, the second diameter is smaller than the first diameter, and the two diameters are each determined at the points with the greatest widths. The guide grooves each have a U-shaped cross section with a groove base extending parallel to the roller axis and with two groove walls extending perpendicularly to the roller axis. The groove base has a width which at least corresponds to, and is up to 5% greater than, the first diameter of the strength member, and the groove walls have a height which is 50% to 90% of the second diameter of the strength member.

A pneumatic tire includes: a tire frame member having a tire inner surface made of a resin material; and a sound absorbing body that is made of a thermoplastic resin material, that is configured to absorb sound, and that is coupled to the tire inner surface via a welded portion.

The pipe includes at least one tubular sheath delimiting a passage for circulation of the abrasive material, at least one tensile armor layer externally positioned with respect to the tubular sheath, the armor layer including a plurality of filiform armor elements. It further includes a protective internal layer positioned inside the tubular sheath in the circulation passage, the protective internal layer including an elastomeric matrix and a longitudinal reinforcement assembly embedded in the matrix.

A filament suitable for use with a fused filament fabrication process includes an elongated body. The elongated body defines and extends along a central longitudinal axis of the elongated body. The filament includes at least one continuous reinforcing strand, which is encapsulated within the elongated body. The continuous reinforcing strand extends uninterrupted between a first end and a second end of the elongated body, along the central longitudinal axis. The elongated body includes a ferromagnetic sensitive element that is capable of inductively heating the elongated body. The ferromagnetic sensitive element may include iron particles mixed with the polymer forming the elongated body, or may be formed by the continuous reinforcing strand including a ferromagnetic sensitive material.

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.
