An article comprising: (a) a carrier having a predetermined shape to guide one or more expansion directions of an injection molded expandable material; (b) the injection molded expandable material on the carrier; wherein the expandable material is formed on the carrier at one or more angles perpendicular to the one or more expansion directions; and wherein the expandable material is capable of being activated to expand under an activation condition to come into contact with, and adhere to one or more walls defining a cavity in order to at least partially fill the cavity.

A lacrosse head pocket and a related method of manufacture are provided to facilitate consistent, repeatable and/or custom manufacture of lacrosse equipment. The pocket can be constructed from multiple different sections joined with one another, or can be knitted, weaved or otherwise assembled on an automated assembly machine from strands, and/or can be formed as a unitary textile material having regions/sections with different physical and/or mechanical properties. The pocket can be integrally molded within portions of a lacrosse head to eliminate manually constructed connections between the pocket and lacrosse head. The lacrosse head can be integrally molded with a lacrosse handle to provide a one-piece unitary lacrosse stick. The lacrosse pocket body can include one or more fused pocket areas. Related methods of manufacturing also are provided.

A manufacturing method comprises: providing a woven fabric comprising a plurality of reinforcing fibre tows and a plurality of thermoplastic polymer yarns woven together; and moulding the woven fabric in a heated mould to form a preform for a composite component.

An insulating element for insulating a structural element in a vehicle including a carrier element having an edge region and an expandable material which is provided at least on the edge region on the carrier element. The expandable material projects beyond the edge region of the carrier element in at least one direction so that the expandable material forms a flexible projection in this at least one direction.

The invention relates to a process for the production of finished parts made of at least one multilayer, fiber-reinforced, flat semifinished-product structure, comprising the following steps: a) heating of the at least one multilayer, fiber-reinforced, flat semifinished-product structure at ambient pressure to a first temperature T.sub.a, where the at least one multilayer, fiber-reinforced, flat semifinished-product structure comprises at least two mutually superposed polymer layers and the individual polymer layers respectively have fiber-reinforcement and do not have coherent bonding to one another or have only partial coherent bonding to one another, and in the event that at least one of the polymer layers comprises a semicrystalline polymer the first temperature T.sub.a is higher than a melting point T.sub.m of the crystalline polymer in accordance with DIN EN ISO 11357-3:2013-04, and in the event that the at least two polymer layers comprise no semicrystalline polymer the first temperature T.sub.a is higher than a glass transition temperature T.sub.g in accordance with DIN EN ISO 11357-2:2013-09 of a polymer comprised in at least one of the at least two polymer layers, b) pressing of the heated at least one multilayer, fiber-reinforced, flat semifinished-product structure to give a finished part at a second temperature T.sub.b and at a pressure p.sub.b of at least 3 bar.

A brush head (32) including: a supporting portion (42) of a brush neck (40); a plurality of bristle tufts (21), each of which comprises a plurality of bristle strands having a proximal end (23) and a free end (25), wherein each of the plurality of bristle tufts comprises a proximal end head portion (26) melted into a first shape within a mold; and an elastomeric matrix (30) comprising at least a portion of the hard brush neck and the proximal end head portions, wherein the first shape of the proximal end head portion is configured to engage the elastomeric matrix such that the bristle tufts are retained within the elastomeric matrix.

A lacrosse head pocket and a related method of manufacture are provided to facilitate consistent, repeatable and/or custom manufacture of lacrosse equipment. The pocket can be constructed from multiple different sections joined with one another, or can be knitted, weaved or otherwise assembled on an automated assembly machine from strands, and/or can be formed as a unitary textile material having regions/sections with different physical and/or mechanical properties. The pocket can be integrally molded within portions of a lacrosse head to eliminate manually constructed connections between the pocket and lacrosse head. The lacrosse head can be integrally molded with a lacrosse handle to provide a one-piece unitary lacrosse stick. Related methods of manufacturing also are provided.

A life ring includes a cover formed of a knitted back polyester fabric with a top vinyl coating, and a urethane foam core within the cover. The cover and the urethane foam core are formed into a ring shape. By using the noted cover material, the life ring can be manufactured without a painting step, thereby reducing manufacturing costs and improving the consistency of the finished product.

A high-pressure tank comprises a liner, a strengthening layer including a first helical layer and a first hoop layer each including a carbon fiber, and a protective layer including a second helical layer and a second hoop layer each including a glass fiber, in this order. The high-pressure tank is provided with a stress-generating portion, a reinforcement layer includes a first area overlapping the stress-generating portion in a stacking direction and a second area that is an area except for the first area, and a one-round portion including a final crossing portion at an end of winding of the glass fiber constituting the second hoop layer overlaps the second area in the stacking direction.

A brush head (32) including: a supporting portion (42) of a brush neck (40); a plurality of bristle tufts (21), each of which comprises a plurality of bristle strands having a proximal end (23) and a free end (25), wherein each of the plurality of bristle tufts comprises a proximal end head portion (26) melted into a first shape within a mold; and an elastomeric matrix (30) comprising at least a portion of the hard brush neck and the proximal end head portions, wherein the first shape of the proximal end head portion is configured to engage the elastomeric matrix such that the bristle tufts are retained within the elastomeric matrix.
