A fiber placement system including a fiber placement station at a first location, the fiber placement station including a tool and a fiber placement assembly configured to construct a reinforcement layup on the tool, the first fiber placement assembly including a compaction roller rotatable about an axis of rotation, the compaction roller at least partially defining a nip, a thermoplastic composite ply extending through the nip and a heating unit positioned to heat the thermoplastic composite ply proximate the nip, and a consolidation station at a consolidation location, the consolidation location being different from the first location, the consolidation station including a consolidation tool and a consolidation system configured to consolidate a reinforcement layup assembly that includes the reinforcement layup.

A connector is formed by fixing two or more connector parts each made from a resin to each other by press fitting or with an adhesive. At least one weld part regulating thermal deformation between the connector parts is formed in a boundary portion between the adjoining connector parts.

A joint structure comprising a light-absorbable member having at least one opening portion and a light-permeable member superposed on the light-absorbable member so as to cover the opening portion, wherein an annular weld part is formed so as to enclose the opening portion and join the light-absorbable member and the light-permeable member, and an area ratio of a portion at the side of the light-absorbable member to a portion at the side of the light-permeable member side is in a range of 12-35 viewing a section perpendicular to the extending direction of the annular weld part.

The present disclosure relates more to processes for making a filter element that includes a filter membrane having a strip of thermoplastic polymer material laminated thereto, for example, as a strip along an edge of the filter membrane. For example, one such process includes providing a sheet of filter membrane having a first surface and an opposed second surface; providing a strip of thermoplastic polymer material having a first surface and an opposed second surface; contacting the first surface of the strip of thermoplastic polymer material with the first surface of the filter membrane; and softening the strip of thermoplastic polymer material at at least its first surface by irradiation with laser radiation; such that the softened polymer material of the first surface of the strip of thermoplastic polymer material bonds to the first surface of the filter membrane upon hardening.

A joint structure comprises a light-absorbable member having at least one opening portion and a light-permeable member superposed on the light-absorbable member so as to cover the opening portion, wherein a first annular weld part is formed so as to enclose the opening portion and join the light-absorbable member and the light-permeable member, and a second dot-like weld part(s) joining the light-absorbable member and the light-permeable member is/are formed in a position adjacent to the first weld part.

The present invention relates to a process for laminating a first substrate, which comprises a thermoplastic polymer material surface, and wherein the first substrate preferably is a thermoplastic polymer film, to a second substrate, wherein the second substrate preferably is a non-woven or woven fabric, wherein the thermoplastic polymer material surface is activated by irradiation with a laser beam prior to laminating the two substrates to each other as well as a device for carrying out such a process.

In the present invention, one surface of a belt-shaped sheet laminate (10), in which a plurality of sheets are laminated, is pressed against a support member (21) having a light passage section (27) through which a laser beam (30) can pass, and the belt-shaped sheet laminate (10) is irradiated, from the support member (21) side via the light passage section (27), with a laser beam (30) to cut and fusion-bond the belt-shaped sheet laminate (10), thereby sealed edge sections (4) are formed by fusion-bonding the edge sections of the plurality of sheets.

A vent structure includes: a first housing component having an opening portion for ventilation; a gas-permeable membrane that is attached to the first housing component to close the opening portion; and a laser welding portion that joins the first housing component with the gas-permeable membrane. The gas-permeable membrane includes a main body including a fluororesin film and a porous resin sheet that is laid on the main body. The porous resin sheet is located on the surface side of the vent structure. Both of the main body and the outer peripheral portion of the porous resin sheet that projects outwardly from the main body are fixed to the first housing component by the laser welding portion.

Method for manufacturing a cell-like honeycomb structure, formed from a plurality of thermoplastic sheets attached to each other, wherein contoured areas are provided in each sheet, and each free sheet is attached to an adjacent sheet of an intermediate block formed by the different sheets previously attached therebetween, welding at least some of the flat areas contacting this free sheet and this adjacent sheet with a laser source along a continuous line parallel to the contour axis.
