An end effector transports, places and forms a composite ply on a tool having complex tool surfaces. The end effector includes a combination of vacuum and Bernoulli grippers for holding the composite ply while it is being transported and formed, and a set of mechanical actuators that form the composite ply down over the tool surfaces. The Bernoulli grippers allow the composite ply to slip while being held and formed.

The invention relates to a laminating device (10) and a laminating method for laminating at least one layer stack (11), comprising at least one substantially plate-shaped workpiece (11a) and at least one adhesive material layer (11b), by means of pressure and/or heat. The laminating device comprises a lower part (12) and an upper part that can be connected to the lower part (12) in a gas-tight manner. A working chamber (14) which can be opened and closed and which is for receiving the layer stack (11) during lamination is formed between the lower part (12) and the upper part (13). A pressure plate (15) can be moved along a press axis (a-a) in the working chamber (14) between the upper part (13) and the lower part (12). At least one sealing frame (21) is arranged between the lower part (12) and the upper part (13). Multiple pressure chambers that can be separated from one another and actuated as required are arranged in the working chamber (14), wherein multiple clamping points are provided spaced apart from one another in the direction of the press axis (a-a), wherein at least one flexible element is secured on one of the clamping points for separating a first pressure chamber (18), and the moveable pressure plate (15) can be moved via the application or non-application of pressure or negative pressure to said pressure chamber. Given that the flexible gas-tight element divides the working chamber (14) into a first pressure chamber (18) located above the flexible gas-tight element and a second pressure chamber (19) located below the flexible gas-tight element and in which the moveable pressure plate (15) is arranged, wherein the movement of the moveable pressure plate (15) occurs due to a pressure difference between the pressure chambers (18, 19), different operating modes of a laminating device can be performed in one unit.

The disclosure provides a method for forming a core layer for at least one information carrying card, and resulting products. The method includes forming an inlay layout, and dispensing a crosslinkable polymer composition over the inlay layout and contacting the inlay layer so as to form the core layer of the information carrying card. The inlay layout includes at least one inlay layer coupled with a first thermoplastic layer. The first thermoplastic layer comprises a thermoplastic material, and defines at least one hole therein. The at least one inlay layer is disposed at least partially inside a respective hole.

A method for manufacturing an acoustic absorption structure including an acoustically resistive layer, a cellular structure, a reflective layer and a plurality of acoustic elements positioned in cavities produced in the cellular structure. This method comprises steps of depositing fiber plies on a contact surface of the cellular structure, fitting a flexible jacket which covers a stack composed of the acoustically resistive layer, the cellular structure and the fiber plies, which is tightly linked with the deposition surface all around the stack, consolidating the fiber plies to form the reflective layer and the fixing thereof on the cellular structure, with a caul plate being inserted between the fiber plies and the flexible jacket during the consolidation step.

A vacuum probe comprises a sharpened body that is displaceable downward and toward a vacuum bag during vacuum hose quick connection. The sharpened body and a valve element inside the vacuum probe move in tandem until the sharpened body projects outside the vacuum probe. A vacuum pressure applied via the vacuum hose pulls the vacuum bag upwards and towards the projecting sharpened body, which then punctures the vacuum bag, thereby enabling air under the vacuum bag to be evacuated via the vacuum probe as vacuum pressure continues to be applied.

A laminating device and a method for producing a laminate. The laminating device has at least one membrane element. The laminating device has at least one force distributing element, wherein a laminating force which can be transmitted onto a lamination object by the membrane element can be distributed onto at least one sub region of a membrane-side surface of the lamination object via the at least one force distributing element. The at least one force distributing element is held on the laminating device.

A method for enhancing fracture toughness of a composite laminate is disclosed. The method includes fabricating a nanofiber yarn, forming a nanofiber yarn layer by aligning the nanofiber yarn in form of a layer, forming a laminated structure by interleaving the nanofiber yarn layer into a plurality of fabric layers, forming the composite laminate by subjecting the laminated structure to a vacuum infusion process (VIP), and curing the composite laminate. Forming the laminated structure includes stacking a plurality of fabric layers onto each other and placing the nanofiber yarn layer between two fabric layers of the plurality of fabric layers. The VIP includes forming a sealed laminated structure by sealing the laminated structure, forming a vacuumed laminated structure by vacuuming the sealed laminated structure, and introducing a resin matrix into the vacuumed laminated structure.

An absorbent core comprising substantially continuous zones of one or more high fluid distribution structures and discontinuous zones of fluid absorption structures surrounding the one or more high fluid distribution structures, wherein the one or more high fluid distribution structures are arranged to distribute fluid across the absorbent core at a speed that is faster than the speed of fluid distribution across the absorbent core by said discontinuous fluid absorption structures, and wherein said continuous zones extend along a path that is substantially parallel to at least a portion of the perimeter of the core, said portion of the perimeter of the core comprising at least a portion of the sides of the core and one of the ends of the core.

A method for vacuum bag sealing a composite part including: using a composite bagging sheet including a first sealing surface and a first interlocking strip coupled to the first sealing surface of the composite bagging sheet; joining the first interlocking strip with a second interlocking strip coupled to a second sealing surface; and forming a sealed vacuum bag around an uncured composite part positioned between the first sealing surface and the second sealing surface.
