A method may comprise: laying up a first plurality of plies of material comprising thermoplastic resin and fiber to form an inner skin preform, the inner skin preform being a continuous sheet including alternating peaks and valleys; laying up a second plurality of plies of material comprising thermoplastic resin and fiber to form an outer skin preform; and joining the inner skin preform to the outer skin preform.

A composite component is a composite component to be fixed to another component. The composite component includes: a first member formed of a first material, and a second member formed of a second material different from the first material, the second member a part of which is covered with the first member. The second member includes a protruding portion protruding in a convex shape from the first member. The protruding portion includes a fixing portion which is provided at least in a part of the protruding portion and to which the other component is to be fixed.

Various methods and assemblies are provided for producing composite components having formed in features. For example, a method may comprise depositing a composite material on a base tool; aligning an aperture forming tool with a tooling aperture in the base tool; inserting the aperture forming tool through the composite material to form an aperture in the composite material; deploying a feature forming tool to press the composite material into one or more recesses; and processing the composite material with the feature forming tool in contact with the composite material. In some embodiments, the feature forming tool includes a stem extending through the composite material and into the base tool, as well as a feature forming head that is brought into contact with and processed with the composite material. In other embodiments, a tooling assembly holds a pin in place during processing to fix the pin in the composite component.

The present invention relates to a structure including a layer including titanium (di)oxide nanostructures, such as titania nanotubes, in contact with a membrane layer including a proton-conducting polymer. A process for preparing the structures of the invention is presented wherein titanium (di)oxide nanostructures on a first substrate are transferred to an ion-conducting polymer membrane by pressing using a hot press, and then detaching the nanostructures from the first substrate.

Methods, systems, and apparatuses of a fluid bubble valve device or element can comprise a plurality of films or webs aligned over the top of each other. For example, two separate webs or film layers of material can be made with two or more different layers of films combined to provide different necessary benefits in manufacturing or forming the valve and sealing to a pouch or package later. The two individual forming webs or film layers are fed into a machine together where channel seals and a bubble pocket are created to form a pathway for a controlled direction for a fluid product to later flow through when the completed pouch or package is used by the consumer. The pocket is formed on both of the two individual forming webs or film layers at the same time. A separate lidding web or layer of material is introduced and sealed over the underside of the bubble pocket to trap air or gas between the lidding layer and the combined individual forming webs or film layers.

A vacuum adiabatic body, a method for fabricating a vacuum adiabatic body, a porous substance package, and a refrigerator including a vacuum adiabatic body and a porous substance package are provided. The vacuum adiabatic body may include a first plate, a second plate, a seal, a support, a heat resistance device, and an exhaust port. The support may include a porous substance and a film made of a resin material, the film configured to accommodate the porous substance therein. Accordingly, it may be possible to provide a vacuum adiabatic body through an inexpensive process.

A syringe includes a syringe body, a syringe cone having a distal opening, and a connection arranged in the region of the syringe cone, wherein the syringe body includes a first material and the connection includes a second material, and wherein the first material is different from the second material and the second material is a softer material than the first material.

The present disclosure is directed to a root assembly for a rotor blade of a wind turbine and methods of manufacturing same. The root assembly includes a blade root section having an inner sidewall surface and an outer sidewall surface separated by a radial gap, a plurality of root inserts spaced circumferentially within the radial gap, and a plurality of spacers configured between one or more of the root inserts. Further, each of the root inserts includes at least one bushing surrounded by a pre-cured or pre-consolidated composite material. In addition, the spacers are constructed of a pre-cured or pre-consolidated composite material.

A fluid leak repair kit, comprising: a putty; a self-amalgamating tape; and a composite material for use in encompassing the self-amalgamating tape, said composite material comprising a flexible sheet or tape and a matrix component for binding the flexible sheet or tape, the matrix component comprising a resin or water-activated matrix component which, when cured, forms an outer shell.
