Presented are hybrid metal and fiber-reinforced polymer (FRP) composite wheels for vehicle wheel assemblies, methods for making/using such wheels, and motor vehicles equipped with such wheels. A wheel for a motor vehicle wheel assembly includes a wheel face with multiple spokes that are circumferentially spaced about and project radially outward from a central hub. The central hub rotatably attaches to the vehicle's body, e.g., via a corner module. The wheel face is fabricated, e.g., as a one-piece structure, from an FRP material. A wheel barrel, which circumscribes the wheel face, includes an annular rim that mounts thereon an inflatable tire. The wheel barrel is fabricated, e.g., as a one-piece structure, from a metallic material. Multiple overmold through holes and/or inset tabs are circumferentially spaced about the annular rim. The FRP material extends through and/or surrounds the overmold through holes/inset tabs and thereby mounts the wheel face to the wheel barrel.

Devices, systems, and methods of improving paste flow during the manufacture of wind turbine blades are provided. When the first turbine blade half is aligned with the second turbine blade half, a gap is formed between the first shell and the bond cap. The assembly includes a first mold half corresponding to the first turbine blade half and a second mold half corresponding to the second turbine blade half. When the first mold is aligned with the second mold, a second gap is formed. A first barrier is disposed within the first gap and a second barrier disposed within the second gap thereby fluidly sealing a volume defined by the first gap and the second gap to direct adhesive paste flow along the blade span between the adjoining leading and trailing edges.

A method of manufacturing a cured composite structure includes placing a radius filler element into a radius cavity extending along a length of a composite base member. The radius filler element is formed of a permeable material. The method also includes absorbing resin from the composite base member into the permeable material of the radius filler element. The method additionally includes curing or solidifying the resin in the radius filler element and in the composite base member to form a cured composite structure in which the resin bonds the radius filler element to the composite base member.

Embodiments of the present disclosure provide a manufacturing method of a mask plate. The manufacturing method of the mask includes: embedding a shaping mold in a mask region of a mask sheet; fixing the mask sheet with the shaping mold; performing a stretching process on the mask sheet fixed with the shaping mold; and separating the mask sheet from the shaping mold to form the mask.

A pipe fitting having a first body and a second body that together at least partially define a fluid flow passage. The first body defines a first portion of the fluid flow passage that extends from a first end of the fluid flow passage to a first internal opening. The second body defines a second portion of the fluid flow passage that extends from a second internal opening to a second end of the fluid flow passage. The first body has a first interface surface that surrounds the first internal opening, the first interface surface having a plurality of anti-rotation grooves. The second body has a second interface surface that surrounds the second internal opening and engages with the first interface surface. The first internal opening is in fluid communication with the second internal opening. The second interface surface has a plurality of anti-rotation fingers that are each received by and engage with a corresponding one of the anti-rotation grooves. Rotation of the second body relative to the first body is resisted by the engagement of the anti-rotation fingers with the anti-rotation grooves.

A cylindrical winding body is formed by winding continuous fibers impregnated with a first thermosetting resin in a circumferential direction, and the first thermosetting resin in the winding body is thermally cured. A pair of dome members is joined to both end portions of the cylinder member. A fiber bundle impregnated with a second thermosetting resin is helically wound around the joined member over the dome members, and the second thermosetting resin in the wound fiber bundle is thermally cured. A thermosetting resin containing a main agent and a granular solid curing agent is used as the first thermosetting resin, the main agent including a resin precursor and the solid curing agent chemically bonding molecules of the resin precursor together.

A method and system are disclosed. A method of printing onto a base having an upper surface spaced from a lower surface by a base thickness includes dispensing a yarn from a nozzle of a printing system and selectively attaching the yarn to a first attachment region. The step of dispensing the yarn includes dispensing a heat-moldable material and a melt-resistant material. The step of selectively attaching the yarn to the first attachment region includes moving the nozzle into the first attachment region. The step of moving the nozzle into the first attachment region reduces the base thickness by a prodding distance. The heat-moldable material bonds to the first attachment region.

A dispenser apparatus for a curable liquid material is disclosed. The apparatus comprises a flexible bag defining a first compartment for accommodating a first component of a curable liquid material, and a second compartment for accommodating a second component of the curable liquid material and adapted to communicate with the first chamber to enable mixing of the first and second components to initiate curing of the curable liquid material. A first clamp temporarily prevents mixing of the first and second components, and an elongate nozzle communicates with the second compartment to dispense the mixed curable liquid material therefrom. A second clamp temporarily prevents passage of the curable liquid material from the second compartment to the nozzle.

A method of manufacturing a cured composite structure includes placing a radius filler element into a radius cavity extending along a length of a composite base member formed of dry fiber material comprised of reinforcing fibers. The radius filler element is formed of a radius filler material. The method also includes infusing resin into the dry fiber material, and chemically reacting the resin with the radius filler material to create a mixture of resin and radius filler material along side surface interfaces between the radius filler element and the composite base member. The method additionally includes curing or solidifying the resin, and allowing solvent in the resin to evaporate causing hardening of the mixture and bonding of the radius filler element to the composite base member, and resulting in a cured composite structure.
