Clip includes a clip body provided with an accommodating space extending in a front-rear direction, and left and right wings coupled to the clip body in a left-right direction orthogonal to the front-rear direction. Each of the left and right wings includes front edge and rear edge which extend away from the clip body along the left-right direction. In one or both of the left and right wings, the front edge slants linearly or non-linearly forward of the clip as the front edge extends away from the clip body.

Methods and systems are provided for fabricating a composite structure. In one example, the composite structure may include a honeycomb core sandwiched between face sheets. An edge of the honeycomb core may be abraded and a top face sheet may be perforated. As such, a likelihood of delamination of the composite structure during a curing step may be reduced.

A light weight hybrid torque transfer joint trunnion has an integral metal hub spline fitting oriented on a center axis. This integral metal hub spline fitting may be made of steel, aluminum, titanium, or the like and may be generally cylindrical. The integral metal hub spline fitting defines an integral central internally-splined mast or driveshaft coupling opening centered about the center axis. A composite material body centrally retains, and is cured to, the metal hub spline fitting. Torque transfer joint link attachment pins extend from the composite material body and are rigidly linked to the metal hub spline fitting. In an example constant-velocity joint, a plurality of pivoting linkages may each be rotatably coupled to the torque transfer joint link attachment pins, and each of the plurality of pivoting linkages may, in turn be secured to a rotor yoke configured to mount a plurality of rotorcraft blades.

A tie rod that includes a central section, a first tapered section, and a second tapered section. A thermoplastic tube extends the length of the tie rod. The first tapered section includes a first insert positioned within the thermoplastic tube. The second tapered section includes a second insert positioned within the thermoplastic tube. A channel extends through the tie rod along the central section, the first tapered section, and the second tapered section.

A method of manufacturing a composite member including an aluminum member and a fiber-reinforced resin member bonded to each other, the method including: performing blasting on a surface of the aluminum member; modifying the surface of the aluminum member into aluminum hydroxide, the modifying including causing the surface of the aluminum member having undergone blasting to react with water by using at least one of heat and plasma; and directly bonding the fiber-reinforced resin member to the surface of the aluminum member modified to the aluminum hydroxide.

In a state in which an insert (310) is embedded in an embedding opening of a panel (300) and a nozzle (211) of a dispenser (210) is located above an injection hole of the insert, an air cylinder (230) presses an edge of a discharge port (212) of the nozzle on an edge of the injection hole of the insert. Subsequently, the dispenser discharges an adhesive from the discharge port of the nozzle. The adhesive is injected from the injection hole of the insert, and fills a gap between the insert and the panel. Therefore, the insert is fixed to the panel.

Clip includes a clip body provided with an accommodating space extending in a front-rear direction, and left and right wings coupled to the clip body in a left-right direction orthogonal to the front-rear direction. Each of the left and right wings includes front edge and rear edge which extend away from the clip body along the left-right direction. In one or both of the left and right wings, the front edge slants linearly or non-linearly forward of the clip as the front edge extends away from the clip body.

A flask stand is configured to support a flask and includes a base ring and a plurality of legs. The base ring is configured to support a lower portion of the flask. Each leg is secured to the base ring and extends outward from the base ring. Each leg includes a body, a lattice, and an elastomeric foot. The body includes a first end portion that is secured to the base ring with the foot portion being opposite the first end portion. The lattice is formed within the foot portion and includes a plurality of members that form an open-mesh frame that defines a plurality of voids between adjacent members of the frame. The elastomeric foot is formed of an elastomer and is disposed about the lattice and within the voids of the lattice. The foot is configured to engage a surface to support the body relative to the surface.

A tube arrangement includes a composite tube defining a centerline axis, wherein the composite tube comprises a proximal surface and a distal surface, and an end fitting comprising a first end disposed within the composite tube and a second end extending from the composite tube, wherein an outer surface of the end fitting defines a flared portion defining a terminus of the first end, a lobe portion disposed axially from the flared portion, and a terminating portion disposed axially from the lobe portion, the proximal surface conforms to a geometry of the outer surface of the end fitting, the lobe portion and the flared portion mechanically lock the end fitting to the composite tube to mitigate movement of the end fitting relative to the composite tube.

A method for producing a component made of fiber-reinforced plastic includes comprises the steps of providing at least one insert part, placing the insert part in a mold and embedding the insert part using a matrix material and at least one fiber mat in the mold. The insert part is provided as a closed capsule.
