The spar cap comprises a plurality of strips (138) extending longitudinally in the spanwise direction and arranged side-by-side in the chordwise direction, said strips comprising one or more intermediate strips (158) arranged between peripheral strips (160, 162) which are inclined relative to the intermediate strips. A shear web (126) comprising a flange (130a) extending longitudinally in the spanwise direction is provided, the flange comprising a base (144) defining a primary bonding surface (164). A chordwise width of the primary bonding surface corresponds substantially to a chordwise width of the intermediate strips of the spar cap. The primary bonding surface of the flange is bonded to the one or more intermediate strips of the spar cap.

A composite airfoil is disclosed. In various embodiments, a composite airfoil as disclosed herein includes an outer skin comprising one or more layers of carbon fiber composite material, the outer skin defining an aerodynamic surface having a leading edge; and a reinforcement material comprising a roll of fiberglass reinforced fabric positioned behind the outer skin along at least a portion of the leading edge.

This flexible mandrel for molding a composite material containing a thermosetting resin includes: a main body containing a first material; and a thermally conductive layer containing a second material having a higher thermal conductivity than the first material, the thermally conductive layer being formed so as to cover at least a portion of the main body. The thermally conductive layer extends from a contacting surface of the flexible mandrel, which comes into contact with the composite material during molding, to a non-contacting surface which does not come into contact with the composite material.

This document describes systems and processes for forming improved synthetic molded slabs suitable for use in living or working spaces (e.g., along a countertop, table, floor, or the like).

A padding device (10a; 10b; 10c; 10d; 10e), for a carrying belt system (100) for a respirator (1000), has a closed pad core shell (20) and a pad core (30) configured in the pad core shell. The padding device is formed by injection molding a hollow profiled section, inserting of a pad core material into the hollow profiled section for forming the pad core in the hollow profiled section, and closing the hollow profiled section (21) for creating the closed pad core shell (20). The padding device (10a; 10b; 10c; 10d; 10e) has a closed pad core shell (20) and a pad core (30) arranged in the pad core shell. The pad core shell is seamless as an injection-molded component in at least some sections. A carrying belt system and a respirator with the carrying belt system are provided with the belt system having the padding device.

A system (24) and method are described herein for manufacturing a wind turbine blade (22) proximate to the final installation site of a wind turbine (10). The system (24) includes a creel (72) of feeders (74) configured to apply strengthening elements (62) onto a plurality of shell core sections (26) coupled together and fed through the creel (72). The shell core sections (26) include an external surface (56) with a plurality of external grooves (58) recessed into the external surface (56) such that the strengthening elements (62) are laid into the external grooves (58). The system (24) also includes a deposition station (78) configured to apply an outer surface material layer (82) in fluid form to cover the external surface (56) and the plurality of strengthening elements (62). A curing station (86) heats and consolidates the shell core sections (26), the strengthening elements (62), and the outer surface material layer (82) together into a final consolidated part, with the outer surface material layer (82) defining an external profile of the blade (22) following curing.

A bonding tool is described that is used to secure sacrificial pads to bonding locations on a perimeter of a rib during a bonding process. In one embodiment, the bonding tool includes a base member having a rib receptacle dimensioned to receive a rib of a wing, a plurality of compression forms disposed around at least a portion of the rib receptacle and proximate to a perimeter of the rib, where the compression forms include a plurality of sacrificial pads that face towards bonding locations on the perimeter of the rib, and at least one bladder proximate to the compression forms that expands between a wall of the base member and the compression forms to press the sacrificial pads against the bonding locations while the sacrificial pads bond to the bonding locations.

A method of making a sealing article that includes a body and a coating layer disposed on at least one surface of the body. The body comprises a polymeric elastomer such as perfluoroelastomer or fluoroelastomer. The coating layer comprises at least one metal. The sealing article may be a seal, a gasket, an O-ring, a T-ring or any other suitable product. The sealing article is resistant to ultra-violet (UV) light and plasma, and may be used for sealing a semiconductor processing chamber.

A method for positioning wrinkling of a cured composite material at a predetermined location in fabricating a composite part, which includes positioning a caul plate in contact with an uncured composite material. The uncured composite material has a geometric change in shape and the caul plate has a first slit which extends through and along the caul plate. The method further includes positioning a fiber and a resin of a portion of the uncured composite material within the first slit and curing the uncured composite material positioning a wrinkle within the first slit of the caul plate.

A shaving razor with an angled wash through channel. A razor blade is sandwiched between a base member and a blade cover. The based member is unitarily molded to include an integral blade guard that resides ahead of a cutting edge of the razor blade in a cutting direction, the base member also defines a wash through channel opening at an angle in the range of 30-70 degrees.
