A method of manufacturing a high-pressure tank includes: forming a vessel body including a body portion having a cylindrical shape, a domical portion having a hemispherical shape and provided at an end of the body portion, and a neck portion extending from the domical portion in an axial direction of the domical portion; winding fibers around an outer peripheral surface of the vessel body to form a plurality of fiber layers laminated in a radial direction of the vessel body; and placing, in a mold, the vessel body around which the fibers have been wound, and then injecting a resin onto the neck portion in an axial direction of the vessel body to impregnate the fibers with the resin.

The present invention relates to a method of manufacturing a blade shell member for a wind turbine blade. The method comprising providing a blade mould for the blade shell member and arranging a number of fibre-reinforced layers on a blade moulding surface of the blade mould. A first primer layer is applied on top of the fibre-reinforced layers, at a pre-determined spar cap region. Furthermore, a pre-manufactured spar cap having an upper surface, a lower surface, a first side surface, a second side surface, a first end surface and a second end surface is arranged in the pre-manufactured spar cap on the spar cap region, such that the lower surface of the pre-manufactured spar cap contacts the first primer layer arranged on the spar cap region. A second primer layer is also applied to the upper surface of the pre-manufactured spar cap before the step of infusing the blade moulding cavity with resin and curing it. The present invention further relates to a method of manufacturing a wind turbine blade, comprising the steps of manufacturing a pressure side shell half and a suction side shell half over substantially the entire length of the wind turbine blade and subsequently closing and joining the shell halves for obtaining a closed shell.

Collapsible containers and a method of their manufacture are disclosed herein. The collapsible containers have one or more collapsible wall sections and a stiff upper and lower tier. The wall sections have living hinges and three or more tiers between the hinges. A thermoplastic elastomer layer may join separately made portions of the container together. The containers may be made by molding and overmolding. The containers include inter alia bulk liquid containers, jugs, tubs, baskets, bottles, and food containers. The method of manufacturing includes placing a container component and a matching container body comprising a stiff first tier, a stiff second tier, and a collapsible wall section in a mold; assembling the container body with the container component to close one end of the container body; and overmolding a thermoplastic layer around the container body and the container component.

The invention relates to a method for producing an intraocular lens, including the steps of providing a container which is transparent to electromagnetic radiation and in which a liquid that is curable by the electromagnetic radiation is arranged; irradiating the liquid with a set of images formed by the electromagnetic radiation, which each depict an intraocular lens, with each of the images of the set being radiated into the liquid at a different angle of incidence with respect to a reference plane that extends through the liquid, as a result of which the liquid is cured and the cured liquid forms the intraocular lens, an actuator, a solar module and/or a sensor being arranged in the liquid and the intraocular lens being formed around the actuator, the solar module and/or the sensor.

A composite oil pan for a work vehicle engine and a method of forming the composite engine oil pan include forming a sheet of metal into a first pan and open molding a fiber-reinforced polymer resin onto the first pan forming a second pan. The first pan has a first bottom wall and first peripheral walls extending from edges of the first bottom wall to define a sump, the first peripheral walls terminating in a first peripheral flange. The second pan has a second bottom wall and second peripheral walls abutting the first bottom wall and the first peripheral walls, the second peripheral walls terminating in a second peripheral flange. The first pan defines a thin metal structure with an inner surface extending across the first bottom wall, first peripheral walls and first peripheral flange; the second pan reinforces the first pan without abutting the inner surface.

The present embodiment relates to a composite fibre structure (100) and a method (200) of manufacturing the composite fibre structure (200). The composite fibre structure (100) includes a core (102) and an outer layer (108) enclosing the core (102). The core (102) further includes at least one of a permanent core (104) and a temporary core (106). The permanent core (104) is 3-D printed along with the temporary core (106) to form the core structure (102). The permanent core (104) and the temporary core (106) are placed alternatively along the section, extending throughout the length of the composite fibre structure (100), or the permanent core (104) and temporary core (102) can be alternate along the length of the composite fibre structure (100). The layer (108), made of a reinforcement material, wraps the core (102) to form the composite fibre structure (100).

A method for molding a composite pressure vessel liner to secure a boss to the liner is described. The method comprises providing a moldable liner having an end section with a neck and a port. A boss is positioned around the neck of the liner and the liner is heated and pressure is applied to mold the liner to form to the shape of the boss. The angle of the molded liner secures the boss in place around the liner and it is able to withstand high pressures. A tool for molding the liner and a method for using the tool is also described. The tool comprises a tool body and a pipe having external threads. The tool body abuts the liner and the boss. Winding the pipe exerts pressure on the liner, which when heated, forces the liner to mold to the shape of the boss.

A high pressure obturator for a breech loaded, tube-launched projectile includes a generally annular ring having a central longitudinal axis and a radially inward portion. A flange portion is disposed radially outward of and partially contiguous with the radially inward portion. The flange portion extends axially forward and aft beyond the radially inward portion. The outer diameter of the flange portion decreases linearly from an aft most outer diameter to a forward most outer diameter. The obturator may be formed of a plastic material and include circumferential wraps of a high-strength fiber completely embedded in grooves in the obturator.

A wind turbine blade assembly includes a first blade half and a second blade half fixed to the first blade half, defining a blade interior therebetween. The wind turbine blade assembly includes a shear web includes at least one aperture formed therein. The wind turbine blade assembly includes at least one bulkhead attached to the shear web, wherein the shear web and the at least one bulkhead are disposed in the blade interior.
