A device for producing a curved fiber preform from a bi- or multidirectional fiber semi-finished product, in particular for an aircraft or spacecraft fuselage component has first lamellae and second lamellae formed to be couplable to one another criss-cross such that they are positioned on a shared plane and thus form a grid. The lamellae at least in part are formed resiliently bendable about an axis intersecting the shared plane such that a local orientation of the lamellae in the grid changes. An adhesion device or structure is formed for temporarily adhering the fiber semi-finished product and is configured such that the local fiber orientation of the fiber semi-finished product also changes accordingly when the lamellae bend.

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.

The present invention relates to an embedding element (76) for embedment in a shell structure of a wind turbine rotor blade (10), the element having a wedge-shaped part (85). The embedding element (76) comprises a fibre material and a binding agent, wherein the fibre material is at least partially joined together by means of the binding agent. The inventive element provides improved structural flexibility and elasticity resulting in less wrinkle formation during blade manufacturing. In other aspects, the invention relates to a method of manufacturing the embedding element (76), to a method of manufacturing a wind turbine rotor blade (10) using the embedding element (76), and to a wind turbine blade (10) obtainable by said method.

In one example, a housing for an electronic device may be disclosed which may include a first multi-layer structure. The first multi-layer structure may include a first layer and a second layer formed on the first layer. Each of the first layer and the second layer may include a plurality of protruding features and a plurality of recessing features on an edge of the first layer and the second layer. At least one of the plurality of recessing features of one layer may intersect at least one of the plurality of protruding features of other layer.

A process and process apparatus for forming a protective coating on a magnetic pole of a permanent magnet motor. The process for forming a protective coating on a magnetic pole of a permanent magnet motor includes: horizontally placing a motor rotor, and controlling to perform, at positions of an inlet and an outlet operating on a vacuum bag in a current state, vacuumization and adhesive injection only on an arc section located at the bottom of the motor rotor; and driving the motor rotor to rotate by a predetermined angle after the adhesive in the arc section is initially cured so as to rotate the next arc section in which no adhesive is injected to the bottom, until all arc sections in the circumferential direction of the motor rotor are injected with the adhesive.

A method of manufacturing a portion of a wind turbine blade is described. The method comprising the steps of: laying up a primary fiber material in a mold; infusing said primary fiber material with a primary resin; substantially curing said primary resin in said primary fiber material to form a cured blade element; laying up a secondary fiber material on top of at least a portion of said cured blade element; infusing said secondary fiber material with a secondary resin different to said primary resin, wherein said secondary resin has a higher strength level than said primary resin; and curing said secondary resin in said secondary fiber material to form an integrated reinforced section on said cured blade element.

A mudguard member for a saddled vehicle covering above a rear wheel, a rear fender as a mudguard member is formed from fiber-reinforced resin. The rear fender has a surface provided with a resin-made reinforcing rib, the surface facing toward the rear wheel. The rear fender is formed in an elongated shape including: a vehicle attached portion that is arranged at a vehicle-front-side; and a length extension portion that extends from the vehicle attached portion toward the rear of the vehicle body. The length extension portion has a top panel and side panels that extend obliquely downward from both vehicle-widthwise sides of the top panel. The reinforcing rib includes: longitudinal ribs that extend from the vehicle attached portion to a vehicle-longitudinal center of the length extension portion; and transverse ribs that are arranged in a grip pattern in conjunction with the longitudinal ribs.

A lacrosse head pocket and a related method of manufacture are provided to facilitate consistent, repeatable and/or custom manufacture of lacrosse equipment. The pocket can be knitted, weaved or otherwise assembled on an automated assembly machine from strands, and/or can be formed as a unitary textile material having regions/sections with different physical and/or mechanical properties. The pocket can be integrally molded within portions of a lacrosse head to eliminate manually constructed connections between the pocket and lacrosse head. The pocket can include a perimeter flange constructed from special materials and/or a perimeter flange including intermittent voids along an outer edge so that the perimeter flange stretches when the pocket is in a loaded state with the lacrosse ball therein, thereby providing dampening to the pocket when a lacrosse ball exerts force upon the pocket in the loaded state.
