The invention relates to a method for producing a component bond (70, 140) comprising: a fastening structure (60, 160) that has at least one component layer (60; 160a, 160b); and a thermoplastic connecting element (10, 110) having a head (12) and a shank (14), in which method the connecting element (10, 110) is driven into the fastening structure (60, 160) under pressure whilst rotating, such that the shank (14) penetrates the fastening structure (60, 160). The connecting element (10, 110), after penetrating the fastening structure (60, 160), is converted by friction into a softened, free-flowing state in a die (44, 144) which is placed against the fastening structure (60, 160) in the opposite direction to the driving direction, resulting in a thicker section (22, 22) that extends beyond the radial extent of some sections of the shank (14). The fastening structure (60, 160) is thus interlockingly held between the head (12) and the thicker section (22, 122).

A connecting joint for attaching a wind turbine rotor blade to a rotor hub includes a bolt having a blade end configured to be coupled to the rotor blade and a hub end configured to be coupled to the rotor hub. The bolt includes a neck region adjacent the blade end, wherein the neck region has a cross dimension less than a cross dimension of the blade end of the bolt. A wind turbine blade having such a connecting joint is also disclosed. Additionally, a method of making the connecting joint is disclosed.

A connecting joint for attaching a wind turbine blade to a rotor hub includes an insert configured to be coupled to the wind turbine blade. The insert includes a main body having an outer surface configured to interface with the blade, a first tubular extension extending from the main body and having inner and outer surfaces configured to interface with the blade, and a second tubular extension extending away from the main body and having inner and outer surfaces configured to interface with the blade. A wind turbine blade having such a connecting joint is also disclosed. Additionally, a method of making a wind turbine blade including the connecting joint is disclosed.

A method for manufacturing a thrust reverser blocker door may comprise thermoforming a sandwich panel comprising a facesheet, a backsheet, and a honeycomb core. The method may further comprising overmolding a mounting structure onto the backsheet. The first thermoplastic material may comprise a continuous fiber reinforced thermoplastic composite material. The second thermoplastic material may comprise a discontinuous fiber reinforced thermoplastic composite material.

A method of welding a protective structure to a tip of a surgical laser fiber involves inserting the optical fiber into a length of tubing, and positioning the fiber and the tubing in a rotatable fixture arranged to simultaneously rotate the fiber and tubing while laser radiation is directed through a transparent material of the tubing, so that one or both contacting surfaces of the tubing and the fiber absorb the laser radiation and heat up to weld the tubing to the fiber. The tubing may be a length of polymer material.

Provided is a soft container in which a tip portion of a body portion can be blocked with one member. The tip portion of a flexible body portion 10 of a soft container 1 is blocked by a tip sheet member 20. The tip sheet member 20 integrally has a circumferential side portion 21, a shoulder portion 22, and a top portion 23. The tip sheet member 20 is constituted by a self-supporting film molded body 28 having a uniform thickness. The tubular circumferential side portion 21 and the body portion 10 are joined to each other. The shoulder portion 22 is reduced in diameter in a tapered shape from the circumferential side portion 21 toward the tip side. The top portion 23 blocks the tip portion of the shoulder portion 22.

The present invention concerns a method of bundling a plurality of monofilaments into a bundle of monofilaments by means of a laser, a paint brush head including such bundle of monofilaments and a paint brush including such paint brush head.

A separating film with an anti-adhesion layer for preventing an adhesive connection between a thermally curable levelling compound, applied in the region of a joining zone of a first component, and a joining zone of a second component to be joined to the first component. The anti-adhesion layer is provided, at least in parts, with a heating layer. As a result of the actively electrically heatable heating layer of the separating film, which is an integral part of the separating film, the processing time for joining two components, which are subject to tolerances, using a thermally curable levelling compound (known as liquid shimming), can be reduced by at least 40% compared with the conventional process.

A composite duct with reinforcement comprises an inner ply, an outer ply, and a plurality of cellular core rings. The inner ply forms a channel with a circular cross-section. The plurality of cellular core rings is positioned at set intervals along a length of the composite duct and between the inner ply and the outer ply.

A system for forming a tendon sleeve on an atmospheric balloon is described herein, the system comprising a coupling assembly including a seam coupling mechanism that forms a seam joint between a first gore panel and a second gore panel, the seam joint is spaced from respective first and second lateral edges of the first and second gore panels to form first and second edge flanges, and an edge coupling mechanism that forms an edge joint between the first and second edge flanges and closes a tendon sleeve, the edge joint spaced from the seam joint, the tendon sleeve includes a tendon sleeve passage between the seam joint and the edge joint and between the first and second edge flanges. The system also includes a tendon positioning mechanism that positions a tendon within the tendon sleeve passage. A tendon sleeve formed by this system is also described herein.
