The second joint unit complementarily engages the first joint unit. First and second bonding layers are respectively formed between the first indentation portion and the second joint unit and between the second projection portion and the second joint unit. Waterproof cable assemblies are mounted to the shells.

A laser joining method and device includes a pressure-applying clamping device, which presses a first and a second workpiece against one another at least after the workpieces have been locally plasticized, and a mask having mask structures, which allow laser light to pass only in the region of the bonding contact faces, wherein at least the workpiece facing the laser source is formed by a three-dimensional molded part, which is not planar at least on the first contour side facing the clamping element and/or on the second contour side facing the second workpiece, and wherein the clamping element, with the bearing side thereof for the first workpiece, is adapted to the first contour side of the first workpiece. The mask structures are created on the bearing side of the clamping element facing the first workpiece or on the second contour side of the first workpiece facing the second workpiece.

Provided are a fuel tank made of polyketone and a method of manufacturing the same. The method includes injection-molding an upper cover and a lower cover using an injection-molding machine, placing the upper cover and the lower cover at a relatively high position and a relatively low position, respectively, assembling the upper cover and the lower cover with each other, and bonding contact surfaces between the upper cover and the lower cover to each other using a laser beam. Since the upper cover and the lower cover are formed at the same time and are bonded to each other immediately after being assembled by a machine, it is possible to achieve automated production, mass production and remarkable cost reduction. Further, since the fuel tank has sufficient rigidity due to the rigidity of polyketone without an additional reinforcing member, it is possible to manufacture a lightweight fuel tank.

The present disclosure is directed to a rotor blade assembly for a wind turbine having a first rotor blade segment with a first spar cap segment and a second rotor blade segment with a second spar cap segment. The first and second spar cap segments are arranged together at an interface and are constructed of a composite material. Further, the rotor blade assembly includes a joint assembly at the interface of the first and second spar cap segments. The joint assembly is constructed of a first metal joint secured to the first spar cap segment and a second metal joint secured to second spar cap segment. Moreover, the first and second metal joints are welded together at a weld area.

A vibration welding groove system may include a first component having a joining surface with a groove region, where the groove region comprises a groove formed in the joining surface. The first component includes a base region lacking the groove in the joining surface and a transition region located between the groove region and the base region. The transition region has a tapering of the groove to provide a smooth transition from the groove region to the base region. The vibration welding groove system may further include a second component having a weld leg extending from a main body, where the groove of the first component comprises a shape configured to nudge the weld leg towards a center of the groove during joining of the first component with the second component.

Composite joints and methods of forming composite joints are presented. A composite joint comprising: a first composite component formed of one of a thermoset material or a first thermoplastic material; a second composite component formed of a thermoset material or a third thermoplastic material; a thermoplastic joining film formed of a second thermoplastic material between the first composite component and the second composite component, the second thermoplastic material different from the thermoset material, first thermoplastic material, and third thermoplastic material; and a carbon conductive layer in the thermoplastic joining film.

A vehicle lamp 10 includes a lamp body 11, a sealing material 42, and a lens member 12 and a leg portion 41. A groove portion 31 is formed in the lamp body 11. The sealing material 42 is filled in the groove portion 31. The leg portion 41 is provided on the lens member 12. The leg portion 41 is inserted into the groove portion 31 to thereby fix the lamp body 11 and the lens member 12 together via the seal material 42. A narrow portion 51 is provided at a bottom side of the groove portion 31 and a wide portion 52 is provided at an opening 35 side of the groove portion 31. A gap of the wide portion 52 is wider than the gap of the narrow portion 51. The amount of sealing material 42 used in vehicle lamp 10 is limited while ensuring an easy assemblage.

The structural blank has a plurality of oriented fiber plies in a thermoplastic matrix. The guide has a plurality of random dispersed fibers in a thermoplastic matrix. The guide is affixed to the structural blank by injection molding and over molding the guide onto the structural blank. The article of manufacture can take a number of forms for use in industries such as aircraft, automobiles, motorcycles, bicycles, trains or watercraft.

A composite wall assembly edge joint including a first composite buildup pad having a first tapered section is secured to and extends along a first composite face sheet. A second composite buildup pad having a second tapered section is secured to and extends along a second composite face sheet, wherein the first and second composite buildup pads are positioned between spaced apart first and second composite face sheets. A composite flute core member includes a tapered first portion positioned between and secured to the first tapered section and to the second tapered section. A second portion of the composite flute core member extends in a direction away from the tapered first portion of the composite flute core member and is positioned between, extends along and is secured to the first and second composite face sheets.

A method for assembling a composite wall assembly edge joint including laying up a first composite face sheet, laying up a first composite buildup pad having a first tapered section onto the first composite face sheet and positioning a composite flute core member, including a tapered first portion with a first inclined surface and a second inclined surface. First inclined surface is positioned onto the first tapered section of the first composite buildup pad and a second portion of the composite flute core member extends from the tapered first portion along first composite face sheet. The method also includes laying up a second composite buildup pad having a second tapered section with the second composite buildup pad spaced apart from the first composite buildup pad and having at least a portion of the second tapered section overlying the second inclined surface of the tapered first portion.
