  • Patent number: 9494185
    Abstract: A support strut for use as a primary load-bearing structural component for the hinged coupling of at least one additional primary load-bearing structural component. The support strut includes: a rod-shaped base body extending in a longitudinal direction, a fiber composite with an annular cross section, central hole originating from the first end of the base body, and with annular holes spaced apart relative to each other in the circumferential direction of the annular cross section and originating from the first end of the base body as well as running along the longitudinal direction in the base body; roving bundles imbedded in a matrix material that fills up the respective annular hole; and a hinged connecting body with a bearing receptacle for holding a swivel joint; as well as a guiding system with such a support strut and a method for manufacturing such a support strut.

  • Patent number: 8591693
    Abstract: The invention relates to a method for joining components (4, 6) made at least partially of thermoplastic material and of which at least one is reinforced with long fibers, wherein the components (4, 6) are welded to each other in a joint zone. The components (4, 6) are thereby welded in the joint zone (8) by means of heat input generated by laser radiation (10), wherein at least one (4) of the components (4, 6) is at least partially transparent to the laser radiation (10) and wherein the laser radiation (10) is at least partially absorbed by at least one (6) of the components (4, 6). According to the invention, the laser radiation (10) is absorbed essentially in fibers and/or in a fiber coating of the component reinforced with long fibers.

  • Patent number: 7972457
    Abstract: A device for draping and pre-shaping curved profiled structural components of fiber materials includes at least one shaping tool having a curved shaping face which has a profiled cross-section and which defines the outer contour of the profiled structural component. The device also includes a plurality of unwinding devices each for discharging a web-like fiber material, a device for performing a relative movement between the shaping tool and the plurality of unwinding devices for tangentially winding the web-like fiber materials onto the curved shaping face under tension, and a fixing device for finally fixing the shape of all of the web-like fiber materials wound on the curved shaping face. A method of draping and pre-shaping curved profiled structural components of fiber materials is also disclosed.
