A composite rim for a bicycle wheel that has a wall of structural fibers incorporated in a thermosetting polymeric material and a plurality of spoke attachment seats. The composite material includes at least one layer of woven bi-directional fibers where some fibers are in a nominal direction substantially parallel to the circumferential direction of the rim and some fibers are substantially orthogonal to the circumferential direction of the rim.

The present invention discloses a carbon fiber spoke and a manufacturing method thereof. The carbon fiber spoke includes a spoke body made of carbon fiber, a screw bushing that is fit and connected with rim and a nut cap bushing that is fit and connected with the hub. Two end parts of the spoke body are provided with solid joints. The outside surface of the solid joint is provided with a first tapered section. The screw bushing and the nut cap bushing are provided with penetrable mounting holes. The hole wall surrounding the mounting hole is provided with a second tapered section. The mounting hole of the screw bushing and the mounting hole of the nut cap bushing are respectively fixed to the two solid joints; the second tapered section of the mounting hole and the first tapered section of the solid joint are fit and connected together.

A non-metallic rim for a wheel which may be used for motorised vehicles. The rim has a barrel, a first flange, a second flange, a first bead seat, a second beat seat and a primary structural component. The primary structural component extends into at least the first flange and the barrel, and the primary structural component is capable of bearing the majority of the radial and/or lateral load that is borne by the rim during usage. Additionally, the rim has at least a portion of the first bead seat spaced apart from the primary structural component and/or has a protective insert in between the outer face of the first flange and the primary structural component.

A composite article includes a first segment and a second segment spaced apart form the first segment. The composite article includes continuous fibers that extend from the first segment to the second segment. The composite article also includes discontinuous fiber distributed throughout the composite article.

The invention relates to a method for producing a wheel rim having a rim base of a fiber composite material. The problem to be solved by the invention is that of improving the production of the wheel rim, and especially to ensure a reliably functioning wheel structure which can be achieved with little financial and technical outlay. The problem is solved in that during the production of the rim base (2) a connection element (3, 13, 21, 31, 42, 51) is joined to the rim base (2), said connection element (3, 13, 21, 31, 42, 51) being designed and arranged in such a way that a wheel disc (4, 14, 22, 36, 45) can be connected to said connection element (3, 13, 21, 31, 42, 51).

In a method for manufacturing a spoke unit, the continuous fiber reinforced plastic is led from a middle supporting portion to a first supporting portion along the front surface of the mandrel. Subsequently, the continuous fiber reinforced plastic is led from the first supporting portion to the middle supporting portion along the back surface of the mandrel. Subsequently, the continuous fiber reinforced plastic is led from the middle supporting portion to a second supporting portion along the front surface of the mandrel. Subsequently, the continuous fiber reinforced plastic is led from the second supporting portion to the middle supporting portion along the back surface of the mandrel.

A method for making a carbon fiber wheel rim includes: preparing an outer supporting piece; winding a carbon-fiber yarn around the outer supporting piece to form carbon fiber layers and to constitute an engaging seat preform; connecting an inner supporting piece to the engaging seat preform; connecting a reinforcement piece to the inner supporting piece; winding a carbon-fiber yarn around an assembly of the engaging seat preform, the inner supporting piece and the reinforcement piece to form carbon fiber layers; fixing the assembly with the carbon fiber layers to form an outer frame preform; and cutting the outer frame preform and the engaging seat preform to form a trench and removing the outer supporting piece therefrom.
