Abstract
A bicycle wheel rim made at least partially of a stratified composite material comprising structural fibers incorporated in a polymeric matrix. At least one opening, which passes through at least one first layer of composite material, is provided and at least one spoke attachment hole, which passes through at least one second layer of composite material, is also provided. The spoke attachment hole is completely contained within the opening in the first layer. A related manufacturing process is also described.
Claims12
A bicycle wheel rim at least partially made of layers of a stratified composite material comprising structural fibers incorporated in a polymeric matrix,
- wherein at least one opening passes through at least one first layer of the stratified composite material,
- wherein at least one spoke attachment hole has a perimeter defined by (i) at least one second layer of the stratified composite material, or (ii) at least one patch provided in said at least one second layer and that partially closes said at least one opening, and wherein said at least one spoke attachment hole is completely contained in said at least one opening when looking in a direction of an axis common to said at least one opening and said at least one spoke attachment hole.
