Abstract
A spoke has a rod and at least one tube. The rod is made of a composite material containing thermoplastic resin and fibers. Each one of the at least one tube is mounted on and around the rod and is heated and pressed with the rod to form at least one engaging recess radially embedded in the rod. The spoke engages the at least one tube and the rod via thermoforming the at least one tube and the rod together.
Claims9
A spoke comprising:
- a rod made of a composite material containing thermoplastic resin and fibers;
- and
- at least one tube, each one of the at least one tube having at least one engaging recess, and each one of the at least one engaging recess radially embedded in the rod.
A manufacturing method for a fiber reinforced thermoplastic spoke comprising:
- a tube assembly step:
- preparing a rod made of a composite material containing thermoplastic resin and fibers and a tube and mounting the tube on and around the rod;
- a thermoforming step:
- heating and pressing the rod and the tube together to deform the rod and the tube together to form at least one engaging recess, radially embedded in the rod for engaging the tube and the rod;
- and
- a finishing step:
- processing the rod to remove rough edges, formed by heating and shaping, on the rod.
