Abstract
A spoke has a carbon rod and at least one connecting unit. The carbon rod is made of a composite material containing thermoplastic resin and carbon fibers and has at least one blocking portion. Each one of the at least one connecting unit has a tube mounted on and around the carbon rod and blocked by a corresponding one of the at least one blocking portion. The carbon rod is heated and shaped to form the blocking portion. The spoke in accordance with the present invention blocks the connecting unit by the blocking portion to promote a connection stability of the spoke.
Claims14
A spoke comprising:
- a carbon rod made of a composite material containing thermoplastic resin and carbon fibers and having at least one blocking portion;
- at least one connecting unit, each one of the at least one connecting unit having a tube mounted on and around the carbon rod and blocked by a corresponding one of the at least one blocking portion;
- wherein the carbon rod is heated and shaped to form the at least one blocking portion.
A manufacturing method for a carbon fiber reinforced thermoplastic spoke comprising
- a connecting unit assembly step:
- preparing a carbon rod made of a composite material containing thermoplastic resin and carbon fibers and a connecting unit having a tube and mounting the tube on and around the carbon rod;
- a blocking portion formation step:
- heating and shaping the carbon rod to form a blocking portion for blocking the tube of the connecting unit;
- and
- a finishing step:
- processing the blocking portion to remove rough edges, formed by heating and shaping, on the blocking portion.
