Wheel made out of fiber reinforced material and procedure to make such wheel

A method for making ef a wheel (1) comprising a rim (2) and a wheel center (3) made from a fiber reinforced composite material, said wheel center (3) comprising a tubular middle section (6) having a center opening (7) extending in the direction of a wheel axis (19) and having a first and a second end (8, 9) and a hub (5) comprising a first flange ring (10) and a second flange ring (11) wherein at least one of the flange rings (10, 11) and the tubular middle section (6) are interconnected to each other by a form fit interconnection (12, 13), wherein the wheel center comprises spokes (4) interconnecting the rim (2) and the tubular middle section (6), wherein said spokes (4) are hollow and communicate with the tubular middle section (6) through an mouth (24), the method comprising the following method steps:

• a. providing at least one auxiliary body corresponding at least partially to the inside of at least one hollow spoke (4);
• b. providing a mold comprising a cavity corresponding at least partially to the outside of the wheel (1);
• c. applying reinforcing fibers to the auxiliary body and/or the cavity;
• d. inserting the at least one auxiliary body into the cavity of the mold along with the reinforcing fibers;
• e. closing the mold and applying and/or curing a matrix material in which the reinforcing fibers are embedded;
• f. removing the wheel from the mold;
• and
• g. removing the at least one auxiliary body from the hollow spoke (4) across the mouth (24) through the center opening (7) of the wheel center (3).
