Abstract
The present disclosure provides an integrally formed carbon fiber spoke and a manufacturing method thereof. The method includes manufacturing a carbon fiber core body and a first metal part and a second metal part at two ends; winding or wrapping the carbon fiber core body and the metal parts at the two ends with carbon fiber prepregs to form a semi-finished product; and putting the wound or wrapped semi-finished product into a forming mold for heat forming. In the present disclosure, the metal parts are wound or wrapped with the carbon fiber prepregs, such that sandwich structures are formed between the metal parts and carbon fiber materials to expand a bonding force of bonding interfaces.
