Carbon fibre reinforced plastic bicycle rim with ceramic brake portion

According to the present invention, a carbon bodied bicycle rim with ceramic brake portion (1) comprises a carbon bodied bicycle rim (10) and a protective film (A) thermal sprayed on the carbon bodied bicycle rim (10). The carbon bodied bicycle rim (10) includes two brake portion (11) respectively formed on two sides thereof. Each brake portion (11) has an outer surface (111). The protective film (A) is thermal sprayed on the outer surface (111) of the brake portion (11), by which the brake portion (11) has a characteristic of wear-resisting and thermal dissipation. The protective film (A) includes an aluminum layer (20) thermal sprayed on the brake portion (11) and a ceramic layer (30) thermal sprayed on the aluminum layer (20).
