The High TG carbon fiber adapted technology is as well as a manufacturing method thereof. The wheel/rim is manufactured from carbon fiber composite materials, and comprises two crossed side walls and a connecting axle; a tire position hole slot for placing an inner tire and a 'U'-shaped inner cavity body are formed in two border areas of the connecting axle in a spacing manner, and the tire position hole slot and the 'U'-shaped inner cavity body are ranked up and down; side walls, corresponding to and close to the tire position hole slot and the connecting axle, are braking sides; the braking sides and the connecting axle combine to form a structure with an 'H'-shaped cross section; high TG epoxy resin carbon fiber materials are adopted for the 'H'-shaped structure and the side wall corresponding to the inner cavity body.  epoxy resin carbon fiber materials with high-TG higher than 240 DEG C are adopted for the braking area for bearing tire pressure, and the frame burning hazard of the rim is reduced effectively.
