Abstract
A variable thickness rim structure made of carbon fiber composite includes an outer ply block, that is paved as an outer side of the rim structure; an upper ply block, that is paved as an upper part of an inner side of the rim structure; a lower ply block, that is paved as a lower part of the inner side of the rim structure; a filling ply block, that is paved among the outer ply block, the upper ply block, and the lower ply block, where a first end of the upper ply block and a first end of the lower ply block extend inwards to form an annular connecting flange; a second end of the upper ply block extends upwards and a second end of the lower ply block extends downwards to form a rim ring together with the outer ply block.
