1. A variable thickness rim structure made of carbon fiber composite, formed by paving multiple layers of carbon fibers, comprising:
a radially outer ply block that is paved as a radially outer side of the rim structure, the radially outer ply block being of an equal thickness multilayer structure;
an axially outboard ply block that is paved as an axially outboard part of a radially inner side of the rim structure, the axially outboard ply block being of a variable thickness differential layer structure;
an axially inboard ply block that is paved as an axially inboard part of the radially inner side of the rim structure, the axially inboard ply block being of a variable thickness differential layer structure; and
a filling ply block that is paved among the radially outer ply block, the axially outboard ply block, and the axially inboard ply block;
wherein:
a first end of the axially outboard ply block and a first end of the axially inboard ply block extend radially inwards to form an annular connecting flange; and
a second end of the axially outboard ply block extends axially outwards, and a second end of the axially inboard ply block extends axially inwards to form a rim ring together with the radially outer ply block.
