A brake disc structure with composite materials is provided, which includes a disc-shaped inner disk made of a light metal material, and at least two outer disks respectively stacked and combined with the upper and lower surfaces of the inner disk through a metallurgical reaction process. The outer disks are disc-shaped and made of a ferrous metal material. Moreover, an axle hole is opened in the center of each outer disk for being fitted on a hub and penetrates the inner disk, thereby constituting the brake disc structure of composite materials having properties of abrasion resistance and light weight.
