Abstract: Provided is a high heat resistant brake disk for a railroad vehicle, which is manufactured using a nano material having high heat conductivity, such as a carbon nanotube (CNT) or graphene, to improve heat resistance of an overheated portion of the brake disk, and which can extend a life of the brake disk by suppressing performance deterioration due to a thermal shock. The high heat resistant brake disk includes a hub inserted into an axle of the railroad vehicle and an outer circumference coupled to a vehicle wheel to coaxially rotate with the vehicle wheel, wherein at least one pattern unit made from a high heat resistant nano material is formed on one surface of the brake disk.
