%X Graphite die is a critical component in material processing, especially at high temperature. However, its strength is a bottleneck. In this study, we propose a novel, efficient, and economical solution to remarkably enhance the strength of graphite dies by employing the pre-stressed carbon fiber winding technology. An engineering application of a graphite die for hot pressing at 1273£¿K demonstrated the reliability and practicality: the original graphite die breaks under a punch pressure of 70£¿MPa and the carbon fiber wound graphite dies work well under a punch pressure up to 100£¿MPa. The finite element simulations illustrate that the 1-mm-thick layer of carbon fiber is able to reduce the maximum principal stress of the graphite die effectively from 130£¿MPa to 30£¿MPa. This is the first application of the pre-stressed carbon fiber winding technique to high-temperature components
