Abstract
This invention discloses a high-strength, high-temperature-resistant carbon fiber reinforced 3D printing consumable and its preparation method, comprising a continuous carbon fiber bundle and a sheath layer, wherein the sheath layer comprises a blend matrix of chopped carbon fibers and a high-temperature resistant polymer; through the core-shell multi-scale structure of continuous fiber + chopped fiber, the axial ultra-high strength and multi-directional reinforcement and high resistance to interlaminar cracking are unified, breaking through the limitations of a single reinforcement form.
