US 2026/0159440 A1 · GLASS FIBER AND METHOD FOR PRODUCING THE SAME

Abstract

A glass fiber and method for producing the same are provided. The method for producing the glass fiber includes a covering process, a mixing process, and a drawing process. The covering process is implemented by covering a plurality of silicon nitride powders onto a plurality of surfaces of a plurality of inorganic particles to form a plurality of modified inorganic particles. Based on a total weight of each of the modified inorganic particles being 100 wt %, a content of the silicon nitride powders is between 0.01 wt % and 5 wt %, and a content of the inorganic particles is between 95 wt % and 99.99 wt %. The mixing process is implemented by mixing the modified inorganic particles into a glass raw material. The drawing process is implemented by drawing the glass raw material having the modified inorganic particles mixed therein to form a glass fiber.
