Metal-coated glass fiber, metal-coated glass fiber bundle, method for producing metal-coated glass fiber, and method for producing metal-coated glass fiber bundle

摘要

The present invention provides a method for efficiently providing a metal-coated glass fiber and a metal-coated glass fiber bundle in which the thickness of the coated metal is uniform in the circumferential direction of the glass fiber, and a metal suitable for a glass filler. It is an object to provide a coated glass fiber bundle. A method of manufacturing a metal-coated glass fiber according to the present invention includes a dome-shaped glass fiber drawn out from a bushing nozzle of a glass melting furnace and exuding from a hole of a metal melting furnace for forming a metal coating layer. Alternatively, in a method for producing a metal-coated glass fiber to be brought into contact with a substantially spherical metal melt, two holes are formed in the wall surface of a metal melting furnace, and two droplets of the metal melt are each Contacting or exuding so as to overlap, so that the glass fiber traveling downward is brought into contact with both of the two droplets through the depression formed by the two droplets to coat the glass fiber with metal.
