Feeder for glass fibers and method of producing

摘要

A method of fabricating a glass fiber forming feeder is provided comprising positioning a refractory metal core between oxygen impervious, precious metal layers to form a pre-laminate unit, said core having apertures extending therethrough; cold isostatically pressing said unit to move a portion of said layers into said apertures into intimate contact with substantially all of the core defining said apertures; and then hot isostatically pressing said unit to intimately bond said precious metal layers to said core including the portion core defining said apertures to form said laminate to prevent the oxidation of said core at elevated temperatures.
