Abstract
The invention relates to an in-line process for producing high-temperature stable glass. A sizing composition is advantageously used to reduce plasticizing between the resinous matrix and the glass fibers. The in-line process uses a melter or furnace apparatus, including a top charging and melting section and an intermediate flow regulator section having a baffle system improving the heat pattern across the glass flow, and a bushing having a tip plate for receiving molten glass from a furnace. The bushing has an enlarged size that allows drawing of a significantly increased number of glass fibers at one time. The fibers have essentially no catenary and may be wound to create a tightly wrapped package of glass fibers of uniform exterior diameter throughout their width. High-strength, high-silica fiber made according to the invention may be advantageously used in filament-winding, pultrusion and weaving processes.
