Glass−Carbon Composite Hollow Fibers

Abstract

Glass−carbon composite hollow fibers were prepared by extruding a suspension of glass particles in an N-methylpyrrolidone solution of poly(ether sulfone). The fibers were gelled in water and pyrolyzed for 0.5−30 min in a furnace preheated to 1100−1200 °C. The resulting composite carbon−glass fibers had about 2.1 mm o.d. and 1.3 mm i.d. Scanning electron microscopy was used to examine fiber morphology, while the nitrogen permeance was about 7 × 10^(-5) mol/m^2·Pa·s, indicating pores of micron size. Compared to pure glass fibers, which are easily deformed at 900 °C, the composite fibers could withstand temperatures up to 1200 °C without suffering deformation.
