Disposing of Silica Fiber' Surface

摘要

Silica fibers are widely used in superhigh velocity radome and antenna windows. The methods of eliminating the agents on the surface silica fibers were sdudied in this paper. SEM was engaged in studying the effects of silica fibers disposed by different methods, and the tensile strength of disposed silica fbers was compared with the originals. The results showed that the heat treatment in the high temperature was a useful means to eliminate the agent on the surface of silica fiber, but there was great thermal damage for silica fibers, and the tensile strenth decreased significantly. The combination of volvent treatment and heat tratment could eliminate the agent on tht surface of silica fibers completely, and the tensile strength retained more, which was a good means to eliminate the agents on the surface of silica fiber.
