Two-point bending and tensile strength tests on aged fibers with different glass and coating compositions

摘要

Abstract: Several different optical fibers have been aged in 21, 60 and 85$DGR@C water under essentially zero stress conditions. Included are fibers with both synthetic and natural quartz glass surfaces and also different coating materials. During aging samples have been taken out and both two-point bending and tensile strength tests have been made. Results indicate that there is no clear difference between synthetic and natural glass strength after aging. On the other hand the coating material has a significant effect on the strength of similarly prepared glass fibers.!7
