Summary

A new method is presented suitable for determining fiber diameters along the gauge length before conducting single fiber tests. This measurement is important to evaluate mechanical properties such as Young's modulus, strength and time-dependent failure. Diameter distributions were measured for Nextel 720 (3M) alumino-silicate ceramic fibers before the tensile tests. It was found that diameter distribution pattern along each fiber was different nonsystematically from other fibers. Reliability of Young's modulus was strongly affected by the representative diameter used for the stress determination.
