Improvement in Fiber Testing of High‐Modulus Single‐Filament Materials

Abstract

The standard procedure for determining the tensile strength and Young's modulus of single‐filament ceramic fibers (outlined in ASTM test method D‐3379‐75) was modified for accurate determination of Young's modulus, especially for fibers with larger diameters. An improved plotting method to determine the system compliance factor was developed; this method allows for variations in fiber diameter and produces more accurate Young's moduli.
