Abstract

A method was developed for measuring the longitudinal shear modulus of uniform diameter single fibers. A length of the fiber with a weight attached at one end and suspended at the other end was used as a torsional pendulum. The longitudinal shear modulus of the fiber was expressed as a function of the suspended mass and its geometry, the length and diameter of the fiber, and the frequency of oscillation. Tests were conducted on five different types of fibers, graphite (IM6, Hercules), silicon carbide (Nicalon), K-glass, G-glass and aramid (Kevlar 49). Results are in good agreement with calculated values in the case of isotropic fibers. In the case of anisotropic fibers, such as graphite and aramid, no other experimental results were available for comparison.
