Abstract
A resonant piezoelectric oscillator method for measuring elastic moduli was applied to composite materials. The complete set of elastic compliances of a superconducting coil composite was determined semicontinuously between 4 and 300 K. Also, two moduli of a layered fiber-glass–epoxy composite were determined; this composite is essentially the matrix material of the coil composite. The Young’s moduli, shear moduli, Poisson ratios, and elastic stiffness coefficients are also reported. Results agree closely with elastic data obtained by conventional testing methods.This publication has 40 references indexed in Scilit:
