They measured the variation of the X-ray d-spacings of the sharp equatorial reflections for an at-PAN fiber and determined the cross-sectional area of a chain as a function of the applied stress. By assuming that there was no volume change (i.e., Poisson's ratio μ = 0.5) as the sample was strained, they estimated the strain along the chain axis of a crystal. Combining the stresses imposed on the fiber and the corresponding crystal strains, they constructed a stress/strain curve for an at-PAN crystal which gave an initial modulus value of 28 GPa along the chain axis.
