Abstract
A novel experimental method is developed to improve the sensitivity in measuring the hygric properties of a composite material. The technique is based on measuring the curvature of an unbalanced laminate introduced by the unbalanced interlaminar resultant forces. A theoretical foundation is established for evaluating the coefficients of moisture expansion (in the longitudinal and transverse directions) and the stress-free temperature from a single set of measurements. The measurement scheme is validated with a set of experiments using two antisymmetric cross-ply laminates [O2/9O2] and [O5/9O5]. The experimental results agree with the measurements reported elsewhere. This study reveals that the sensitivity of the technique is greater than that of traditional techniques.
