A Method to Determine Moisture Profiles from Total Moisture Weight-Gain Data in Polymeric Composites

Abstract

This article presents a numerical approximation scheme, based upon the method of moments, to evaluate moisture distributions within a composite plate from data on total moisture weight-gain. Although it is assumed that the diffusion process remains linear, the scheme applies to moisture uptake data which depart from classical predictions. Two examples are provided to demonstrate the validity of the scheme.
