The Effect of Moisture on Carbon Fiber Reinforced Composites. IV. Prediction of Changes in the Elastic Behavior.

Abstract

The changes in the elastic behavior of composites due to the reversible moisture absorption can be predicted when the matrix properties (E sub m and Nu sub m) have been determined as a function of temperature and moisture concentration. The composite is analyzed in terms of artificial delta-layers, analogous to laminated plate theory. If in addition the diffusion coefficient of moisture for the composite is known as a function of temperature one can predict the elastic behavior for any 'reasonable' environment as a function of time.
