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.
