Paper Abstract

Dimensional stability is the time dependent strain response to mechanical thermal chemical or physical loads whether internal or externally applied. This paper presents recent work on moisture induced strains and viscoelastic behavior of polymer matrix composite materials. Topics covered include determination of lamina coefficients of moisture expansion (CME) or /11 and P22 and the microyield strength (MYS). It is shown that the creep recovery part of a MYS test can be a sensitive indicator of moisture level and/or matrix damage. 1.
