A Study of a Test Method for the Coefficient of Moisture Expansion of Composite Materials

A test method for determining the coefficient of moisture expansion( CME) of composite materials was proposed in this paper. Some factors that would influence the determina- tion of CME of composite materials were discussed. Experimental procedures were performed on the studies of moisture expansion of composites T30 0 /32 31. The results showed that the method presented here can be u sed for the determining of CME of composite materials.
