This paper presents the results of an experimental investigation of the effects of voids upon the hygral and mechanical properties of AS4/3502 graphite/epoxy. Simple uniaxial tension tests were employed to determine the effects of voids upon ply moduli E 11 , E 22 and G 12 , and the Poisson ratio ν 12 . The matrix dominated moduli E 22 and G 12 were found to depend significantly upon void content while little dependence was noted for the fiber dominated properties E 11 and ν 12 . Moisture conditioning experiments showed that both the rate and the equilibrium level of moisture sorption depend upon void content. In addition, non-Fickian diffusion anomalies were observed in high void content specimens while specimens with low void content displayed classical Fickian behavior.
