The Influence of Transverse Moduli on Through-Thickness Hygrothermal Expansion Coefficients in Symmetrical Composite Laminates

摘要

In this article, the effect of transverse moduli of the lamina on the through-thickness hygrothermal expansion coefficients of the [+-30°/+-15°]_(2s), [+-30°/+-45°]_(2s), and [+-30°/+-75°]_(2s) symmetrical composite laminates is presented. Based on the hygrothermal-elastic lamination theory, a dimensionless analysis has been used to study the influence of the various transverse elastic moduli E_2 and E_3 of a lamina on the through-thickness hygrothermal expansion coefficients in the symmetrical composite laminates.
