4.1.2 Hygrothermal and Transport results

If you collapse Moduli and expand everything else (by clicking the \includegraphics[width=14pt]{./Images/expand.png} sign), you get something like this:

$\alpha _1, \alpha _2$. Longitudinal and transverse coefficient of thermal expansion (CTE). Longitudinal means in the fiber direction. Transverse means perpendicular to the fiber direction. Please do not neglect these values because thermal stress/stresses is/are very important for composites.

$\beta _1, \beta _2$. Longitudinal and transverse coefficient of moisture expansion (CME).

$\sigma _1,\sigma _2$. Longitudinal and transverse electrical conductivity. In the electromagnetic literature, it is customary to call this property by $\sigma $, which conflicts with our use of the same Greek letter for stress, but electromagnetics is a specialty field, so there is no risk of misunderstanding.

$\sigma _3$. Electrical conductivity through-the-thickness (of the lamina). These are important values if you need to evaluate the impact of electromagnetic fields, impulse, and lightning strike on aircraft or similar situations.

$D_1,D_2,D_3$. Mass diffusivity coefficients. Used to calculate the permeability of your product to gas or fluid. Important if you are designing a tank or pressure vessel, etc.

$\kappa _1,\kappa _2,\kappa _3$. Thermal conductivity coefficients. Used to calculate the heat transfer, conduction, or insulation provided by your product. Important if you are estimating insulation, thermal barrier, thermal protection systems (TPS), etc. In the heat transfer literature, it is customary to call this property by $\kappa $, which conflicts with our use of the same Greek letter for curvature, but heat transfer is a specialty field, so there is no risk of misunderstanding.
