Elastic constants

orthotropic

Physical, thermal and electrical

at 20 °C

Strength

a band applies up to and including its upper limit

Notes

Plane-stress (lamina) data: E₃, ν₁₃, ν₂₃, G₁₃ and G₂₃ are not given, so a 3D stiffness matrix is not formed. For a transversely isotropic lamina E₃ = E₂, G₁₃ = G₁₂ and ν₁₃ = ν₁₂; G₂₃ or ν₂₃ must come from elsewhere.
Y_c is left out: the copies checked give 25 and 53 MPa.
