Composte Laminate Cross Section

These properties are expressed as integrals based on the cross section geometry on the warping functions for torsion shear bending and shear warping and on the individual stiffness of the laminates constituting the cross section.

Composte laminate cross section.

Due to this fact microscopic characterisation of composite laminates has an inherent section bias where one cross section is not necessarily an accurate representation of the complete sample.
