The composite is reeled up layer-by-layer, and each layer unidirectional. It is even simpler than wattled fabric

You don't have to use the simplistic rules of mixtures which have to rely on a host of assumptions. You can use TexGen4SC to obtain complete set of thermoelstic properties for any woven microstructures. The code can be freely launched in the cloud at https://cdmhub.org/resources/texgen4sc.

Dear Prof Yu,

There are various types weaving pattern available.

So, What if the fabric is in twill weave pattern, can we still calculate the mechanical properties of the composite materials?

Thank you.
