Inter laminar allowable shear stress

I am modelling a helicopter blade, with a leading edge mass ballast.
I am not sure how to get a standard value for the inter laminar allowable shear stress value for unidirectional carbon fibre.

Additionally, how would i model the allowable shear between the metallic mass ballast and the carbon fibre ontop of it?

 

Kind Regards,

Mohamed

    Can you elaborate your question?

     

    Do you want to determine inter laminar shear stress?

    Hello,

     

    Yes i want to determine inter-laminar shear stress.

     

    I also want to know what allowable values for this shear stress would be, for example for carbon fiber with epoxy.
