Good day everyone, as mentioned in the title, I would like to ask about the way to determine the tensile properties of each individual layer in a polymeric bilayer film via uniaxial tensile test. My samples are polymeric film coated with a layer of adhesive so it is impossible to measure the tensile properties of the adhesive itself. I need to know the influence of adhesive on overall tensile properties and interaction between adhesive and the polymeric film. Is it possible to obtain by calculation or any well-established formula to use? I would like to get the young modulus, tensile strength, yield strength, and breaking load of each layer. Thank you so much for spending your time on my question, your kindness is much appreciated.
