文摘

This paper provides the Young¡¯s modulus profile across anisotropic nonhomogeneous polymeric fibre using an accurate transverse interferometric method. A mathematical model based on optical and tensile concepts is presented to calculate the mechanical parameter profiles of fibres. The proposed model with the aid of Mach-Zehnder interferometer combined with an automated drawing device are used to determine the Young¡¯s modulus profiles for three drawn polypropylene (PP) fibres (virgin, recycled and virgin recycled 50/50). The obtained microinterferograms are analyzed automatically using fringe processor programme to determine the phase distribution.
