 The present work identifies the influence of sysil-fiber waviness on elastic properties such as longitudinal modulus, transverse modulus, shear modulus, major and minor Poisson's ratio through experiments and numerical simulations. The study uses different wavy patterns of half-sine waviness, full-sine waviness, and mixed waviness to determine the effect of waviness ratio, a lambda, on elastic properties using micromechanics approach. Additionally, the influence of mixed waviness of sysil-fiber on elastic properties is identified through experimental as well as micro- and macromechanics principles. The results show that the waviness of the fiber has a significant effect on the composite modulus in all directions. This article was authored by P. Funny Prosanthi, K. Sivaji Babu, M. S.
