Abstract

Abstract: It has been confirmed in several other studies is that the effect of yarn geometry variations on composite properties is non-negligible. This work presented a parameterized and automated modelling method for generating 3D orthogonal woven composite RVE geometry including yarn geometry variations. In this method, an RVE was considered to be obtained by geometrically transforming several basic yarns containing some geometrical features. Yarn geometry variations are considered and in particular two special parameters are defined to adjust the binder yarn embedded modes and outer-warp transverse bending. The section and path geometry are described by several parametric splines, where common spline control points are defined to treat the geometric contact between the interwoven yarns. An actual 3D orthogonal woven preform was used to verified the validity of the proposed method. Finally, two sets of RVE models were established to study the effects of the binder embedded and outer-warp transverse bending on the material elasticity moduli.
