Abstract
This article addresses the finite-element (FE) analysis of a local fibre placement in a stitched fibrous mat. The term “structural” presumes here that the stitching yarn is relatively thick (contrary to a non-structural NCF kniting) and its fibre stiffness is much higher than the matrix stiffness (pure matrix filling so called “openings” — resin-rich zones — around the stitching sites). Simplest 2D FE models are developed; typical carbon-fibre mat, carbon yarn, and epoxy resin properties are used in calculation examples. The results show important influence of the local fibre distribution (caused by the yarn cross-sectional shape, in-plane opening shape, fibre re-orientation around openings, etc.) on the stress-strain fields and homogenized stiffness.
