Mechanics and analysis of fabric composites and structures

This paper is devoted to the mechanics, modelling and analysis of fabric-reinforced composites and structural components. A theoretical and experimental characterisation of elastic properties of the textile composites is considered. Typical stress-strain diagrams for fibreglass fabric composites and composites reinforced with knitted fabrics loaded in tension at different angles are presented. The special case of the three-dimensional reinforcement structure of composite material, composed of spatially-oriented fabric layers is discussed and corresponding models considered. Manufacturing technology for such structures includes a three-dimensional lay-up process in which the specially designed fabric patterns are placed onto the mould or mandrel. The implementation of the material model is illustrated with results of the stress-strain analysis of thin-walled spatially reinforced structural components.
