Due to the inherent symmetry of as-produced textile fabrics, woven composite plates are orthotropic. Their stiffness can be represented by engineering constants Young s modules shear modules Gy and Poisson coefficients py, ij= 1,...,3. If the reinforcement is deformed during production of the composite, or if the preform is net shaped, or for some knitted performs, then the assumption of orthotropy does not necessarily apply and the full stiffness matrix has to be introduced.

Modelling of textile and, in particular, woven composites is an established, mature field, which has passed a long way of increasing model complexity from early models referring to the classical laminate theory, adapted to account for knockdown factors due to fibre crimp, to advanced models of today, based on meso-level (woven unit cell) FE analysis. Several specialised commercial and open-source numerical tools for simulation of textile unit cells are now available. [Pg.46]

Predictions of 2D and 3D woven composite stiffness properties have the adequacy level necessary for their use in practical design optimisations. Meso-level predictors for composite stiffness are integrated with macro-level FE tools for structural analysis. [Pg.46]
