Basic geometrical and material parameters are identified to characterize the structure of hybrid fabrics. Analysis of the elastic behavior is made based upon a mosaic model and the fabric composite can be regarded as an assemblage of assymetrical crossply laminates. Upper and lower bounds of elastic properties have been obtained and the results compare very favorably with experiments. The influence of fabric parameters on the elastic behavior has been demonstrated especially for the bending-stretching coupling effect. Essential considerations for fabric design also have been discussed.
