Some experiments for the determination of elastic moduli of fabric composites are conducted in order to examine the theory proposed by the authors. Comparison of theory and experiments leads to a good agreements for 8 harness satin carbon/expoxy systems. In the case of plain weave composites, there is a great discrepancy between warping constrained and unconstrained theories. Experimental results fall these two theoretical curves. Clear dependency of elastic moduli on ply number is found for plain weave. A ratio of ply thickness to thread width is also a very important parameter by which elastic moduli of plain weave composites is strongly affected. In-plane shear modulus of fabric composites is mainly determined by fiber volume fraction which is likely to be decreased corresponding to small ng. Mechanical models for the theory is basically verified by this examination.
