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 n<SUB>g</SUB>. Mechanical models for the theory is basically verified by this examination.
