The dependency of composite strength under combined normal stress is experimentally determined as fiber content varies over the range 40 less than or equal to vf less than or equal to 75. Failure predictions of the tensor polynomial criterion agree well with experimental data in stress space. The maximum strain criterion predicts a physically inadmissible failure envelope in stress space due to the assumed linear constitutive law. In strain space the maximum strain criterion agrees favorably with experimental observation.
