Diffferent criteria have been proposed to predict the.failure of fibrous composite materials. Hashin had the indubitable merit of introducing the idea that the failure criteria associated to fibrous composite materials ought to be associated to the observed mechanisms of failure, although it was not exactly covered by his proposals .. In this paper the two Hashin proposals on failure of the matrix in compression are studied in the context of unidirectional composites. The emphasis is put in elucidating the reasonahility of the appearance of an out of plane allowable, the transversal shear strength, in the prediction of failure of the lamina under in plane loads, as happens in the second Hashin proposal. lt is concluded that even recognizing that the failure may involve out of plane mechanisms, this effect can be perfectly reflected by in plane variables. An additional incoherence of the dependence of the criterion with the transversal shear strength is finally shown.
