1. A biaxially-stretchable barrier laminate fabric composite material comprising:
a biaxially-stretchable substrate fabric having a relaxed state and a biaxially-stretched state, wherein dimensions of the biaxially-stretchable substrate fabric are greater in the biaxially-stretched state than in the relaxed state, the biaxially-stretchable substrate fabric having first and second surfaces, the first and second surfaces being planar in the relaxed state and in the biaxially-stretched state;
a barrier film selectively attached to the biaxially-stretchable substrate fabric at a plurality of individual bond points, the barrier film having unbonded regions between the bond points,
wherein the biaxially stretchable barrier laminate fabric is configured such that:
when the biaxially-stretchable substrate fabric is in the relaxed state, the barrier film is in a randomly folded state in which random folds are formed in the unbonded regions of the barrier film, the random folds oriented with respect to a machine direction, a cross direction, and an orthogonal direction, wherein the machine direction, the cross direction and the orthogonal direction are mutually orthogonal to one another, and
when the biaxially-stretchable substrate fabric is in the biaxially-stretched state, the barrier film is in a flattened state in which the random folds are partially or fully unfolded.
