Fabrication of ballistic resistant fibrous composites having improved ballistic resistance properties. More particularly, ballistic resistant fibrous composites having high interlaminar lap shear strength between component fiber plies or fiber layers, which correlates to low composite backface signature. The high lap shear strength, low backface signature composites are useful for the production of hard armor articles, including helmet armor.
