Claim:
1. An integral material sheet with interconnected fibers comprising at least two integral monolayers, wherein at least one integral monolayer of the integral material sheet is free of bonding agent and has a thickness of less than 100 μm, and wherein the at least one integral monolayer comprises a plurality of drawn unidirectional polymer fibers having a strength of greater than 1.2 GPa, and wherein at least 80 wt. % of adjacent fibers within the at least one monolayer are mechanically fused together along at least 30% of fiber length through mechanical interlocking thereby forming an integral material sheet with interconnected fibers, and wherein the fibers are monofilaments or filaments spread from a multifilament yarn, and wherein the at least one monolayer has a maximum thickness of no more than 3 times a thickness of an individual fiber.
