Abstract
Methods and compositions are described for producing high-performance materials. These materials utilize layers of stacked tapes wherein the tapes in any given layer are offset by between 0.1 degrees and 45 degrees from tapes of adjacent layers. At least three roughly parallel tapes are included within each layer of tapes, and the tapes have an aspect ratio of at least 20. The maximum thickness of a tape within a given layer is 5 mm. The resulting materials have significantly improved strength and/or toughness. The compositions can be used as stand-alone materials or combined with other materials to form tape-reinforced composites.
