Claim:
1. A composite material comprising: a plurality of filament bands wound to define a composite sheet, wherein the individual bands are impregnated with a resin that is solid or semi-solid at ambient temperatures and becomes a viscous liquid to impregnate the filament bands when heated, the composite material having a plurality of layers of substantially parallel filament bands with an n number of first pairs of filament bands wherein the filament bands in each first pair have a same width w, are parallel to each other and are spaced apart from each other by a distance nw, and an N number of second pairs of filament bands, wherein the filament bands in each second pair have a same width W, are parallel to each other and are spaced apart from each other by a distance NW, wherein the first pairs of filament bands are parallel to each other and are oriented at a same angle α transverse to the second pairs of filament bands, and wherein each pair of filament bands is sequentially positioned for the composite sheet in numerical order, with n before N, wherein alternating layers have intersecting orientations with adjacent layers, such that the filament bands form a sheet of composite material.
