Abstract
Official abstract text for this publication.
The invention concerns multiaxial fabrics comprising a first layer comprising a plurality of first yarns being substantially parallel in a first direction; a second layer comprising a plurality of second yarns being substantially parallel in a second direction and skew of off-set with respect to the first yarns; a third yarn layer comprising a plurality of third yarns being substantially parallel in a third direction and skew of off-set with respect to the first yarns and second yarns; a fourth yarn layer comprising a plurality of fourth yarns being substantially parallel in a fourth direction and skew of off-set with respect to the first, second and third yarns; at least one fiber network layer; and a transverse yarn interlaced transversely within the multiaxial fabric where each layer may be arranged in any sequential order and optionally coated with a high viscosity polymer that has a glass transition temperature Tg in the range of about −40 to about 0° C., and a zero shear melt viscosity of about 2×10 6 to about 10 13 poise at 20° C.
