FIBROUS SHEET
A fibrous sheet for structure reinforcement comprising a sheet layer of reinforcing continuous filament bundles arranged parallelly spaced out from each other; said reinforcing continuous filaments having a tensile strength of at least 20 g/de, auxiliary covering yarns arranged on both sides of said sheet layer in such a manner that each of said covering yarns intersects respective reinforcing filament bundles while meandering along the longitudinal direction of said reinforcing filament bundles on at least one side of said sheet layer, and auxiliary chain-stitching yarns which interconnect the auxiliary covering yarns on one side of said sheet layer with the auxiliary covering yarns on the other side of said sheet layer through individual spaces among adjacent reinforcing filament bundles in a warp knitting structure.
