Abstract (en)

[origin: WO9635578A1] A composite sheet having a surface layer (17) of resin-impregnated pile-like vertical fibers (10) provides the sheet with unusually high resistance to abrasive wear. The surface layer (17) has a combination of characteristics that includes an effective pile-fiber concentration of 0.1 to 0.5 g/cm<3>, an over-all density of at least 0.4 g/cm<3>, a resin content of 25 to 90 weight % and a pile parameter of at least 0.3 grams/cm<3>. Preferably, the pile-like fibers (10) contained within the surface layer (17) are derived from particular contracted knit fabrics or contracted two-bar stitchbonded fabrics (20).
