An abrasion-resistant composite sheet having a surface layer of pile-like fibers immobilized by resin. The surface layer has a thickness of 0.5-3 mm, a pile-like fiber concentration of 0.05 to 0.5 g/cm.sup.3, a resin containing depth of at least 0.5 mm and a density of at least 0.5 g/cm.sup.3. The p

An abrasion-resistant composite sheet having a surface layer of pile-like fibers immobilized by resin. The surface layer has a thickness of 0.5-3 mm, a pile-like fiber concentration of 0.05 to 0.5 g/cm.sup.3, a resin containing depth of at least 0.5 mm and a density of at least 0.5 g/cm.sup.3. The pile-like fibers can be derived from particular contracted stitchbonded, knit or woven fabrics or from conventional pile fabrics having specific characteristics.
