description	FIELD: polymer materials. ^ SUBSTANCE: sheet porous collagen-containing material, suited to be used in footwear, furniture, and vehicle manufacture, comprises water-soluble plasticizer and particles of hydrophilic filler in the form of fibers with length-to-diameter ratio between 5 and 500. At least 50% of fibers are parallel to sheet sides with largest surface areas. This sheet is characterized by rupturing relative elongation when stretched in one direction in planes of the largest sides equal to 10-30%, modulus of compression elasticity for thickness equal to 50-300 kPa, and coefficient of thickness restoration after 70% compression for 5 h equal to 0.90-0.95 at 8-12% moisture. Also described is method of manufacturing such material including following operations: mixing hydrophilic fibers having length-to-diameter 5-500 with aqueous collagen solution and multifunctional cross-linking agent to form homogenous mass containing 1-20% fibers, 1-5% collagen, and 0.2-20% cross-linking agent; freezing liquid sheet and unfreezing it followed by pressing resulting porous sheet; softening with water-soluble plasticizer; second pressing; and drying. ^ EFFECT: enhanced damping ability of sheet and simplified manufacturing technology. ^ 8 cl, 2 tbl, 10 ex
