Abstract
A method for the production of a composite consisting of cellulose fibers coated with a calcium phosphate compound consists essentially of phosphorylating the surface of cellulose fibers, immersing the surface-phosphorylated cellulose fibers in an aqueous solution containing calcium ions and hydroxyl ions, removing the cellulose fibers from the aqueous solution and subsequently immersing them in an aqueous solution containing calcium ions and phosphoric acid ions, and then removing the cellulose fibers from the aqueous solution. Also disclosed is a composite produced by the method.
