Compressed fiber structural material and method for producing the same

Abstract

Provided is a method for easily producing a lamellar compressed fiber structural material which has mechanical characteristics close to those of in vivo bone and which is capable of easily increasing osteoblast even when a difference in strength exists. In order to solve the issues, the method for producing compressed fiber structural material 1, includes: a step of preparing biocompatible fiber 14 having an average diameter of 5 μm-50 μm and an aspect ratio of 20-500; and a step of molding compressed fiber structural material 1 by cold pressing/shearing biocompatible fiber 14, compressed fiber structural material 1 having an average pore diameter that is in the range of 60 μm-100 μm inclusive and a void fraction that is in the range of 25%-50% inclusive, both obtained by measurement in accordance with the mercury penetration method. Further, it is preferable for the cold pressing/shearing is performed by controlling a compressive pressure in the range of 200 MPa-2000 MPa, a shearing stroke length in the range of 0.2 mm-5 mm and a shearing velocity in the range of 0.5 mm/min-5 mm/min.
