PROBLEM TO BE SOLVED: To provide: a composite material of a phenolic resin and a vegetable fiber defibrated product that can exhibit a high elastic modulus even when the cellulose component content is reduced; a formed body thereof; and a production method therefor.SOLUTION: Provided is a composite material of a vegetable fiber defibrated product and a phenolic resin, and a formed body 1 thereof; the vegetable fiber defibrated product contains a cellulose component and a lignin component; the content of cellulose component in the composite material is 15 mass% to 30 mass%; in producing the composite material, first, a resin solution obtained by dissolving a phenolic resin into a solvent is impregnated into a porous body composed of a vegetable fiber defibrated product; then, the solvent in the porous body is evaporated; and furthermore, in the production of the formed body 1, the forming is carried out at temperatures above the hardening temperature of the phenolic resin.SELECTED DRAWING: Figure 1 |
