Cellulose fiber-containing molded article, and method for manufacturing same

Abstract

The present invention relates to the provision of: a cellulose fiber-containing molded article having excellent flexural modulus and Charpy impact strength; and a method for manufacturing the cellulose fiber-containing molded article. The cellulose fiber-containing molded article according to the present invention comprises cellulose fibers, a resin A, and a fatty acid metal salt, in which the fatty acid metal salt is a metal salt of a saturated or unsaturated fatty acid having 12 to 24 carbon atoms inclusive, the content of the cellulose fibers in the molded article is 15% by mass to 70% by mass inclusive, the content of the fatty acid metal salt is 0.1% by mass to 10% by mass inclusive, and formula (i) or (ii) is satisfied wherein X (GPa) represents a flexural modulus of the molded article and Y (kJ/m2) represents a Charpy impact strength at a thickness of 4 mm. 1 .8 ≤ X ≤ 3.5 and ⁢ 100 ≥ Y ≥ 3 ⁢ 8 - 8 ⁢ X ( i ) 3.5 ≤ X ≤ 10 ⁢ and ⁢ 100 ≥ Y ≥ 1 ⁢ 0 ( ii )
