Title:
COMPOSITE MOLDED BODY, METHOD OF MANUFACTURING THE SAME, AND FIBER COMPOSITION
Document Type and Number:
Japanese Patent JP2021165454
Kind Code:
A
Abstract:
To provide a composite molded body, and a method of manufacturing the same, which are capable of forming a member in which cellulose fine fibers are uniformly dispersed while having a large thickness dimension, and a fiber composite.SOLUTION: There is provided a composite molded body containing cellulose fine fibers and an organic filler, in which: an average fiber diameter of the cellulose fine fibers is 5 nm or more and 2 μm or less; a content of the cellulose fine fibers in the composite molded body is 3 mass% or more and 90 mass% or less; a basis weight of the composite molded body is 50 g/m2 or more and 1000 g/m2 or less; an average air permeation resistance of the composite molded product is 0.5 seconds/100 mL or more and 100,000 seconds/100 mL or less; a coefficient of variation of the air permeability resistance, which is a value obtained by dividing a standard deviation of the air permeability resistance of the composite molded body by the average air permeability resistance, is 0.5 or less; an average minor axis diameter of the organic filler is 0.1 μm or more and 100 μm or less; and a thickness of the composite molded body is 100 μm or more and 10000 μm or less.SELECTED DRAWING: None
