植物繊維強化樹脂組成物の製造方法

Japanese Patent JP7347739

B2

To provide a method for producing a vegetable fiber-reinforced resin composition, which improves mechanical properties by a method other than that using an additive.SOLUTION: A method for producing a vegetable fiber-reinforced resin composition includes a step of kneading a mixture that contains a resin and a vegetable fiber, by using a twin screw extruder including a region that meets formula (1): L1/D=A and formula (2): N≥8A. In the formulae (1) and (2), L1 is a length of the region; D is a screw diameter of the twin screw extruder; N is the number of kneading disks per shaft, included in the region; and A is the number of 5 or more.SELECTED DRAWING: None
