Molding method and molded body of plant-based material

摘要

In order to provide a method for molding a plant-based material for molding a relatively long plant-based material by a simple device and process into a three-dimensional shape having an arbitrary cross-section while maintaining the continuity of the cell tissue inherent to the plant-based material, the constituent tissue of a long plant-based material that is long in the fiber direction is subjected to compression/squeezing deformation continuously in the direction of the center of the material while extruding the material through an extrusion die having a predetermined extrusion ratio and die angle, whereby a long plant-based material having a higher density and strength is obtained.
