Semi-defibration of wood as pretreatment for wood flow forming -The effect of semi-defibration on penetrability of wood

摘要

Wood flow forming is a new method in which wood block is processed into product with three dimensional shape. The forming process includes the heating, pressing, and cooling in a mold. In this process, wood block is separated at around intercellular layer into smaller parts, and subsequently flown into the empty space in the mold. The separated parts are re-bonded to each other and then fixed. The flowability of wood and the physical properties of products, however, is required to be improved. One ofthe representative techniques to improve such properties is the impregnation of wood with a given resin. It is necessary to solve the isuue as to the irregular distribution of the resin in wood.
