Abstract

The wood-base fiber panel materials are a part of the rapidly evolving technology based on converting lignocellulose to fiber and reconstituting the fiber into large sheets and panels. While some equipment and techniques used are the same as for producing paper, there are enough differences in techniques used and other requirements for manufacture that a separate treatment of the subject is warranted. This research note describes the various requirements for raw materials and equipment, describes various steps in manufacture, and presents summaries of important strength and physical properties of insulating board, medium-density building fiberboard, and hardboard.
