Optimum Design of Substitute Lumbers Molded from Fiber Waste

The effects of length and diameter of binder fiber on the binding condition and also the bending properties of molded substitute lumber were discussed in this paper to construct the optimum design of the material processing of the substitute lumber from the fiber wastes. The PP fiber was used as a binder material and the length and the diameter were varied in the experiments. The melting behavior of PP fiber was observed minutely during the compression molding process. As a result, it is concluded that the higher strength can be obtained for the case where the fiber wastes are coated by PP resin along the fiber axis
