Steam injection pressing : large panel fabrication with southern hardwoods

Abstract

Large 4 by 8 ft (1.22 by 2.44 m) panels were made using a steam injection method of pressing. Homogenously constructed flakeboards were fabricated from southern red oak, sweet gum, and a mixture of the two species using both isocyanate and phenolic resins. Isocyanate was especially suited to the process and 1-1/2 in. (38 mm) thick panels were pressed in less than 150 seconds. Phenolics on the other hand were susceptible to dilutions by steaming and required higher temperature to cure.
