Abstract
A composite board having a sorghum stalk material component and a binder component is disclosed together with a corresponding method of manufacture. To prepare the composite board, the sorghum stalk material is harvested, dried and refined into fibers. The fibers are then combined with a binder such as a thermosetting resin. The resin coated fibers are then arranged into a stack having several layers. Within each layer, the resin coated fibers are aligned along a predetermined layer axis. Next, the stack is thermocompressed in a press at a preselected temperature to compress the resin coated fibers to a preselected board thickness.
