A low cost process of making composite products from sugar containing lignocellulosic materials, such as sugarcane bagasse and stalks of sorghum, corn, sunflower, flax, and the like, utilizing the residual sugars as bonding and strengthening agent. Comminuted sugar containing lignocellulosic material wholly composed of or partially in combination with other lignocellulosic materials, in the absence of adhesive binders or bonding agents. is molded at a temperature of at least 180 DEG C and a pressure and for a time sufficient to compound the material into a composite product. The free sugars in lignocellulosic materials act as a thermosetting adhesive binder, and provide both bonding and strengthening effect. The composite thus products possess great strength and excellent dimensional stability. These results are obtained to the greatest extent when the lignocellulosic materials contain higher proportion of sugars. |
