A composite structural product is provided which comprises light weight core s made from processed kenaf, balsa or other cellulosic stalks (12, 14) bonded together. These may be conveniently manufactured into core blocks (10), and later sized and joined as the core members of a composite structure, e.g. laminates (30), fiberglass walls (38), or plastic encased products. The othe r members of the composite could include many different materials, from metals to woods to synthetic polymers such as thermoplastic and thermosetting resin s (37). In one form, the kenaf or balsa stalks are formed into small strips or grindings for use as a light core weight filler in molding processes.</SDOAB > |
