A new and improved structural material comprising an interpenetrating plastic and substrate network material composite including two phases, a first phase comprising a substrate of paper or paper-like material or other fibrous or absorbent material defining a fibrous network phase, and a second phase comprising a polymerized plastic material penetrating and intimately contacting the structure of the paper or other fibrous or absorbent material filling the voids and interstices between the fibers of the paper material and hardened to a desired condition of rigidity. The composite is formed by saturation and in situ polymerization from a solvolysis system. The composite material is further incorporated in a monolithic laminar structure by application of layers of the solvolysis adjusted for sufficient agglomerating and aggregative characteristics to form plastic weldments or fillets at intersections of the substrate portions. The structural system is characterized by monolithic interpolymerization between the layers. The invention is applied to pallets, platforms, and other load bearing applications.

A new and improved monolithic structural material comprising: an interpenetrating substrate and plastic material composite comprising first and second phases, said composite characterized by intimate physical and chemical bonding between the phases; said first phase comprising a substrate of absorbent fiber-like material forming a continuous phase fibrous network filler; said second phase comprising a polymerized plastic material extending thoughout and filling the voids and interstices of the fibrous network of the fiber-like material first phase, said second phase derived by in situ polymerization from a solvolysis system including at least a dissolved starting polymer substance and solvent in which the solvent reacts with the dissolved substance, said solvolysis system adapted for saturating and penetrating rather than merely coating the interstices and voids of the fiber-like material first phase, and for reacting and polymerizing throughout the fibrous network of the first phase; and at least one laminate coating of an agglomerating plastic material adherent and chemically bonding to the surface of said plastic material and substrate composite, said at least one laminate coating derived by in situ polymerization from a similar solvolysis system adjusted to have agglomerative characteristics for coating rather than saturating, said adjusted solvolysis system adapted to liquify the outer surface of the composite for chemical bonding and interpolymerization at the interface between the coating and the composite whereby said composite and at least one coating form a monolithic structural material.
