The decade of the 1970s was one of profound change for wood-based structural panel producers 1n the United States. Many new panel types were introduced, including structural particle board or flake board, water board, oriented strand board (OSB), and composite plywood. Together with these new products came various definitions of structural composite panels to identify and differentiate them. Gatslick and Bean (1977) defined structural composite products as any reconstituted wood product designed to meet specific physical and mechanical performance standards, or as a composite that can economically replace conventional lumber, plywood and laminate pro- ducts with load-bearing performance requirements.
