    Department of Forest Service Hardwoods: A Rev Southern Forest Experiment Station New Orleans, Louisiana General Technical Report SO-71 Terry Sellers, Jr., James R. McSween, and William T. Nearn Over a period of years, increasing demand for softwoods in the Eastern United States has led to an increase in the growth of hardwoods on cut-over softwood sites. tinfortunately these hardwood trees are often of a size and shape unsuitable for the production of high-grade lumber and veneer. They do. however. represent a viable. economic source of raw material for plywood, fiberboard, particleboard. and oriented strandboard lor flakeboards), all products that require the successful use of adhesives in their manufacture. The current status of gluing eastern hardwoods is reviewed in this report, with emphasis on hardwoods growing on southern pine sites. The subjects covered include adhesives, wood and wood-surface properties and their interactions with the adhesive, and the quality of the bonds produced when these hardwoods are used in the manufacture of end joints, laminates, plywood, and other composite panels. A variety of adhesives are available that equal or exceed the strength of the hardwoods being bonded. The choice of a particular adhesive is dictated in large measure by the adhesive price and the end-use criteria for the finished product. In discussing the gluing of eastern hardwoods, the approach taken is that the fundamentals that determine the quality of an adhesive bond should remain the same whether the substrate is a softwood or a low-, medium-, or high-density hardwood. To illustrate the differences encountered in gluing the various hardwood species and the best approach for dealing with them in terms of bonding fundamentals, in this report we will concex~trateon: The quality and character of the surface as aflected by wood structure.

  • AN OVERVIEW of STRUCTURAL PANELS and STRUCTURAL COMPOSITE PRODUCTS by M
    AN OVERVIEW OF STRUCTURAL PANELS AND STRUCTURAL COMPOSITE PRODUCTS By M. R. O'Halloran1 and J.A. Youngquist2 ABSTRACT Plywood has been the principal structural panel for construc­ tion since the late 1940's. Today, structural panels are evolving into products such as composite panels, oriented strand board, waferboard and structural particleboard. While plywood will be the mainstay of production for some time, newer production facilities tend to be of other product types. Performance standards provide an opportunity to evaluate all of these product types under a comnon set of requirements. Research efforts to characterize these products is under way by the American Plywood Association in an effort to expend markets for panel products. Structural lumber substitutes and configurations of these products in beams have significant potential in future markets. INTRODUCTION The objective of this paper is to review the status of struc­ tural panel products and to identify in a general way the technical state of the art. Other structural composites manufactured with the technology similar to that of structural panels will also be briefly considered. Research efforts covering manufacturing technology have been omitted. This paper sets the stage for discussions which took place at the workshop on Structural Wood Research which was held in Milwaukee, Wisconsin in October, 1983. STRUCTURAL PANELS The structural wood panel products industry's primary market is the light- frame construction industry. For the past three decades it has supplied panel products to suppliers and contractors for on- site assembly of residential and commercial structures. The wood panels are long lived, durable goods which are commodities manufac­ tured and distributed in standard sizes and grades.
