Reinforced wood structural member using cellulose bond line interface material. (Patents).
A reinforcement panel with a cellulose surface material improves
adhesion of the panel to one or more wood segments in wood structural
members such as laminated beams, wood I-beams, and trusses to provide a
cellulose material-to-wood segment interface that withstands high shear
stresses. The reinforcement panel is comprised of a purality of
reinforcement fibers that are preferably arranged parallel to one
another and aligned with the longitudinal direction of the panel, and
accordingly the wood structure. The fibers are maintained in position by
a resin encasement that completely encloses the fibers. A cellulose
surface material is impregnated with a polyester resin and adhesively
connected to a first side of the panel. The first side of the panel is
adhesively affixed to the wood structure at an area of high stress such
that the surface material is sandwiched between the resin encasement of
the panel and the wood structure. Thus, the panel provides improved
adhesion. The polyester resin provides dimensional stability and
resistance to moisture degradation.
