Fiberboard Composites from Wood-fiber Bonded with Renewable Wood Resin

The brief report presented here deals with the feasibility of using renewable wood resin, in a mixture with urea-formaldehyde (UF) resin, as a binder in the manufacture of composite fiberboard. To make the fiberboards more economical and performance-driven, the UF resin is partially replaced by wood resin and the properties of the composites measured. The results indicate a satisfactory mechanical performance of the wood resin substituted fiberboard as allocated by the ANSI AHA standard. Resin curing conditions are optimized to obtain the desired performance of the composites.
