Phenol Resorcinol Formaldehyde is an adhesive commonly used in the fabrication of
glued laminated (glulam) timber beams. Although, it has been widely accepted for softwood
species, the verification of this type of adhesive for local timbers is not fully established. Four
glulam beams and four solid beams were tested in bending in the laboratory. Phenol Resorcinol
Formaldehyde was used as an adhesive for glulam beams. The strength of the glulam beam
structure was equivalent to solid beam structure. Phenol Resorcinol Formaldehyde was able to
provide sufficient bonding and strength for local timbers. The results indicated that the most
significant factor influencing the strength of solid beam and glulam beam structure was the density
of timber.
