“…Each type of adhesive requires a specific range of moisture content of the wood, in order to promote an adequate adhesion between the pieces of laminated wood. The epoxy adhesive presents better adhesion to the wood with moisture content close to 12 % [17]. The satisfactory results for the mechanical properties can be explained by the good adhesion between adhesive and wood.…”

The aim of this study was to evaluate the properties of Hevea brasiliensis wood wastes for production structural pieces of glued laminated (glulam) timber. Three trees with age close to 25 years and diameter at breast height (DBH) higher than 500 mm were obtained. The basic density of the wood were quantified, as well as the stiffness and the strength in static bending, shear strength and parallel compression to grain and hygroscopic equilibrium moisture. The beams of glulam were evaluated according to the modulus of elasticity (MOE), modulus of rupture (MOR) and delamination. Due to the bending properties MOR (75.14 MPa) and MOE (8166.79 MPa), as well as the shear strength (12.29 MPa) obtained, was concluded by the suitability of the rubber wood for the production of glulam beams. The composite beams presented values of MOR (75.14 MPa) and MOE (8166.79 MPa) compatible with species traditionally used in the production of glulam beams. The adhesive bond quality was verified by the delamination test, presenting delamination of 4.95 %, indicating its use for internal and external environments.

“…It was found in another study [21] that an inadequate bond is formed between wood and epoxy resin and that in general the bond strength did not reach the strength of the timber used in the research. Well-regarded technical documentation on repairing glued laminated timber with epoxy adhesives cautions against their use without mechanical reinforcement [22].…”

“…A conclusion from an early research programme investigating commercial epoxy adhesives for timber applications was that starved joints were the principal cause for low bond quality [7]. In another early study which examined the bonding of wood with epoxy adhesive, it was reported that the bond strength formed in the joint failed to reach the strength of the timber and it was considered that an inadequate bond was formed [8]. Durability of the bond has been reported as a concern when no coupling agent has been applied to the wood surface [9][10][11].…”
