Mechanical characteristics were evaluated of wood-bamboo-based particleboard having the proportions of 100% wood and 0% bamboo, 75% wood and 25% bamboo, and 50% wood and 50% bamboo. This particleboard used Eucalyptus urophylla × grandis wood, Dendrocalamus asper bamboo, and castor oil-based polyurethane resin. Through destructive testing, the values of perpendicular tensile, static bending, modulus of elasticity, and screw pullout strength in the top and face surfaces were analyzed. For 0%, 25%, and 50% bamboo the values were 1.68 MPa, 1.37 MPa, and 1.4 MPa, respectively, for perpendicular tensile; 15.2 MPa, 17.6 MPa, and 18.5 MPa, respectively, for static bending; 2466 MPa, 2694 MPa, and 2922 MPa, respectively, for modulus of elasticity; 1256 MPa, 1922 MPa, and 1362 MPa, respectively, for screw pullout strength in top; and 1392 MPa, 1342 MPa, and 1414 MPa, respectively, for screw pullout strength in face. These results were superior to those presented by ABNT NBR 14810 (2013) and ANSI 208.1 (1999). After performing a Tukey test at 5%, the values for each treatment did not show a significant difference among them.

Four cross-laminated timber (CLT) panels with and without bamboo reinforcement were prepared and evaluated. The goal was to obtain better possibilities of using this lignocellulosic panel, based on their mechanical properties. Stiffness and strength of compression parallel to grain tests were conducted to simulate the utilization of this material as freestanding walls. Panels were produced based on Pinus elliottii wood species and glued with castor oil-based polyurethane resin. Half of these structural panels were also reinforced with strips of Dendrocalamus asper bamboo species, which were added on the outer layers. There was a significant increase in the parallel compression-to-grain in the configuration of the cross-laminated timber reinforced with bamboo in the longitudinal direction, which concentrates superior resistance.
