Study on the Effect of Finger-Joints on the Strengths of Laminations from Fiber-Managed Eucalyptus nitens

The performance characteristics of finger-joints as a jointing technique for Eucalyptus nitens is crucial their use in engineered wood products. This research evaluated the strength finger-jointed laminations made from fiber-managed E. nitens. A total 237 specimens with (117 pieces) and without (120 were sectioned tested by bending, tensile, shear, bearing tests. Bending tensile tests paired to identify any correlations. mean value bending 92.1 MPa 79.6 MPa, respectively. presence reduced values. Joint efficiencies are 0.73 0.62, distributions similar samples finger-joints. For finger-joints, was significantly lower than strength. Shear test results show that short-span inefficient obtaining shear boards. Meanwhile, finger-joint efficiency 0.86. prediction models lamination’s established non-destructive properties predictors. highly correlated modulus elasticity value, while density. study obtained promising on boards suggesting they could be suitable structural purposes.
