Physical and Mechanical Properties of Qualea albiflora Wood Specie

The present project aimed to characterize the wood of the species Qualea Albiflora (Mandioqueira) in order to enable its use for structural purposes. The tests to obtain the physical and mechanical characteristics were carried out according to the Brazilian standard ABNT NBR 7190 (1997) allowing the classification of the species as wood suitable for use in heavy constructions. After the characterization it was verified with the aid of regression models (linear logarithmic exponential and geometric) that it is not possible to make use of the apparent density in the estimation of the other physical and mechanical characteristics obtaining a bad adjustment in all the cases (R²<50.00%) and the non-representativeness of the models adopted (P-Value> 0.05).
