QUALITY OF TROPICAL HARDWOOD FLOORS

This study aimed to determine the basic density of the wood and to simulate the performance of flooring produced with wood from five tropical species: Dipteryx odorata (Cumaru), Handroanthus spp. (Ipe), Hymenaea Courbaril (Jatoba), Astronium Lecointei (Muiracatiara), and Bowdichia virgilioides (SucupiraPreta). Falling steel sphere, static and dynamic friction, indentation caused by loads applied in small areas, rolling load, and abrasiveness impact tests were simulated. The results were subjected to analysis of variance and Tukey's test at 5% significance, and Pearson's correlation was performed between the basic density and the indexes of each flooring. The basic density of the wood flooring made from the evaluated species ranged from 0.735 to 0.958 g.cm(-3). D. odorata, Handroanthus spp. and H. courbaril woods were classified as heavy, while those of A. Lecointei and B. Virgilioides as moderately heavy. It was possible to indicate D. odorata, Handroanthus spp., H. courbaril, and B. Virgilioides flooring for environments with intense traffic where there is dragging or falling objects such as industries and companies. The A. Lecointei flooring can be used in residential environments with light traffic, where the loads exerted are low. There was a correlation between the basic wood density and the flooring use simulation tests.

Automated summary

This study aimed to determine the basic density of wood from five tropical species and simulate the performance of flooring made from them. The results showed a correlation between the basic wood density and the flooring use simulation tests. The study identified suitable flooring options for different environments based on the wood density and performance simulation results.
