Resumen
The aim of this study was to evaluate the physical and mechanical properties of four thermomechanically treated tropical woods for the production of hardwood flooring. The following species were selected: cedrinho (Erisma uncinatum Warm.), angelim (Hymenolobium sp.), tachi preto (Tachigali myrmecophila Ducke) and mandioqueira (Qualea paraensis Ducke). Samples measuring 100 mm x 300 mm were thermomechanically treated in a hydraulic press at 145°C. Physical, mechanical and colorimetric properties were assessed. Thermomechanical treatment was efficient to decrease the moisture content and surface wettability of woods. Apparent density of angelim and mandioqueira woods increased significantly. The same woods presented the highest compression ratio. Wood color of all species became darker, mainly due to the reduction of lightness. Average values of mechanical properties increased in comparison to average values of reference.
