Dipteryx odorata;Pometia spp.;Quercus spp.;physical properties;mechanical properties

Three kinds of solid wood floorings made of Dipteryx odorata,Pometia spp.and Quercus spp.,were studied on their physical and mechanical properties by using the conventional measuring method.The results show that Dipteryx odorata recorded the least shrinkage rate and the biggest density,resistance to bending,MOE,compression strength parallel to grain,compression strength perpendicular to grain and impact ductility in the three species.Its quality belongs to the highest grade.The tangential direction shrinkage rate and impact ductility of Pometia spp.are less than those of Quercus spp.The other physical and mechanical properties of Pometia spp.are bigger than those of Quercus spp.Its quality belongs to high grade,except for its tangential direction shrink-age and impact ductility which are bigger than those of Pometia spp.The others physical and mechanical proper-ties of Quercus spp.are the least in the three kinds of flooring.Its quality belongs to mid-grade or high-grade.The results have practical guiding significance for production and usage of these solid wood flooring.
