Abstract

ABSTRACT 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. (Ipê), Hymenaea Courbaril (Jatobá), Astronium Lecointei (Muiracatiara), and Bowdichia virgilioides (Sucupira-Preta). 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.

热带硬木地板的质量

摘要:本研究旨在确定木材的基本密度，并模拟用五种热带物种木材制成的地板的性能:双翅鸟(Cumaru)、Handroanthus spp. (Ipê)、黄膜鸟(jatobil)、天竺葵(Muiracatiara)和维吉里亚(Sucupira-Preta)。模拟了钢球坠落、静、动摩擦、小面积载荷压痕、滚动载荷、磨耗冲击等试验。结果进行方差分析和5%显著性的Tukey检验，各楼层基本密度与各项指标进行Pearson相关分析。用评价树种制成的木地板的基本密度为0.735 ~ 0.958 g.cm-3。气味木、手花木和小檗属重木，松木和野松木属中重木。在工业和公司等交通拥挤、有拖拽或坠落物体的环境中，可以指出d.o odorata、Handroanthus spp、h.b urbaril和b.f ililioides地板。A. Lecointei地板可用于交通较少的住宅环境，在那里施加的载荷较低。基本木材密度与地板使用模拟测试之间存在相关性。
