Abstract

Indian cedar (Acrocarpus fraxinifolius) is a wood species that occurs naturally in India, Myanmar (Burma) and Bangladesh, and has a high commercial value, with characteristics like mahogany and native cedars. The planting of Indian cedar has been undertaken in Brazil, but there is little information available regarding the characterization of the species. Therefore, considering its timber potential and its possibility of development in the country, the present work aimed to evaluate the physical, chemical, and mechanical properties of 9-year-old Indian cedar wood, planted in the southern region of Brazil. A low specific mass (502 kg/m3), low average dimensional stability (anisotropy coefficient of 2,09 %) was observed, in addition to the low content of extractives (1,94 %). From the mechanical characterization, an average value for the elastic modulus of 8963 MPa was obtained, and for the compressive strength parallel to the grain the average and characteristic values were 32,14 MPa and 21,46 MPa, respectively. This indicates that this wood belongs to resistance class C20 (dicotyledons). The results obtained classify the wood for use in light, external, or internal civil construction

圣保罗州栽培的油桐的物理、化学和力学特性

印度雪松(Acrocarpus fraxinifolius)是一种天然生长于印度、缅甸和孟加拉国的树种，具有红木和本土雪松等特点，具有很高的商业价值。巴西已经开始种植印度雪松，但关于该树种特征的资料很少。因此，考虑到其木材潜力及其在该国发展的可能性，本研究旨在评估种植在巴西南部地区的9年树龄印度雪松木的物理、化学和机械特性。其比质量低(502 kg/m3)，平均尺寸稳定性低(各向异性系数为2.09%)，萃取物含量低(1.94%)。通过力学特性分析，得到弹性模量平均值为8963 MPa，平行晶抗压强度平均值为32、14 MPa，特征值为21、46 MPa。这表明该木材属于抗级C20(双子叶)。获得的结果分类木材用于轻型，外部或内部民用建筑
