Resumo: The present study aimed to determine the static bending and the apparent specific gravity of Inga marginata wood in different humidity conditions. Three individuals were cut at an approximate age of six years. For determination of the studied properties, we followed the recommendations of ASTM D143-94 norm. We observed reduction of more than 1.2 times the modulus of elasticity, modulus of rupture, tension at the proportional limit and maximum force in the static bending as a function of fiber saturation. In general, the samples presented smaller apparent specific gravity values and higher mechanical resistance according to the desorption until the equilibrium moisture of 12%. The wood, in this condition, was classified as moderately heavy.

Foram abatidos três indivíduos com, aproximadamente, seis anos de idade. Para a determinação das propriedades estudadas foram seguidas as recomendações da norma ASTM D143-94. Observou-se redução superior a 1,2 vezes do módulo de elasticidade, módulo de ruptura, tensão no limite proporcional e força máxima na flexão estática em função da saturação das fibras. De maneira geral, as amostras apresentaram valores de massa específica aparente menores e maior resistência mecânica conforme a dessorção até a umidade de equilíbrio de 12%, sendo a madeira, nessa condição, classificada como moderadamente pesada.Embrapa Florestas2018-12-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/167110.4336/2018.pfb.38e201801671Pesquisa Florestal Brasileira; v. 38 (2018)Pesquisa Florestal Brasileira; Vol. 38 (2018)1983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/1671/815https://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessCandaten, LuanaRodrigues, Edivane FrancielliTrevisan, RômuloEloy, ÉlderFontoura, Mágda Rosa2019-05-10T19:43:48Zoai:pfb.cnpf.embrapa.br/pfb:article/1671Revistahttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/PUBhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/oaipfb@embrapa.br || revista.pfb@gmail.com || patricia.mattos@embrapa.br1983-26051809-3647opendoar:2019-05-10T19:43:48Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
