Resumo: | This work aimed to characterize the wood of Hovenia dulcis Thunberg, to be used in the manufacture of floors. Five trees obtained in Araucaria Forest were used for the technological characterization. The trees had, in average, 18 years old. After logging, they were measured to determine their volume. The logs were sawed into boards and blocks to determine the basic specific mass, Janka hardness (base log) and in-service floor simulation tests (middle and top logs). The boards and blocks were dried before the test samples preparation. We considered samples of 100% of heartwood and composed of heartwood and sapwood. H. dulcis was characterized as wood of medium specific mass (0.54 g cm-³) and medium strength (5,851.99 N). For all in-service floor simulation tests, H. dulcis wood showed superior or similar resistance to other exotic species and inferior to native hardwood species found in the literature. It was concluded that the wood under study shows low strength for maximum efforts and can be used on floors for light traffic or in places where loads are low. |

Para a caracterização tecnológica, foram utilizadas cinco árvores obtidas em Floresta Ombrófila Mista. As toras foram mensuradas, para a determinação do seu volume. Posteriormente, foi realizado o desdobro das mesmas em tábuas e blocos, para a determinação da massa específica básica, dureza Janka (tora da base) e ensaios de simulação de piso em serviço (toras do meio e topo). As tábuas e os blocos foram secos, para posterior preparação dos corpos de prova. Esses foram confeccionados separando-se a madeira constituída com 100% de cerne daquela que apresentava cerne e alburno. A madeira de H. dulcis caracterizou-se como de média massa específica (0,54 g cm-³), com média resistência (5.851,99 N). Em todos os testes de simulação de piso em serviço, a madeira de H. dulcis proporcionou resistência superior ou semelhante a outras espécies exóticas e inferior a espécies folhosas nativas encontradas na literatura. Concluiu-se que a madeira em estudo apresenta baixa resistência para esforços máximos, podendo ser utilizada em pisos para trânsito leve ou em locais em que as cargas são baixas.Embrapa Florestas2020-12-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/octet-streamhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/190510.4336/2020.pfb.40e201901905Pesquisa Florestal Brasileira; v. 40 (2020)Pesquisa Florestal Brasileira; Vol. 40 (2020)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/1905/1620Copyright (c) 2020 Raquel Marchesan, Morgana Cristina França, Pedro Licio Loiola, Márcio Pereira da Rocha, Ricardo Jorge Klitzke, José Reinaldo Moreira da Silvahttps://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessMarchesan, RaquelFrança, Morgana CristinaLoiola, Pedro LicioPereira da Rocha, MárcioKlitzke, Ricardo JorgeMoreira da Silva, José Reinaldo2020-09-28T20:35:31Zoai:pfb.cnpf.embrapa.br/pfb:article/1905Revistahttps://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:2020-09-28T20:35:31Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
