Resumo: | The objective of this study was to verify the efficiency of nondestructive evaluation of wood panels mechanical properties by stress wave timer method in medium density particle board (MDP) from pine. Were evaluated industrial MDP panels from eucalypts (5) and pine (5), both from two national companies, and five panels from sugarcane bagasse imported from China. Stress wave timer method was used for nondestructive evaluation. The modulus of elasticity (MOEd) obtained by stress wave timer method was confronted with MOE and flexural strength (MOR) to bending tests from conventional assays. Measures in length and width directions were performed in each panel. Nondestructive method was effective only for sugar cane bagasse panels, so it can be used to predict MOE and MOR for this type of panel. |

Foram avaliados painéis MDP industriais, sendo cinco de eucalipto e cinco de pinus, ambos provindos de empresas nacionais, e outros cinco painéis de bagaço de cana importados da China. Para a avaliação não destrutiva dos painéis, foi utilizado o equipamento Metriguard, que utiliza o método de emissão de ondas de tensão Stress Wave Timer. O módulo de elasticidade (MOEd) obtido pelo método de stress wave timer foi confrontado com os valores determinados por meio de ensaios convencionais destrutivos de MOE e módulo de ruptura (MOR) à flexão estática. Em cada painel foram realizadas leituras nas direções longitudinal e transversal dos painéis. O método não destrutivo stress wave timer apresentou eficiência apenas para a utilização em painéis de bagaço de cana, podendo ser utilizado para predição do MOE e MOR desse tipo de painel.Embrapa Florestas2017-09-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/107110.4336/2017.pfb.37.91.1071Pesquisa Florestal Brasileira; v. 37 n. 91 (2017): jul./set.; 243-247Pesquisa Florestal Brasileira; Vol. 37 No. 91 (2017): jul./set.; 243-2471983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/1071/583https://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessOliveira, Stefânia LimaMendes, Rafael FarinassiMendes, Lourival MarinNarciso, Carolina Rezende PintoRibeiro, Débora Pereira2018-05-24T12:03:03Zoai:pfb.cnpf.embrapa.br/pfb:article/1071Revistahttps://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:2018-05-24T12:03:03Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
