Resumo: This study aims to manufacture plywood panels with both graded plies (by visual and acoustic wave methods) and ungraded plies (randomly selected), bonded together in different arrangements, and also to verify the effect of these techniques on the specific mass, strength and stiffness against static bending and binding strength of finished panels. Plywood panels manufactured exclusively with superior quality plies, as graded by the acoustic wave method, and plywood panels manufactured exclusively with randomly selected plies had better performance, with no significant differences being noted between them, except for specific mass.

O compensado produzido integralmente com lâminas de maior qualidade, classificadas pelo método de aplicação de ondas acústicas, e o compensado produzido integralmente com lâminas selecionadas aleatoriamente, foram os que apresentaram a melhor performance, sem diferenças significativas entre si, exceto para a massa específica.Universidade Federal de Lavras (UFLA)2015-05-152017-08-01T20:13:43Z2017-08-01T20:13:43Z2017-08-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/pdfBORTOLETTO JÚNIOR, G.
