Propriedades mecânicas de amostras individualizadas da madeira e do carvão de Eucalyptus urophylla e de Corymbia citriodora

Abstract: ResumoEste trabalho teve como objetivo caracterizar mecanicamente amostras individuais da madeira e do carvão vegetal de Corymbia citriodora e de clones de Eucalyptus urophylla, por meio de ensaios de compressão paralela às fibras e de flexão estática, e ainda, correlacionar as propriedades da madeira com as do carvão produzido. Foram utilizadas 148 amostras, sendo que 74 foram destinadas à avaliação do carvão e 74 à avaliação da madeira. As amostras destinadas ao processo de carbonização foram submetidas a um… Show more

“…The high correlation between hardness and density is in agreement with the findings reported by Antal et al and Chrzazvez et al, who evaluated the relationship between density and mechanical strength. According to data found in the literature, there is a positive correlation between the basic density of wood and the elasticity modulus, the compressive strength parallel to the carbon fibers, and the gravimetric yield and density of charcoal. , Moreover, charcoal produced with denser woods presents higher density and lower friability…”

“…Wood presenting a high density tended to produce less brittle and denser charcoal . Therefore, charcoal produced from dense woods is expected to exhibit higher mechanical strength.…”

“…Segundo Veiga [9] ao estudar espécie de C. citriodora, constatou um valor de 0,71 g/cm³ para densidade básica. Morais [10], observou um valor de densidade básica de 0,546 g/cm³ para a espécie de Eucalyptus grandis.…”

“…Veiga [21] notou ao analisar a madeira de Corymbia maculata com 7 anos de idade com uma densidade básica de 0,705 g/cm³ um módulo de elasticidade de 9116 MPa, valor muito inferior ao encontrado no presente estudo, isso se justifica pela diferença de idade, sendo a espécie aqui analisada com 22 anos de idade.…”
