Abstract

ABSTRACT Wood is a material used for various purposes since ancient times and is mainly used in civil and rural construction and industry. Due to the predatory exploitation of known trees, it is necessary to characterize new species for use in urban and rural structures as alternatives of species commonly used. This study aimed to determine the physical and mechanical properties of Guarucaia wood (Peltophorum vogelianum Benth.) based on the Brazilian standard ABNT NBR 7190 (1997) and estimate the strength and stiffness as a function of apparent density using the analysis of variance and also estimate stiffness as a function of its strength. The mechanical properties of P. vogelianum were considered compatible for structural use when compared with others used for the same purpose, being classified in the class C50 of dicotyledon species and evidencing the possibility of its use for structural purposes. According to the results of the poor quality in the fit of regression models in the statistical analysis, the strength and stiffness could not be estimated as a function of apparent density nor stiffness properties as a function of their respective strengths.

Highlights

Wood is a natural and renewable material that has been used by humans for various purposes since ancient times, such as shelters, tools, and supplies
Branquilho, Louro Preto, and Angelim Araroba woods are indicated for structural use (ABNT NBR 7190, 1997), reinforcing the potential use of Guarucaia wood species for this purpose
The characterization of P. vogelianum wood was adequate for structural use according to the Brazilian standard ABNT NBR 7190 (1997)

Summary

Introduction

Wood is a natural and renewable material that has been used by humans for various purposes since ancient times, such as shelters, tools, and supplies This abundant material in Brazil has been used in the construction, furniture, pulp and paper, sports equipment, and musical instrument industry (Zangiácomo et al, 2014; Beech et al, 2017; Christoforo et al, 2017a). The use of this a versatile material implies knowing all its properties (anatomical, physical, mechanical, and chemical) so that its use can be performed efficiently, meeting the environmental demands by products and services provided by society (Dias & Lahr, 2004; Machado et al, 2014; Christoforo et al, 2017b; Aquino et al, 2018). The use of wood species Peltophorum vogelianum Benth. can be considered a good alternative, occurring in the Brazilian states of Bahia, Rio de Janeiro, Minas Gerais, Goiás, Mato Grosso do Sul, and Paraná (Lorenzi, 1998)
