Mechanical analysis of bamboo and agro-industrial residue one-layer particleboard

Abstract

A high-density particleboard composed of peanut shells (Arachis hypogaea L.), an agro-industrial residue, and bamboo wastes of the species Dendrocalamus giganteus (branches and apical part), bonded with a two-component polyurethane resin based on castor oil (Ricinus communis L.) in the proportion of 12% of the particleboard mass, was produced. Four types of specimens were prepared according to the percentage of peanut shells: 0%, 10%, 20%, and 30%. Mechanical characteristics were evaluated through the flexural strength tests for modulus of rupture, modulus of elasticity, perpendicular traction, and screw pull resistance. The particleboard reached an average density of 917.2 kg/m3, meaning that it could be classified as high-density particleboard. The results of the mechanical tests indicated that the specimens containing a mixture in the proportion of 90% bamboo and 10% peanut hull presented the best mechanical strength. The experiment produced particleboards with a satisfactory mechanical physical performance that met the standards ABNT NBR 14.810-2 and ANSI A208-1, supporting the use of the peanut shell residue in the manufacture of particleboards to be used in internal environments and allowing the applicability of this residue through additional value.

Technological Properties of Medium Density Particleboards Produced with Peanut (Arachis Hypogaea) and Pinus Oocarpa Hulls

“…Similar trends were reported in the literature as Guler et al (2008) and Nasser et al (2020). Guler et al (2008) found that increasing the percentage of peanut hulls in the composition of the panels significantly decreased the mechanical properties.…”

“…The values obtained for the MOR ranged between 9.90 and 15.54 MPa and for the MOE the values found were between 1,276.76 and 2,145.71 MPa. Nasser et al (2020) observed that the increment of peanut hulls in the composition of the panels was also responsible for a reduction in the strength of MOR and MOE. For the MOR the composition of the panels with 100% bamboo particles showed the highest value and the composition with higher content of peanut hulls evidenced the lowest value.…”

“…With the results obtained, it was possible to verify that the incorporation of wood particles provided an increase in the physical-mechanical properties of the particleboard with peanut shell. Nasser et al (2020) manufactured high-density panels composed of peanut hulls (Arachis hypogaea L.) and bamboo waste (branches and apical part), using two-component polyurethane resin based on castor oil (Ricinus communis L.). The performance of the panels complied with the ABNT NBR 14.810-2 and ANSI A208-1 standards, supporting the use of peanut hull waste in the manufacture of particleboard panels for indoor use and allowing the applicability of this through additional value.…”

“…Then, the glued particles were manually distributed in a wooden box with internal dimensions of 40 x 40 cm to form the mattress and ensure a more homogeneous distribution. According to Nasser et al (2020) this step is essential to ensure that there are no changes in the properties of the particleboard due to the variation in density between the regions of the mattress.…”

Wettability and decay of particleboards manufactured with thermally treated sugarcane residue and bamboo (Dendrocalamus asper) particles

“…Brito et al (2020a) concluded that bamboo can be used as an alternative material for the manufacture of particleboard for indoor uses. Nasser et al (2020) verified panels made of bamboo and peanut shells met the parameters established by Brazilian Standard -NBR 14.810-2 (2013), Brazilian Association of Technical Standards -ABNT (2013) and American National Standards Institute -ANSI A208-1 (1999).…”
