“…As of January 2021, there were 116 and 222 publications with the keywords "particleboard" and "bamboo", respectively, from the Scopus and Science Direct databases. The number of publications has more than doubled, compared with a report by [2], which found 53 publications as of 2016. Furthermore, a search using the keyword "particleboard" paired with the bamboo species Dendrocalamus asper yields 11 publications in the Scopus database and 10 in Science Direct.…”

“…Backer is a bamboo species with a wide distribution in tropical and subtropical areas, especially in Southeast and South Asia [3]. This species is referred to by various names, including betung, petung, batuang, and betho [3] which has also been introduced in many areas of the world including Latin and South America [2]. Commonly known as giant bamboo or rough bamboo, the bamboo is tall having large culms when it is mature at the age of 3 to 5 years.…”

“…Due to its thick and strong shells, D. asper culm is mainly used as a building component, in addition to the widely used manufacture for furniture, musical instruments, and household appliances [3]. The trend of using bamboo continues to increase and has even become a lifestyle, especially in Asia and some parts of South America [2]. In addition to the traditional uses of bamboo culm, bamboo has drawn interest for use in the manufacture of various composite panels including particleboard.…”

The objective of this study was to evaluate various physical and mechanical properties of experimental particleboard panels made from Asian giant bamboo (Dendrocalamus asper). Single layer panels having a density level of 0.75 g/cm3 from coarse and fine particles were used within the scope of this study. Thickness swelling, water absorption, surface roughness, and wettability characteristics of the samples were tested as physical properties while bending, internal bond strength, and screw withdrawal strength of the panels were considered for their mechanical properties. Resistance of the panels against termite and fungus were also determined. Based on the findings in the work both physical and mechanical properties of the panels made from coarse particles resulted in higher values than those made from fine particles with the exception of their internal bond strength. It appears that using fine particles in the panels enhanced their overall surface quality as well as wettability. Regarding biological deterioration of the samples, those made with coarse particles had better resistance. It seems that giant bamboo as a non-wood lignocellulosic species would have potential to be used as raw material to the manufacture value added particleboard with accepted characteristics.

Densification processes are used to improve the mechanical and physical properties of lignocellulose materials by either collapsing the cell cavities or by filling up the pores, consequently reducing the void volume fraction. This paper focuses on an extensive review of bamboo densification process, which is achieved by compressing the material in the direction perpendicular to the fibers using mainly two different techniques: an open system, thermo-mechanical (TM), or a closed system, viscoelastic-thermal-compression (VTC). The main aim of bamboo densification is to decrease its heterogeneity, as well as to improve its mechanical and physical performance. In addition, densification may occur during the manufacturing of bamboo products in which hot-pressing processes are used to mold bamboo panels. There are over 1600 publications about bamboo, concentrated in the recent decade, mainly about engineered materials. Although several papers regarding bamboo and wood densification are available, very few studies have comprehensively investigated the densification process solely through compression of natural bamboo culms. According to the literature, applying a combination of compression of 6–12 MPa at temperatures between 120–170 °C for 8–20 min can produce materials with higher strength in comparison to the mechanical properties of natural bamboo. The majority of research on bamboo densification indicates that the modified material results in improved properties in terms of density, hardness, bending strength, stiffness, and durability. This paper provides a review that consolidates knowledge on the concept of bamboo culm densification, discusses the roles of parameters that control the process, ascertains the best practice, and finally determines gaps in this field of knowledge.

“…O termo 'partícula' corresponde ao componente agregado de um painel aglomerado, podendo ser de madeira ou outro material lignocelulósico. No segmento industrial de base florestal constata-se, anualmente, uma crescente demanda por madeira e, com isso, as indústrias têm buscado diversificar suas fontes de matérias-primas para complementar a produção de painéis reconstituídos (MDP e HDP) (Melo et al, 2009;Stangerlin, Melo, Garlet, & Gatto, 2011;Gauss, Araujo, Gava, Cortez-Barbosa, & Savastano Jr, 2019;Talgatti et al, 2019). A matéria-prima para produção destes painéis pode ser todo e qualquer material lignocelulósico, podendo-se ainda se utilizar da mistura de diferentes fontes (Soratto, Cunha, Vital, Carneiro, & Costa, 2013;Mesquita et al, 2015;Cravo, Sartori, Fiorelli, Balieiro, & Savastano Junior, 2015).…”

The objective of this study was to evaluate the physical properties of high density particleboard (HDP) produced with pine, bamboo and co-participation of yerba mate, by means of mixtures modeling. Particles of bamboo (Phyllosttachys aurea), finely chopped sticks of yerba mate (Ilex paraguariensis) and Pinus taeda wood were used. These particles, in different proportions of mixtures, were glued in a drum-type rotary mixer with Melamine-Urea-Formaldehyde (MUF) resin, handmade molded and pressed in hydraulic press at 120 °C and 60 kgf.cm-2 for 10 minutes, up to the thickness of the 6 mm. The panels were produced with 0.90 g.cm-³ of nominal density and, after pressing, were stabilized in an air-conditioned environment at 20º C and 65% of the relative humidity. Statistical analysis follows simplex centroid planning, with seven combinations of the three components and three replicates. It was found that the apparently density, moisture content, thickness swelling (2 and 24 hours water immersion), water absorption (2 hours), are explained by the cubic model, while the water absorption (24 hours) are explained by the quadratic model. The materials used made it possible to produce high density particleboard (HDP) with physical properties that varied according to the different mixtures, however, the best results were observed for the panels produced with bamboo and Pinus taeda.
