Hybrid Particleboard Made from Bamboo (Dendrocalamus asper) Veneer Waste and Rubberwood (Hevea brasilienses)

Abstract

This study investigated adhesion properties, such as buffering capacity and wettability, of bamboo and rubberwood and evaluated the physical and mechanical properties of hybrid particleboard made from bamboo (B) veneer waste and rubberwood (RW) particles. The bamboo had an acidic pH value with a high buffering capacity compared with rubberwood. Hybrid bamboo-rubberwood particleboard displayed better mechanical properties compared to 100% bamboo and rubberwood particleboard. All hybrid particleboard panels passed and fulfilled the minimum standard requirements, except for thickness swelling and water absorption tests. However, for thickness swelling test, only boards consisting of 50B:50RW and 30B:70RW passed and fulfilled the minimum TS requirements of the British Standard EN 317 (1993). Panels made from 100% bamboo veneer waste displayed the highest modulus of rupture (MOR) and modulus of elasticity (MOE) values, 15.30 N/mm 2 and 2650.14 N/mm 2 , respectively. Hybrid particleboard panels exhibited better screw withdrawal compared with panels made of only bamboo or rubberwood particles. It is concluded that bamboo veneer waste enhances the quality of particleboards, especially in terms of mechanical strength. Thus, bamboo veneer waste can decrease the dependence of the particleboard industry on rubberwood.

Effect of Particle Size on Bamboo Particle Board Properties

“…Considering that the compaction ratio of panels practically did not vary and was low (Table 2), this may explain why TS values were also low. Nurhazwani et al (2016) produced homogeneous single-layer particleboards using bamboo particles (Dendrocalamus asper) and rubber tree (Hevea brasiliensis) particles, both from a single granulometric class (-10+35 mesh), isolated and mixed at different proportions. Particles were glued using urea-formaldehyde-based adhesive at 12% content and panels were produced with nominal density and thickness of 0.70 g/cm 3 and 12 mm, respectively, without the addition of paraffin.…”

“…Several studies on the experimental manufacture and particleboard quality using different bamboo species and wood particles, isolated or mixed, have been carried out; for example, those conducted by Vital & Haselein (1988), Calegari et al (2007), Arruda et al (2011), Morais (2011), Melo et al (2014, Valarelli et al (2014), Morais et al (2015), Nurhazwani et al (2016). Among these studies, only that carried out by Nurhazwani et al (2016) used Dendrocalumus asper bamboo, and none of them addressed the influence of particle size on panel properties.…”

The Possibility to Use Long Fibres from Fast Growing Hemp (Cannabis sativa L.) for the Production of Boards for the Building and Furniture Industry

“…This straw can be successfully glued with resins such as UF, PF, or MUPF (Dziurka et al 2005). Hybrid boards containing alternative materials that partly displace wood are becoming increasingly popular (Nurhazwani et al 2015).…”

“…Bamboo is a fast growing plant that could be very important for the production of large-size panels based on lignocellulosic particles (Abdul Halip et al 2014;Nurhazwani et al 2015;Jin et al 2016;Zhou et al 2016). Hemp is another alternative to wood that can be used for manufacturing boards.…”

Enhancement of the Mechanical Properties and Dimensional Stability of Oil Palm Empty Fruit Bunch-Kenaf Core and Oil Palm Mesocarp-Kenaf Core Hybrid Fiber-Reinforced Poly(lactic acid) Biocomposites by Borax Decahydrate Modification of Fibers

“…Current research in the area of polymer composites has experienced increasing attention in the fabrication of natural fiber-based hybrid systems aiming to achieve synergistic performance, complement material properties, and a sustainable supply chain of fiber resources (Jacob et al 2004;Ghasemi et al 2008;Thiruchitrambalam et al 2009;Jawaid et al 2010;Othman et al 2016). Recently, the hybridization of cellulose-rich oil palm fibers (OPFs) and lignin-rich kenaf core fiber (KCF) into the poly(lactic acid) PLA matrix has been reported by our research group, presenting enhanced mechanical properties and dimensional stability relative to single fiber biocomposites (Birnin-Yauri et al 2016) However, optimum synergism in material properties of hybrid natural fiber-based thermoplastic composites is realizable with modification of the natural fibers (Thiruchitrambalam et al 2009).…”
