“…Furthermore, thermosetting wood composites have been investigated in mechanical properties. Ayrilmis et al [28] have studied the mechanical properties, modulus, and strength under flexure mode of particle boards based on phenol-paraformaldehyde and woodflour/rice husk particle mixtures (89-92 % by weight). The flexural modulus and strength of particle board have been reported from 2.3 to 2.6 GPa and from 12.8 to 14.0 MPa, respectively.…”

Wood-substituted composites of natural woodflour-filled polybenzoxazine and theirs polybenzoxazine alloys with high mechanical properties, good thermal stability, and reduced water uptake have been developed. The outstanding compatibility between the woodflour and the polybenzoxazine-based polymer matrix is evidently seen from the large improvement in the composite's mechanical properties, glass-transition temperature (T g ), and char yield as also evidently seen in the fracture surface of the wood polymer composites based on polybenzoxazine. At the optimal woodflour content of 70 % by weight in polybenzoxazine results in the composite's T g as high as 200°C or about 40°C greater than that of the neat polybenzoxazine and the modulus in a range of 6.4-6.8 GPa compared to that of natural Hevea brasiliensis wood, i.e., 9.7 GPa. Polybenzoxazine is thus proved to be useful as an effective binder for lignocellulosic materials such as woodflour.

“…It was reported that the mechanical properties of the PF resin bonded samples were better than those of the UF resin-bonded samples. 25 In the study of Klimek, the effects of both filler materials and resins were investigated. Germany-grown cup-plant (Silphium perfoliatum L.), sunflower (Helianthus annuus L.) and topinambour (Helianthus tuberosus L.) were used as raw materials, while methylene diphenyl diisocyanate (MDI) and urea formaldehyde (UF) were used as resins to produce particleboard.…”

In this study, polymeric composite particleboard has been manufactured from orange peel, which is an abundant and promising agricultural waste in Turkey. An urea-formaldehyde (95 wt%) and phenol-formaldehyde (5% wt) mixture was used as polymeric binder and waste orange peel as a filler for the production of particleboard. The effect of polymeric binder/filler ratio on the tensile strength, limit oxygen index and water absorption capacity of the composite materials were determined. The molding temperature and pressure were set to 120 °C and 2 Mton, respectively. The highest tensile strength was obtained as 15 MPa at an equal polymer/orange peel ratio. Both mechanical strength and LOI (limiting oxygen index) values increased with increasing polymeric binder amount in the particleboard. However, water absorption capacity values decreased from 0.35 g water/g material to 0.16 g water/g material, with increasing amount of the polymeric binder. Considering the properties of the developed polymeric composite material, it can be concluded that orange peel waste can be used as a filler to replace wood-based materials in the production of particleboard.

“…In 2014, the particleboard production was 111 M m 3 worldwide. Most commercial particleboard is produced using the dryforming process, bonded with adhesives, such as urea formaldehyde (UF) resin, phenol formaldehyde (PF) resin (Ayrilmis et al 2012), and even with diphenylmethane diisocyanate (MDI) resin in special conditions (Kojima et al 2009). However, formaldehyde emission has been an ever-increasing health issue.…”

Wet-formed particleboard bonded with cellulose nanofibrils (CNF) was prepared in this work. The effects of density, CNF addition ratio, pressing method, and particle size on the bending strength were evaluated. The results showed that density had the most important effect on the modulus of elasticity (MOE), while the CNF addition ratio had the most important effect on the modulus of rupture (MOR). For panels with low density (< 640 kg/m 3 ), the MOE and MOR did not change much with the configuration changes between particle size and pressing method. This was due to the synergistic effect of incomplete compression and poor bonding in the core area using a constant thickness (CT) pressing method, and lower face density and higher core density using a constant pressure (CP) pressing method. For panels with medium density (640 kg/m 3 to 800 kg/m 3 ), the combination of larger particles, higher CNF addition ratio, and CT pressing method contributed to the highest bending strength. Further increase to high density (> 800 kg/m 3 ), the pressing method's effect was more important, compared to panels with low and medium densities. With increased density and CNF addition ratio, panels were able to meet lowdensity and some medium-density standard MOE and MOR requirements.
