Bamboo Fibers

In this study, bamboo polymer composites (BPC) reinforced with bamboo fibers were produced and analyzed. The effect of alkalization on the mechanical and physical properties of the composites were determined. Three levels of bamboo fiber content (10%, 20% and 30%) of alkali treated and untreated bamboo fibers were considered. Six replications of each type of test specimens were prepared and investigated under bending, tensile, water absorption and thickness swelling tests. From the results, increase in fiber content and alkali treatment of the fibers improved the mechanical properties of BPC. The value of water absorption (WA) and thickness swelling (TS) increased as the fiber content was increased and also as the fibers were treated. The value of WA and TS of the BPC with treated bamboo fibers were higher than the values for the BPC with untreated bamboo fibers.

This study investigated the effects of the pressing temperature on the mechanical and physical properties of binderless bark particleboard made from Gelam bark waste and the improvement of those properties. In addition, the thermal insulation properties of the particleboard were determined. Four different temperatures (140 °C, 160 °C, 180 °C, and 200 °C) were used to make single-layer binderless bark particleboard with a target density of less than or equal to 0.59 g/cm3. Results revealed that the pressing temperature affected the mechanical properties (modulus of rupture, modulus of elasticity, and tensile strength perpendicular to panel surface), which increased as the temperature increased, and the physical properties (thickness swelling and water absorption), which decreased as the temperature increased. Based on the Tukey test, increasing the temperature from 180 to 200 °C did not significantly affect the mechanical or physical properties, except for the tensile strength perpendicular to panel surface. None of the mechanical properties met SNI standard 03-2105-2006 (2006); however, the 12% maximum thickness swelling requirement was met for binderless bark particleboard hot-pressed at 200 °C. Binderless bark particleboard hot-pressed at 200 °C had high water resistance, regardless of its low strength, and a thermal conductivity value of 0.14 W/m∙K.

Fiberglass Composite

Bamboo is considered as environmentally and eco-friendly material compared to hardwood and nowadays bamboo veneer is getting very popular in the market. Bamboo veneer is suitable for many modern designs. The alternate layers of veneer bamboo (3 and 5 layers) were combined with fiberglass by using Epoxy resin (2% hardener) as bonding agent to produce PBFC at different pressure. Panels produced were assessed for the mechanical and physical properties such as MOE and MOR, thickness swelling (TS), and water absorption (WA) in accordance with the European Standard. Results revealed that strength performance of board improved with increasing pressure. Thickness swelling and water absorption values were much lower for the 5 layer composite Thus such findings revealed that bamboo veneer from Buluh betong possess great potential for the manufacture of bio-composite products.

This study was done to investigate the effects of ozone treatment as a method to improve the properties of empty fruit bunch (EFB) medium density particleboard. Two types of EFB were used in this study i.e. screw pressed and non-screw pressed empty fruit bunch. These EFB were treated in an ozone chamber for 8 hours prior to particleboard manufacturing. The mechanical properties, Modulus of Elasticity (MOE), Modulus of Rupture (MOR) and Internal Bonding (IB) and physical properties, water Absorption (WA) and Thickness Swelling (TS) of EFB particleboard were determined. The results showed that the ozone treatment could increase the MOR and IB values of EFB particleboard, but had no significant effect on MOE values. For physical properties, the values showed no improvement for TS and WA. The panels manufactured using ozone treatment was found suitable for applications for furniture products.

This research aims to find out the effect of cement-saw dust ratio levels on the physical and mechanical properties of produced composites. The physical properties (density, water content, water absorption after the immersion of one hour and 24 hours, and thickness swelling after the immersion of one hour and 24 hours) and mechanical properties (MOE and MOR) were observed according to ISO standards. The results showed that the use of the cement to sawdust ratio of 3 : 1 in producing wood composite with the target density of 1200 kg/m3 resulted in the lowest water absorption and the highest MOE and MOR. The swelling value and MOR of the produced boards were not acceptable, but their water content, water absorption, and MOE parameters were acceptable according to ISO 8335 1997.

Trewia Nudiflora

The study was conducted to find out the potentiality of Pitali (Trewia nudiflora) for manufacturing commercial plywood and evaluating its physical and mechanical properties. Two 9-ply plywood of 2.4m x 1.2m x 18mm size were manufactured using liquid urea formaldehyde adhesive. The physical and mechanical properties of T. nudiflora plywood were compared with the existing market available plywood manufactured by Simul (Bombax ceiba). It was found that density were 509.82 kg/m3 and 490.96 kg/m3, moisture content after curing were 10.67% and 17.61%, thickness swelling were 6.90% and 7.29%, linear expansion were 0.19% and 0.15%, water absorption were 50.89% and 64.79%, MOR were 29.94 N/mm2 and 27.05 N/mm2, MOE were 1613.89 N/mm2 and 1160.68 N/mm2, and tensile strength were 14.75 N/mm2 and 13.12 N/mm2 for T. nudiflora plywood and market plywood respectively. The evaluated physical and mechanical properties of T. nudiflora plywood were also compared with some relevant results and standards reported earlier.

Four Levels

Effects of two widely available and underutilized lignocellulosic materials on the mechanical and physical properties of particleboards were investigated in this work. The ratio of mixtures lignocellulosic flakes at four levels (100% aspen wood), (50% aspen wood: 25% citrus: 25% old railroad ties), (50% aspen wood: 50% citrus), and (50% aspen wood: 50% old railroad ties), and the percentage of resin in two levels (8 and 12%) were considered as variable factors. The 100% aspen wood (Populus tremula) was mixed as a control board (100% aspen wood). Then the mechanical and physical properties of the samples including modulus of rupture, modulus of elasticity, internal bond, water absorption, and thickness swelling after 2 h and 24 h of immersion (EN 310-319) and fire resistance (ISO 11925-2) were measured. The results showed that with increasing poplar wood in mixtures, modulus of rupture, modulus of elasticity, internal bond increased, while water absorption and thickness swelling decreased. Also, in comparison with the control boards, the boards that were made by mixing 50% poplar and 50% citrus branches with 12% glue had the highest mechanical strength. The results also showed that increasing the amount of old railroad ties chips in mixing caused a significant decrease in the fire retardancy of the boards.

Loading Amount

Effect of nanoMagnesium Hydroxide (MH) nloading amount to the mechanical and physical properties of Low Density Polyethylene (LDPE)/ Poly (ethylene-co vinyl acetate)(EVA) nanocomposite has been described and investigated in this paper. The tensile strength results show that increased amount of nanofiller will decrease and deteriorate the mechanical properties. The elongation at break decreased continuously with increasing loading of nanofiller. Generally, mechanical properties become poorer as loading amount increase. Melt Flow Index values for physical properties also provide same trend as mechanical properties results. Increase filler amount reduced MFI values whereby increased resistance to the flow.
