Substantial quantities of senile coconut palms are present in plantations within the Asia-Pacific region. Once coconut palms become over-mature, their production of traditional products, such as coconuts, significantly decreases, resulting in profitability challenges for farmers. Presently, few profitable markets exist for over-mature, senile coconut palms. Using the coconut palm stem in composite or engineered wood products could, however, provide an attractive alternative. Due to some of its unique characteristics, a processing system able to recover wood from the high-density zone near the stem periphery is desirable. A series of rotary veneer laboratory trials were undertaken to establish fundamental benchmark lathe settings and veneering characteristics for coconut palm stems. Different pressure bar configurations, billet pre-treatment temperatures, and veneer thicknesses were tested, and the resulting cutting forces and veneer quality were assessed. Optimal setting recommendations for peeling coconut wood are provided.

Root cause and vibration analysis is applied to a veneer peeling lathe to increase its efficiency and reduce wood waste. Excessive veneer thickness variations, repetitive damage of machine component and high vibration levels of the lathe are identified as interrelated issues. A root cause analysis is conducted to finally select both design and operating factors, which were then investigated to quantify their effects on the vibratory lathe response and process efficiency. On-site vibration measur...

Abstract Balsa wood is an appropriate core material for structural sandwich applications due to its high strength- and stiffness-to-weight ratios. However, the mechanical properties vary considerably owing to the inherent scattering of natural wood materials. One approach to reduce this scatter and tailor the mechanical properties according to specific application needs is to recompose the natural material into a veneered material consisting of veneer layers of different grain orientations, whic...

Abstract The tensile, compressive and shear behavior of standardized specimens cut from a veneered balsa wood used as structural sandwich core was investigated at ambient temperatures of up to 250 °C. The average moisture content was 9.1%. The specimens’ responses were strongly affected by the configuration of the veneer layers. Specimens with a higher number of 0° veneer layers in the loading direction exhibited higher strength and stiffness at each temperature. Independent of the loading type,...

Rubber forest plantation (RFP) in Malaysia was currently governed by small holders who provided lower diameter logs as they managed plantation using higher planting density, higher frequency tapping practice and young-tapping systems to enhance latex harvesting yield and fulfil demand for rubber timber. Nevertheless, these new planting systems will affect the growth of rubber tree and result in the production of smaller diameter (< 20 cm) rubber logs compared to conventional planting systems. He...

High quality and high density coconut veneer and veneer-based product are new to the marketplace. Their likely acceptance can only be estimated from observation of the material’s properties, the performance requirement of potential applications, and the acceptance of similar (or competitor) products in those applications in the market. The form and material properties of coconut palms significantly influences the potential functionality of recovered coconut wood and veneer products. The distribu...
