dc.description.abstractIn this study the optimization of drying oil palm trunk core lumber (OPTCL) biomass using microwave radiation was reported. Optimizing of the drying conditions using microwave could avoid burning, shrinkage and increasing the permeability of OPT was aimed to develop a new value added material. Drying the core part of oil palm trunk using microwave was completed in this study for the first time. A set of experiments was designed by central composite design using response surface methodology (RSM) to statistically evaluate the findings and developed a model to predict drying prameters. Three independent process variables including time (2, 4, 6, 8, 10 min), sample weight (300, 475, 650, 825, 1000 g) and input power (660, 1320, 1980, 2640, 3300 W) were studied under the given conditions designed by Design Expert software. The results showed the effectiveness of microwave drying in reducing the time and better removal of moisture as compared to that of oven drying with no significant changes. Employing optimum conditions at 6.89 min of time with a microwave power set at 4 for a sample of 1000 g, predicting 14.28% of moisture content. The microwave dried oil palm trunk core part was impregnated with phenol formaldehyde (PF) resin as a matrix using high-pressure vacuum impregnation chamber. Oil palm trunk core lumber (OPTCL) was impregnated in different times and compared with Rubberwood (RW). The mechanical, physical, and thermal properties were studied according to BS and ASTM standards. On average, the microwave dried impregnated oil palm trunk core lumber (OPTCL) exhibited higher physical and mechanical properties than dried one. The properties of OPTCL impregnated for 60 min was slightly lower than RW except in water absorption and thermal stability which was comparable and even higher than RW. The morphology of resin loaded oil palm trunk core which was analyzed by scanning electron microscopy (SEM) showed full penetration of resin into OPTCL cell.en_US
