This research aims to study the using oil palm fiber to develop pseudo-plywood from polyethylene product. The mixture ratios of oil palm fiber : polyethylene are 50 : 50 55 : 45 60 : 40 65 : 35 and 70 : 30 by weight. The pseudo-plywood samples are cast in 30 x 30 x 1.5 centimeter in dimension. The pseudo-plywood sample testing follows the TIS 966-2547. The results show that the density bending strength modulus of elasticity thermal conductivity and tension perpendicular to surface of pseudo-plywood with high quantity of oil palm fiber are lower than pseudo-plywood with low quantity of oil palm fiber while that the water absorption and swelling by density of pseudo-plywood with high quantity of oil palm fiber are higher. However all of oil palm fiber samples with lower than 65 of ratio can pass the standard.

The objectives of this research are to study the production to find the proper ratio to test the properties to suggest the implementation and to transfer the technology of high strength milk carton waste artificial wood mixed with poly ethylene terephthalate (PET) plastic waste. The ratios of this artificial wood included milk carton waste: PET plastic waste equal to 80:20 75:25 70:30 65:35 and 60:40 by weight. The milk carton and PET plastic wastes were grinded though sieve no.4. The artificial woods were casted by hot compression with 180 degree of Celsius for 5 minutes. The samples tested follow the TIS.966-2547 standard. From the results the 60:40 of ratio was the proper ratio which can pass the standard. The increasing of PET waste effected to decrease the density moisture and swelling of properties. In case of bending strength elastic modulus and tensile strength perpendicular to surface the increasing of PET effected to decrease their properties. The developed artificial wood mixed with milk cotton waste and PET plastic waste has the possibility to implement in decoration and construction both interior and exterior wall building. These results can register the petty patent and write the research paper which to transfer the technology.

This research work was to study the effect of moisture on mechanical properties of wood/polyvinylchloride composites (WPVC). WPVC specimens in ratio of PVC and wood (100:100 by weight) were prepared by using twin screw extruder. The water conditions for WPVC specimen immersion testing were varied for temperatures of 30-70 oC and specimen immersion time of 0-120 h. The moisture effect was investigated by measuring flexural properties and hardness of WPVC as comparing with case of PVC specimen. The result suggested that flexural modulus of WPVC tended to decrease with increasing time of water immersion and then remained unchanged at immersion time of more than 72 and 48 h for water temperature of 30 and 70 oC respectively. The decrease rate in flexural modulus enhanced when water temperature increased. Flexural modulus of PVC slightly changed with increasing both immersion time and water temperature. Flexural strength for both PVC and WPVC specimens were found the change at water temperature of 70 oC only. Flexural strength of PVC tended to slightly increase with increasing immersion time whereas flexural strength of WPVC slightly decreased with increasing immersion time. Hardness of PVC specimen in cases of both water temperature of 30 and 70 oC slightly increased with increasing immersion time. For WPVC hardness tended to decrease with increasing immersion time and water temperature.
