Structure and Quality of Medium Density Fiberboard (MDF) Made fromAgricultural Fiber

ABSTRACT

In order to better utilization of agricultural fibers as an alternative resource for composite panels, several variables were investigated to improve properties of agro-based medium density fiberboard (MDF). MDF products are increasingly utilized in traditional wood applications that require high quality. The utilization of agricultural fiber such as pineapple leaf fiber to wood substitution as fiberboard material are not much investigated yet at present. The aim of this research are: (1) to examine the structure and quality of pineapple leaf fiber as fiberboard material, (2) to evaluate termite resistance of MDF under various concentration of urea-formaldehyde (UF) resin and additive matter. Quality and structure of pineapple leaf fiber was determined by using X ray difracto-meter at temperature of 170°C and GCMS at temperature of 150°C. MDF were prepared under various concentrations of UF resin (16%, 18% and 20%) and liquid paraffin (0%,
1% and 2%). The result shows that pineapple leaf fiber has crystallinization level of 46.47% which
was can be used as fiberboard material. Vollatile matter produce from pineaplle leaf fiber mostly containe acid compound. In general, as adhesive and additive matter increasing then the physical and mechanical properties of fiberboard are increasing. The good quality of MDF was noted at concentration of UF resin of 20% and concentration of liquid paraffin of 2% with MOE value of
15682 Kg/cm2 ; MOR value of 362.507 Kg/cm2; screw withdrawal value of 89.244 Kg and
Internal bond strength value of 2.02 Kg/cm2. Examination to C. curvignathus revealed that the
percentage of mortality of termite was reach 100% at two week observation. This could be explain that acid compound may influence the death of termite. This is indicated that pineapple fiber was suitable used for fiberboard material.
