Research Summary: Composite materials, in general, are used in the industry because of their positive qualities such as optimized performance, minimized weight and volume, cost effectiveness, chemical and biodegradation resistance. The main purpose of this research is to develop particleboard using sago residues with adhesive of low emission Urea Formaldehyde (UF) resin with 50% solid content. The fabrication process for UF fiber boards is based on wood particle which makes the fabrication simple and economical. Boards with the densities in between 600kg/m3 to 700kg/m3 that were chosen are based on the standard wood particleboards. Sago residues from different sizes and various fibre weight fractions (90wt%, 85wt%, 80wt%, 75wt% and 70wt%) were used in the fabrication of Sago UF composite boards. The specimens were then subjected to different mechanical tests such as impact test, internal bonding test, screw test, bending test, tensile test and water absorption test. The fabrication of the particleboards was done using hot press for 6 minutes under the pressure of 40 Ton at 180°C for different weight fractions with different sieving sizes of residues and densities. The results will show samples with higher density yields higher value of modulus of rupture, modulus of elasticity, tensile strength, Young’s modulus, screw test, impact test and internal bonding. The experimental results will also show the level of density, weight fraction, and sizes of residues affecting the performance of a board. Types of raw materials and phenol formaldehyde resin were also investigated through different tests to identify the properties of the fabricated boards. These experiments can then produce the optimal composite mixture for industrial application.
