| dc.description.abstract | Characterization of wood plastic composites using polystyrene grafted with maleic anhydride with variations in the mass of sugar palm fiber as a filler has been successfully carried out. This research was carried out in three stages which included the alkalization process, polystyrene functionalization with Maleic Anhydride, and wood plastic composite molding. Tests carried out on PS-g-MA were determining the degree of grafting, melting point, and FT-IR analysis, PS-g-MA with a variation of 92:6 formed had an optimum grafting degree of 8,967% and a melting point of 450,15oC. Testing the physical and mechanical properties of parchment board based on SNI 8154: 2015 includes density test, moisture content test, thickness expansion test, dry flexural modulus test, flexural elastic modulus test and continued analysis of the morphology of the wood pastic composite fracture using SEM. From the results of the mechanical properties test of specimen I with the composition of sugar palm fiber: PS : PS-g-MA : BPO : DVB (70 : 40 : 30 : 2 : 3) is a wood plastic composite with optimum results, where all physical test values are in accordance with the standard composite board quality and MoR value of 218,4075 kgf/cm2, MoE 40951,406 kgf/cm2 SEM analysis shows that adding the mass of sugar palm fiber can improve the resulting physical and mechanical properties. From the results of the SEM analysis, it can be seen that there is an effect of fiber on the composite board. | en_US |
