摘要：Due to its mechanical properties,cellulose is potential to be utilized as reinforcement in polypropylene composite.In this study,cellulose was extracted from oil palm frond (OPF) and distilled vetiver root (dVR) by pulping and bleaching process.Soda pulp and bleached soda pulp of OPF and dVR were analysed based on their morphology,cellulose allomorph,cellulose crystallinity,and cellulose crystal size.Polypropylene composites were produced by mixing soda pulp or bleached soda pulp of OPF or dVR (10 wt%) with polypropylene (PP) and maleic anhydride polypropylene (MAPP).The mixing was conducted in rheomix at 180°C,60 rpm for 25 min.Pulp/PP/MAPP compound was hot-pressed at 19°C,1.5 MPa for 2 min.Composite mechanical properties were tested by universal testing machine (UTM).The effect of pulp type (soda pulp and bleached soda pulp) and pulp shape (fibrillated pulp and pressed pulp) on composite mechanical properties were statistically analysed based on analysis of variance.Mechanical properties of PP/OPF composites were higher than those of PP/dVR composites.PP/OPF composite flexural strength was influenced by pulp shape,whereas PP/OPF composite tensile strength was influenced by pulp type.The flexural strength,flexural modulus,tensile strength and tensile modulus of composite PP/pressed-bleached-pulp of OPF were 22.95%,28.95%,9.28% and 56.53% higher than neat polypropylene.
