The effect of fibre loading on characterization and mechanical properties of polyurethane foam composites derived waste cooking oil, polyol and toluene diisocyanate with adding filler sugar palm (Arenga pinnata) fibre

In the study, sugar palm (Arenga pinnata) fibre reinforced polyurethane foam was prepared by compounding waste cooking oil, polyol and toluene diisocyanate. The composites foam were prepared with different fibre loading: 10%, 20%, 30% and 40% (by weight), with the process conditions : ambient temperature, 1 min stirring and fast stirring. Four samples were cut from polyurethane foam composite and tested according to ASTM standard. Effect of fibre loading on mechanical included tensile strength, FT-IR, and SEM. From the analysis, highest condition of polyurethane foam composites tensile strength was 0.978 MPa.
