Abstract: The aim of this research is to study the hardness on varying oven temperature for acetic anhydride concentration in raffia palm fibre. Raffia palm is a natural fibre with their long history of serving mankind, are very important in a wide range of applications, and they compete and co-exist in the twenty-first century with man-made fibres, especially as far as quality, sustainability and economy of production are concerned. The matured raffia palm fibre was cut, gathered, extracted, retted, dried, treated and modified. The fibres were thoroughly washed to neutrality and oven-dried at various temperatures at different fibre length for the modified fibre. After the fibre was dried, the mercerized fibre was treated with acetic anhydride solution at 5% with soaking time of 60 minutes (1 hour) at three acetylation temperatures of 30° C, 50° C, and 70° C with varying fibre length of 50 mm, 60 mm, 70 mm and 80 mm. The results of hardness test conducted on the 5% Acetic Anhydride concentration for three oven drying temperature using different fibre length for modified fibre, shows the optimum hardness of 370 HB at 60 mm fibre length using 50° C oven drying temperature. While at 277 HB also showed reasonable hardness at 70° C using 60 mm fibre length and 185 HB at oven drying temperature of 30° C using 80 mm fibre length. Therefore, the hardness of 370 HB at 60 mm fibre length using 50° C oven drying temperature gave the highest value and the research benchmark. The result shows increase in hardness with treatment of fibre. Usually, modified fibre specimens possess higher hardness. Incessantly, these brittle and hard fibres will oppose deformation due to indentation. Natural fiber composites have gained increase value in the production of oil and gas, offshore, onshore facilities like pipes and piping system and pressure vessel.
