Abstract

Fibre is one of the elements that have been used as reinforcement material to produce composites. This fibre usually present in the filament phase which having an extraordinary mechanical feature in term of strength and stiffness of properties. Coconut fibre can be classified as one of the natural fibre which is a part of fruit fibres. In order to reduce the agriculture waste, coconut fibre is used to replace other material in the industrial production field. A Large quantity of this waste, if not properly disposed of, can cause to environmental pollution. This experimental investigates on coconut fibre composition profiling with respect to the modulus of rigidity. Furthermore, the purpose of this study was to develop new composite with the addition of biodegradable waste. Then, this research was tested and compared the new develop composite in order to obtain the best in range value of modulus of rigidity between long and short fibre. The mold of the sample has been fabricated based on ASTM E143. The effect of the fabricated mold of the sample has been detected by using the solid work simulation. In order to get the modulus of rigidity, torsion experiment was conducted by using torsion testing machine. Based on the result and discussion, 40% of long coconut fibre reinforced with polyester resin and 25% of short coconut fibre reinforced with polyester resin gave the best in the range of the modulus of rigidity in this research compared to the others percentage. Based on the result of the modulus of rigidity that obtained from the testing show that long fibre is the best result compared to the short fibre. The long coconut fibre was more elasticity and has a good strength than the short coconut fibre. The long coconut fibre gives the higher performance and good mechanical properties towards the polyester resin.
