Abstract
Sugarcane bagasse fibre has many applications in the industrial sector. However, its application is limited to non-load bearing materials. Making composite of bagasse with polymers have been tested by scientists to improve strength and quality. Fibres’ physical properties like length, the diameter can have significant influence on the load transfer and load bearing capacity of the fibre as observed for other natural fibres. Although physical and mechanical properties of various composites of bagasse/ polymers have been studied, very few have been revealed about load transfer mechanism in bagasse fibre/ polymer composites. This study aims to explore the influence of fibre length on the load transfer in bagasse polyester polymer composite. Sugarcane fibres will be prepared locally. The fibres will be chemically treated with different concentrations of NaOH. The findings of the work was that addition of the fibres at optimum NaOH treatment of 6% significantly improve the tensile strength of the polyester composites. Low percent of NaOH (below 4%) is not good option since there is pull out of the fibres during the test and the fibres did not really support the matrix. Fibre length effected the strength of the composites and 15 mm fibre length found to be the critical value. Scanning Electron Microscopy observation (SEM ) showed different damages in the fibres. Pull out of fibres took place at low percent of NaOH and breakage occurred in the fibres with high NaOH concentration treatment.
