Abstract :

The paper highlights the results of experimental evaluation of the mechanical properties of hibiscus esculentus fibre reinforced polymer composite which were fabricated using the hand moulding process. The sample fibre was treated with various chemical solutions including alkali treatment and the tensile strength, youngs modulus and ultimate elongation for the treated sample was found to be 171.6, 1653 N/mm 2 6.5% respectively as against the values 89.49N/mm 2 , 1492N/mm 2 and 7.25% respectively for tensile strength, youngs modulus and ultimate elongation for the untreated sample. This shows that the mechanical properties of the sample are higher than that of the untreated one. This is due to the increase in fibre-matrix bond and adhersibility properties as a result of the alkali treatment. The minimum creep rates occur for polymer composite sample which has 1cm fibre length and 50% fibre volume fraction. This is due to the high fibre content of the composite sample. The statistical model of the creep rate was developed from the experimental data and the adjusted R 2 was found to be greater 0.5 as observed from table 6.0 which shows a good correlation between experimental data.
