The natural fiber composites based on kapok/sisal and its hybrid composites with polyester as resin matrix have been prepared and tested for mechanical properties. In this paper hardness and flexural properties of kapok/sisal composites were determined with reference to the fabrics content and varying the volume ratios of fabrics. The maximum strength in the properties determined is observed for the optimum fabric loadings. The effect of alkali treatment of fabrics on polyester composites reinforced with kapok/sisal fabrics was studied. Increasing the sisal fiber content resulted in a reduction in the hardness and flexural properties. The properties were found to increase with alkali treated fabrics used in composite. The properties of kapok/polyester composites are found to be better than those of kapok/sisal polyester composites.
