	Abstract

The hybrid composites of coir/silk unsaturated polyester-based hybrid composites with different fiber lengths were prepared. Coir–silk fibers are taken in the ratio of 1 : 1, and these fibers are incorporated with unsaturated polyester resin with different fiber lengths like 1, 2, and 3 cm. The variation of mechanical properties such as tensile strength, flexural strength, and compressive strength of these composites with different fiber lengths has been studied. In the present work hand lay-up method was used for making the composites. Coir fibers are treated with NaOH and the effect of alkali treatment on the tensile, flexural, and compressive properties of the coir/silk hybrid composites has also been studied. Significant improvement in tensile, flexural, and compressive strengths of the coir/silk hybrid composites has been observed by these treatments.
