Mechanical and water-absorption properties of composites made from sisal fiber and polyester matrix have been investigated. Test specimens were prepared with untreated fiber and treated with alkaline solution of sodium hydroxide. The amount of fiber content in the composites varied with values of 10%, 20%, and 30% by volume. The test results indicate that the alkaline treatment has improved the tensile, compressive, and impact strength of the composite with the added benefit of low water absorption. The impact strength is found to increase with an increase in the fiber content. However, the tensile and compressive strengths have decreased; water-absorption rate has increased with an increase in the fiber content.
