The need for alternate materials and the development of newer composites are increasing nowadays. The demand for specific characteristics leads to the development of the composites with various reinforcements. Reinforcements are selected based on the required properties and their field of applications. The composites need to have more resistance to wear and water absorption to use these materials under friction and underwater applications. The reinforcements added to the composite must provide hardness and wear resistance and it must repel the moisture. In this work, to acquire the required properties, the epoxy matrix is reinforced with waste plastic particulates and also filled with seashell powders. The composites are produced by mixing these reinforcements and fillers and tested for its wear and water resistance. The results showed the addition of the waste plastics and seashell powder improved the wear resistance and reduced the moisture absorption property of the composites. The results are also analyzed to study the most affecting parameter, which influences the water absorption, and wear property of the composites.
