Hybridization process is one of the best ways to improve the materials properties. In this work, we prepared five different composites by using the same matrix materials. Composites were fabricated on the basis of the rule of hybridization (0.4Wf) mixtures. The materials used for this test were Hemp, Flax fibers and epoxy resin along with hardener was used as a reinforcement material. The fabricated composites were taken to the material testing to investigate the properties and comparison purpose. Three tests were conducted to examine the properties such as Contact angle measurement, Flexural test, interlaminar shear test. These tests were done on the basis of ASTM standards. The results showed that enhanced properties and hybrid composites showed improved flexural strength and interlaminar shear strength results when compared to the pure composites.
