Many of our modern technology require materials with unusual combination of properties that cannot be met by the conventional metal like alloys, ceramics and polymeric materials. This requirement is fulfilled by using composites. However, there is still research being done to improve this class of materials' mechanical properties. Due of their significant impact in the defence and aerospace industries, researchers from all over the world are focusing their research on creating new, superior hybrid materials. The mechanical and thermal properties of hybrid composites are expected to be superior to conventional materials and also the base materials from which they are developed from. Due to the complexity of their natural architecture, much research is needed before these materials may be used in any application. The present research work is focused on the prediction of the mechanical properties of the hybrid composites where continuous kevalr49 fibers are reinforced in a micro graphene nanoplatelet particles embedded epoxy matrix applicable in designing of structural of engineering systems. Finite Element Analysis was used to predict the mechanical properties of the new material using Abaqus. The predicted elastic properties from FEM are compared with analytical results by varying different volume fractions of graphene nanoplatelets in epoxy and by varying volume fraction of Kevlar49 fiber.
