Composite materials are highly suitable to withstand with mechanical loads compared to conventional materials. At present, these materials are being substituted with composite materials due to their superior properties and broadly used in aerospace industries and other industries. In this work, investigations are conducted out to determine the mechanical properties of composite laminates, for various orientations (0°/30°/45°/60°) of kevlar fibres with glass fibres. The different mechanical testing such as tensile test, flexural test and dynamic Mechanical Properties of the hybrid composite material with various orientations of the top and bottom Kevlar laminates were evaluated. It is concluded that the Fabricated hybrid composites with 0° orientation of the Kevlar fibres exhibit higher tensile Strength as well as flexural strength compared to the composites with oriented kevlar fibres (30°/45°/60°). The increased mechanical properties of the 0° hybrid is due the alignment of the kevlar fibres in loading direction which causes it to act as the primary load bearing structure whereas in the oriented hybrid composites the glass fibre acts as the initial load bearing structure.
