The increasing use of advanced Ceramic Composites in Aircrafts, Automobiles, Missile Systems and Space Structures has been well documented and continuously receiving the wide attention of industry. The structural engineer needs to be familiar with the property of the composite material structures. The behavior of ceramic composite material under impact load plays a pivotal role in designing such structures. An impact test is a test for determining the energy absorbed in fracturing a test piece at high velocity. The impact resistance of a part is, in many applications, a critical measure of service life. In the current work, an attempt is made to present the dynamic behavior of the advanced ceramic composite material, i.e., 3 Dimensional Carbon-Silicon Carbide (3D C-SiC) under the impact, tensile and flexure loads and the mechanical properties, viz., Impact Strength, Tensile Strength and Flexural Strength are determined. In 3Dimensional Geometric Modeling, the spatial orientation of the yarn is explained and the geometric parameters are estimated. 3D C-SiC composite specimen with a fiber volume fraction of 40% is considered and the required mechanical properties are extracted. ANSYS software is used for structural analysis of 3D carbon-silicon carbide composites. The simulated results are checked for its feasibility.
