Abstract

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 matrix composite material, i.e., 3 Dimensional Carbon-Silicon Carbide (C-SiC) under the impact, flexure, tensile loads and the mechanical properties, viz., Impact Strength, Flexural Strength and Tensile Strength are determined. In 3 Dimensional Geometric modeling, the spatial orientation of the yarn is explained and the geometric parameters are estimated. 3D C-SiC composite specimens with a fiber volume fraction of 40% are prepared by Liquid Silicon Infiltration (LSI) process to conduct the required experiments for evaluating the mechanical properties. The experimental results of impact, flexure, shear and tensile strengths recorded during the tests are 26.82kJ/m2, 230.3MPa, 30.5 MPa and 70.2MPa respectively. Computer simulations by using ANSYS 11.0 software gave consistent results with a variation of appr.1- 4% which can be considered as an acceptable range.
