The mere presence of damping can bring back the resonant amplitudes from infinite to finite. Therefore, the damping parameter is an important parameter to be considered while designing the structures. But damping and stiffness are the two important opposing performance characteristics of the structures. Hence the development of high damping materials without affecting the stiffness is the focus of several researchers. Recently, smart materials are being introduced in polymer composites for better dynamic characteristics which enhance both stiffness and damping whenever required. In the present study, smart epoxy composites with the inclusions of austenitic phase nitinol (smart material) particle are developed and tested for mechanical and structural vibrational characteristics. Results revealed that at a weight fraction of 4% nitinol inclusion, stiffness, strength, and damping have simultaneously increased.</p> ER -
