“…Polymers and their composites are being increasingly employed in view of their good strengths and low densities. Besides, a wider choice of materials and ease of manufacturing make them ideal for engineering applications [1,2]. Kevlar aramid [poly(p-phenylene terephthalamide); PPTA] fiber is widely used in the manufacture of advanced composites, owing to its high strength, high modulus, toughness, and thermal stability [3,4].…”

RETRACTED: The Effect of Kevlar Pulp Content on Mechanical and Tribological Properties of Thermoplastic Polyimide Composites

Different contents of Kevlar pulps were employed as reinforcement for polyimide (PI) composite. All filled and unfilled polyimide composites were tested against CGr15 ball and representative testing was performed. The effects of Kevlar pulps content on tribological properties of the PI composites were investigated. The worn surface morphologies of neat PI and its composites were examined by scanning electron microscopy (SEM) and the wear mechanisms were discussed. Results show that all the filled polyimides have superior tribological characteristics compared to the unfilled ones. The optimum wear reduction was obtained when the content of Kevlar pulps is 15 vol%.

The concept of using piezoelectric materials with structural elements is to monitor the behavior of the structure when it is subjected to a load. This paper describes a kind of self repairing structures by integrating the piezoelectric patch with laminated composite plate. The coupled character of mechanical and electrical behavior of piezoelectric material will be used to sense the deformation in the material and actuate it to resist the deformation when subjected to a load. The fatigue behavior of the laminated composite plate is studied for the cyclic bending load by experiment. Mathematical simulation is carried out using finite element method. The test specimen is prepared from a glass/epoxy laminated composite plate. The laminate is constructed as cross-ply with 50:50 fiber/matrix. The alternating stresses are derived from the tensile and three point flexure tests. The fatigue behavior is studied for the constant amplitude displacement at three different stress levels. Based on the fatigue characteristics observed from the experiments, the laminate without and with piezoelectric patch are simulated using finite element method. The simulation results for laminated composite plate with piezoelectric patch has shown a considerable increase in the fatigue life cycles. CITATION: M. Sundaravadivel and R. Dhanaraj. 2010.
