Influence of varied Environmental Conditions on Tensile and Damping Behavior of Glass-Cotton Composite laminates

Abstract

Composite materials are used in differing applications running from aviation to sports equipment and other domestic applications. The mechanical and environmental behavior of these composites are important to additionally improve their utilization area. The mechanical characteristics of polymer matrix composites in specifically is influenced by the environmental conditions. The goal of the present study is to depict the tensile nature of the glass-cotton hybrid polymer composites when exposed to normal water, seawater, kerosene, and NaOH conditions with two different exposure times. The damping characteristics of the glass-cotton hybrid polymer composite have also been investigated. Experimental results confirmed that the maximum reduction of 25.39% in tensile strength was associated with the specimens of volume fraction 25:25 immersed for 10 days in NaOH solution and minimum reduction of 1.3% in tensile strength was associated with specimens of volume fraction 25:25 immersed for 10 days in normal water. Damping is the property that measures the energy loss of the material subjected to cyclic strain and it is measured by dynamic mechanical analyser. The lowest glass transition temperature for volume fraction of 30:20 was found to be 75⁰C
