Thermophysical and Mechanical Behaviour of Nanosized Periwinkle Shell Ash Reinforced Low-density Polyethylene Composite: Long-term Salt-water Aging Influence
Subject area: Science,Engineering and Technology · Area of research: Environmental Engineering
Abstract
The utilization of marine and agricultural waste into a more useful and promising alternatives to conventional materials commonly used for construction, fabrication and insulation in the civil engineering industry, Oil & Gas industry, maritime industry etc. This experimental investigation of the thermal and mechanical characteristics of periwinkle shell nanoparticle and low-density polyethylene to come up with a new novel material with predictable thermophysical properties that will be able to with some terrain with specific chemical composition. Three samples k1, k2 and k3 were collected, exposed and fabricated by thermoforming their homogenous mixture at a very high temperature with the following composite - polymer percentage composition of 15% periwinkle shell nanoparticle and 85% polyethylene, 25% periwinkle shell nanoparticle and 75% polyethylene, and 35% periwinkle shell nanoparticle and 65% polyethylene, in order to ascertain the impact of increasing concentration of periwinkle shell nanoparticle on the characteristics of reinforced composite. All samples were tested for thermal conductivity, friction wearing, water absorption and long-term acid aging. Thermal conductivity of the reinforced composite increases as the percentage of concentration of the periwinkle shell nanoparticle increases of the polyethylene in the composite. As concentration of the periwinkle shell nanoparticle increases over the polyethylene in the composite, the frictional wear coefficient of the composite decreases. Also, the rate at which water is absorbed by various samples of the composite decreases as the concentration of periwinkle shell nanoparticle increases in the reinforced composite.
