Tensile Behaviour of Nanoparticle Reinforced Epoxy-Polyurethane Composite Water Pipeline

Abstract:

Abstract. The pipelines for offshore water applications are made of Polyurethane (PU) or polyurethane coated. Most of the shape memory polymer composites are made with polyurethane resin, which has poor mechanical properties. Thus it is blend with epoxy resin (EP), because epoxy resin has got good mechanical properties. So designing a suitable composite for shape memory application with improved mechanical properties has become important as it can be used in offshore pipelines for several years. Since epoxy resin has got good mechanical properties, the hardness of the Nanocomposite composed of the heat treated clay powder dramatically increased as a function of clay content, which is attributed to the homogeneous dispersion of the Nano fillers in the polymer matrix and strong filler–polymer interactions. Mechanical properties of the attapulgite clay reinforced polyurethane shape-memory Nanocomposite are strongly dependent on the pre-treatment of the Nano-powders.The energy consumption for actuation and ability to remember two or multiple shapes and the knowledge of the glass transition temperature are very important for the characterization of the composite materials. In this work, the developed composite material is compared with a existing polyurethane composite with the help of Tensile test. It has been observed that the developed composite material strength increases abruptly compared to pipelines made of polyurethane.
