Effect of Graphene Filler on the Mechanical, Electrical, and Thermal Properties of Polymer Composite
Composite materials with organic matrices, such as carbon fiber-reinforced polymer (CFRP) and glass fiber reinforced polymer (GFRP), are increasingly being employed in multiple industrial sectors, such as aeronautic, marine, submarine, wind energy, and road vehicles. In general, the fiber-reinforced polymer...
Transmission of electric energy The main objective of the power system is to provide electrical energy from power source to the consumers in a safe and reliable way at the lowest possible cost . The bulk movement of electrical energy...
With the aim of reducing the fuel emission, the aviation industry is developing a new generation of structures by the motivation of decreasing fuel consumption. As a result, new materials are used to build new ultra-high resistance airframes and components....
Multifunctional materials for EMI shielding Polymer composites and blends An extensive class of materials is used for EMI shielding purposes. Metals are by far the most used materials, however, with the development of more sophisticated electronic technology, metals are being...
POLYMER BLENDS & THEIR RHEOLOGICAL BEHAVIOR This literature review covers generalities about immiscible polymer blends, the compatibilization using block copolymers or nanoparticles and the use of shear and extensional rheology to characterize polymer blends behavior. Polymer blends: Generalities The final...
MEMS Technology MEMS is the technology of microscopic devices. At the nanoscale, it merges into Nanoelectromechanical systems (NEMS). MEMS are also sometimes referred to as microdevices or micro-systems technology. MEMS are made up of components that range in size between...
Today, both diagnostic and treatment of vascular diseases remain challenging. These diseases include the well-known stenosis of blood vessels due to atherosclerosis but also localized dilatation of arteries (called aneurysms) (Moxon et al., 2010), abnormal connection between arteries and veins...
Structure Cellulose is a linear, high molecular weight polymer built up from P-D-glucose units that are linked via P(1,4) bonds and belongs to the chemical group of poly saccharides. Cellulose of natural origin is organised in strongly bound bundles of...
In recent times, the polymer or plastic materials have seen a rapid growth in replacing the conventional metallic piping structures, mainly due to their economical production cost and minimal dependence and impact on the environment. The typical advantages of polymers...
