Characterization of Carbon Fiber and Glass Fiber’s Micro and Nanostructure using Electron Microscopy, Raman Spectroscopy and XRD Analysis 2019-01-1441
Carbon Fiber and Glass fiber have different properties and different characteristics which can give the stiffer strength, lightweight, flexible behavior and high temperature resistant with high mechanical properties. Nowadays, most manufacturers are looking for improvement of lightweight parts and other components in automobile field. Carbon fiber and glass fiber are the most effective materials for their requirement to reduce the weight in vehicles. But light weight materials are not only useful in automotive field but also in marine, military and sports component due to their stiffness and flexible characteristics. The diameter of carbon fiber is 5-8μm while Glass fiber diameter is 15-18µm but they have different characteristics and properties. The diameter of carbon fiber and glass fiber are quite different but characteristics and mechanical properties are almost similar. The Mechanical strength of Carbon fiber and glass fiber are approximately 120 MPa and 110 Mpa respectively based on mechanical tensile test in fiber alone without matrix. The failure mode of both carbon fiber and glass fiber are not the same. Carbon fibers are gradually smaller in each filament due to tension force but only approximately 1.5% are elongated. As contrast, glass fiber are elongated as long as maximum machine set up parameter because its’ elongation is approximately 3%. It is almost twice tensile strain of carbon fiber. And then, electron microscopy Image processing method also shows their failure behavior and characteristic in much more detail.
