IMPRESSION CREEP BEHAVIOUR OF ALUMINIUM (7079)-BASED CARBON FIBRE REINFORCED METAL MATRIX COMPOSITES PERFORMANCE OF QUANTUM DOT BASED INTERMEDIATE BAND SOLAR CELLS

Abstract

The objective of the current study is to evaluate the impression creep behavior of Aluminum-based Carbon Fiber reinforced Metal Matrix Composites for three different temperatures, namely, room temperature, 100oC, and 200oC, while applying a constant load of 2 kg, and to find the steady-state creep rates as well as the creep mechanism that is taking place. In this specific test, a cylindrical indenter that has a flat end is used to make a shallow imprint on the surface of the specimen". This imprint is then examined. This imprint is created on the specimen as it is being stressed, and the tension is what gives it its shape. In order to produce an impression creep curve, the penetration depth at a certain tension is measured as a function of time. This is done so that an impression creep curve may be produced. When the load is held constant, it may be possible to identify a link between the normal creep curve and the impression creep curve. Both of these creep curves show deformation over time. The method is done out a number of times, with the temperature being altered in a new way for each iteration. Examining the imprint creep curve is one way to gain an understanding of the creep qualities possessed by the specimens. Under the context of this examination, the specimens stand in for four separate classes of carbon. For the course of one minute and thirty seconds, readings of the deflection are recorded. A plot of an impression creep curve is going to be done so that the creep behavior may be determined.
