Experimental Study of the Fatigue Strength of Glass fiber epoxy and Chapstan E-Glass epoxy laminates
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2013, Vol 3, Issue 5
Abstract
The present project work is aimed at establishing certain mechanical properties while designing fiber reinforced components for engineering applications. This experiment played an important role in estimation of stiffness of the laminate which in turn helps the user of the testing to evaluate the stiffness of the laminate for further mathematical purposes. The evaluating elastic properties and estimating the flexural stiffness of the composite beam and from the analytical evaluation of flexural stiffness has been matched with the theoretical calculations. This loss in stiffness of composite laminate is due to inherent defects generally occurs during welding and curing of the reinforced component. This reduction in stiffness can further be improved by advanced manufacturing process such as compressor moulding and auto clave moulding and the results obtained from the analytical testing are used to calibrate the load transducers. The load transducer shows a linear response to the load from this is clearly evident that the testing could be able to generate the useful data for evaluating the fatigue failure behavior of the composites. This data acquisition load generates the digital of time verses voltage by converting this data into time verses voltage with suitable multiplying factors. The data acquisition system from standard manufacturer of model pci-207 which exactly meets requirements. A continuous plot of time verses load could be obtained. We can say that the required data can be generated as per expectations, which could be utilized to establish the fatigue failure behavior any kind of composite laminate. (1)
