Continuous Wavelet Transform on Diesel Engine Vibration Condition Monitoring

In this study, composites were prepared by reinforcing thermoset epoxy with different weight percentage (0, 10 and 20 wt%) of ceramic filler (Potassium Titanate Whisker, PTW) using casting method. The basic mechanical properties of test samples were evaluated as per ASTM standards and it was observed that except the strength all properties were found to improve with the PTW addition. The thermomechanical properties of the samples were investigated by Dynamic Mechanical Analysis (DMA) over a temperature range of 25° C to 125° C. Storage modulus and loss modulus of the Epoxy/PTW composite samples exhibited considerable improvement over the initial temperature range. However, damping (tan δ) peaks of composites were lowered by addition of PTW filler. The study indicated that incorporation of PTW in Epoxy could effectively improve the thermomechanical properties of composites.
