EXPERIMENTAL INVESTIGATION OF MECHANICAL AND DYNAMIC CHARACTERISTICS OF HYBRID NATURAL FIBER COMPOSITE
Main Article Content
Abstract
From decades, natural fibersin the form of reinforcements in polymer composites havebeen a test subject for scientistsbecause of its growing familiarity wide range of applications. Banana(B)andSisal(S)fibers arein good potential as reinforcement is polymer composite.The hybridisation ofshortBanana and Sisal fibers producesgood properties compared to only Banana fiber.In this present work, an experimental study has been conducted to determinethe effect ofonly banana fiber and effect of volume fraction namely B-S 20-20%, B-S 30-10% and B-S 10-30% on vibrational analysisparameterssuch as Natural frequency, damping ratio and mode shapesof Banana and Sisal fibers reinforced with epoxy resin Lapox L-12using FFT analyzer.The nodes created on the test specimen is hit by an impact hammer causes the vibration which is detected by the sensor and converted in to V,I signal through transducer.
