Abstract
This study aims to evaluate the result of experimental investigation carried out on mechanical properties and dynamic mechanical analysis over a range of temperature and five different frequencies of short banana fiber polyester composite. The effect of temperature on the storage modulus (E′), loss modulus (E″), and loss factor or damping efficiency (tan δ) is determined. Composites specimen is fabricated in random fiber orientation using to hand lay-up method by Influence of fiber length (10 mm) and weight percentage (5, 10, 15, 20 wt%). Studies revealed that increase in the fiber content will increase the Mechanical property and storage modulus (E′) and the maximum is given by the composites having a fiber loading of 20 wt% at all temperature ranges. The peak height of loss modulus (E″) and damping curves (tan δ) were lowered with respect to the fiber content. The properties were compared with neat polyester. In this work increasing fiber content increases the Mechanical property and storage modulus (E′) of the composite.
