Fibre loading effects on dynamic mechanical properties of compression moulded luffa fibre polyester composites

Abstract

In this work, dynamic mechanical analysis (DMA) of untreated luffa fibre composites has been carried out. Composites are produced using luffa fibre mat and polyester resin. Compression moulding is done at 5MPa pressure from 30 to 50% for varying fibre loading. Temperature ramped dynamic mechanical analysis is done to understand the fibre loading effects on dynamic properties. Results show, that increase in fibre loading significantly increase the storage modulus of the composites without any change in mechanical characteristics. Cole-Cole plot is drawn to understand the elastic-plastic behaviours and results reveal that, the more fibre is mixed content the more the elastic behaviour is found.
