The today’s research trend in composite is for the development of composite with natural fibre instead of
synthetic fibre. It is because of properties like light weight, low cost, bio-degradability, low environmental impact and ease to
manufacture. It becomes necessary to study the vibrational behaviour of composite in addition to mechanical strength and
chemical properties for effective utilization in real world applications as they subjected to many types of loading condition
and different types of vibration with different configurations. In present work a natural fibre composite beam is manufactured
with unidirectional and bidirectional orientation for measurement of transverse vibration with different end configurations.
Results are obtained from analytical method and analysis through ANN are compared. The mechanical properties are
considered by performing tensile and flexural strength of the beam according to ASTM standards. Jute (bidirectional and
unidirectional) and sisal (unidirectional) fiber are taken as fiber component and unsaturated polyester resin / Epoxy is as
matrix material.
