Abstract: Composite materials are a better replacement for conventional materials due to their acceptable mechanical properties. Notable characteristics of composites play an important role in automobile applications like a bumper beams in passenger cars. The paper was developed to fabricate a silk/sisal hybrid natural fibre composite material that can replace the conventional composite material. Both silk and sisal fibre was woven together using a traditional weaving machine. Four samples of composites are fabricated in which one sample is fabricated without filler material and the other three samples of the composite are fabricated by changing the volume percentage of filler material by 2%, 4%, and 6%. The hand layup method was followed for making the composite. The fabricated composites are evaluated for their properties, viz., tensile, flexural, and impact strength, and also the free vibrational behaviour of the composite.

Keywords: natural fibre; granite filler; mechanical properties; modal damping.
