Abstract:
Natural fibers from Plants and Animals have a major role in developing ‘green’ economy.
Because it has attractive features of abundant availability, renewable resources, environmentally
friendly, high specific strength, non- corrosive, low cost and biodegradability. Most of these
natural fibers are discarded in to land fill areas as wastes and removed by open burning that
may lead to air pollution. Need of Structural material which are efficient and effective are vital
issue for researchers. The present study focus on using of natural fibers like sheep wool and
Sisal fiber for manufacturing the hybrid fiber composite (HFC) for structural application. This
HFCM was synthesized by hand lay-up technique with design consideration of principal
parameters like fiber orientation, fiber volume ratio, and ply arrangement. Then, mechanical
tests and physical tests were conducted to characterize experimentally. Those fibers surface bind
together by using polyester. In this work both theoretical and experimental studies were
performed. The effects of fiber orientation, ply arrangement and fiber volume ratio on
mechanical properties of the HFCM were studied. The results showed that increasing fiber
content above optimum limit decreased the strength of the composite. In addition to that,
concentrating Sisal fiber was preferable to enhance the strength of HFCM than concentrating
wool fiber. Chopped orientation of the fiber also shows better strength than the other. SWS ply
arrangement for the mat one and CSW-20% fiber volume ratio for chopped type is optimum
model with 20.16 MPa and 50.22 MPa tensile strength and 127.01 MPa and 242.5 MPa modulus
of elasticity respectively
