In
this paper experimental work on Jute/ epoxy
composite curved beam subjected to
four point bending has been
carried out. Two, Four, six and eight layers of
woven fabric jute/ epoxy
composite curved I-beams were fabricated by hand
lay-up moulding fabrication process. The test specimen is a continuous Curved
I-beam consisting of a central circular 90o region connected by two 200 mm straight legs. The load-displacement
response was
obtained and the energy absorption values were calculated for all
the composite curved I-beams. Glass/ epoxy composite curved beams were also
fabricated and tested for comparison purpose. The woven fabric composite curved
beams mechanical properties have been obtained from tensile tests. Results from
this investigation show that the bending load required for jute/epoxy composite
curved I-beams under four point bending was less 21% than glass/ epoxy. The
first crushing loads difference between jute and glass/ epoxy fell in the range
of 19%-24%. It has be en found that the failure mechanism of jute/ epoxy
specimens is similar to that of glass/ epoxy. Specimens failed after the
initial crushing load localized at the lower part of the beam center region. Then,
it followed by the matrix and fiber break. Delamination was also occurred on
both materials tested.
