Abstract:
An experimental investigation of mechanical properties of the Low Density
Polyethylene (LDPE) and its jute fiber-reinforced polymeric composite are
presented on the basis of the results of the tensile test. Tnthis case hand injection
molding machine was used to manufacture the specimens. The long jute rope is
twisting form of many long fibers together which is called as ro\ing. At first, long
roving jute are Slraighlly set in the longitudinal direction of the mold along the
length of the specimen. Then LOPE is supplied in the form of pellets in to the
heating chamber. The LDPE is healed to form the liquid within minutes. The hot
molten LOPE is forced to inject under pressure into the cold mold through the
noz7,1c.The pressure is released after few seconds. Then the mold is setout and the
shaped specimen removed from the mold immediately. No Chemical reaction
occurs during the molting process. After that the length, \\idth and thickness of each
specimen measured with a suitable micrometer at several points. The specimen
tested under tensile load by the universal testing machine. According to the results,
it is discussed and analyzed that the mechanical properties like, max displacement,
max stress, break load, break displacement, break stress, energy absorption capacity
and young modulus arc increased in the composite material in comparison with that
of the Low Density Polyethylene resin matrix. By analyzing tor present work
further research and development, according to the needs in extension of this work.
