Abstract :
Because of the nature of natural fibers that can be recycled or recycled in
other renewable conditions, it has features heat insulation, corrosion resistance,
and current-resistant and also environmentally friendly in addition to the
application of composites that are very wide ranging from household, land
vehicles, ships to aircraft and UAV. This study aims to determine the strength of
the Hybrid composite tensile test of hemp fiber and banana stems with volume
fraction variations of 30%, 40% and 50%. To determine the value of composite
tensile strength, tensile testing is needed using the Qualitest brand Universal
Testing Machine with a load cell capacity of 5 tons at the Nurtanio laboratory of
the Adisujipto Institute of Aerospace Technology Yogyakarta. Starting from
composite manufacturing with the hand layup method using epoxy resin and
volume fraction variations of 30%, 40% and 50%. From the results of tensile
testing of composite specimens, analysis and comparison were obtained that the
volume fraction was 50% stronger in tensile strength, which was obtained at an
average value of 136,887 MPa than 30% which was at 71,263 Mpa. Inconclusion
that the higher the value of the fiber volume fraction, the higher the value of
tensile strength beside other influencing factors.
