STUDI SIFAT MEKANIK KOMPOSIT SERAT SANSEVIERIA CYLINDRICA DENGAN VARIASI FRAKSI VOLUME BERMATRIK POLYESTER
Abstract: This study aims to
create and analyze the tensile strength of the material matrix composite
reinforced polyester resin natural fiber Sansevieria cylindrica leaves that
will eventually be in seek of new composite materials which might be expected
to be a reference material that is environmentally friendly. The results showed
an increase in tensile strength of the composite fiber volume fraction of each
additional up to 20%. At 10% fiber volume fraction values obtained 18.459N/mm2,
then power up the volume fraction of 20% to reach a value 45.698N/mm2, but declining
power back on composite with 30% fiber volume fraction is 32.891N/mm2. From
microstructure observations made by SEM photo can be seen in the composite
fiber distribution uneven in some parts of the composite fiber reinforcing
material contained gaps, so that part hasthe tensile strength values are
different.
