PENGARUH FRAKSI VOLUME SERAT KAYU GELAM (MELALEUCE LEUCANDENDRA) KEKUATAN TARIK DAN IMPAK KOMPOSIT BERMATRIK POLYESTER
Abstract: The purpose of this
research is to find the effect of volume fraction variation of “gelam” bark fiber
on tensile and impact strength of polyester composite. The filler material was
the “gelam”bark fiber with volume variation ratio of 10%, 30 %, 50 % and 70 %.
Alkalization of the “gelam”bark fiber used 5% of NaOH and 2 hours of soaking
time. Mechanical testing was carried out bytensile and impact testing. The
matrix for bonding the “gelam” bark fiber was polyester resin type157 BTQN and
1% concentration of MEKPO catalyst. The mechanical properties are obtained from
tensile and impact testing: The results of tensile testing; slowed the highest
tensile strength of compositre with 70% of ‘gelam bark fiber was 15.623 MPa.
The results of impact testing: obtained the highest impact strength in
composete with 70 % percentage of ‘gelam’ bark fiber is24.772 J.
