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 by tensile and impact testing. The matrix for bonding the “gelam” bark fiber was polyester resin type 157 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.
