Analisa Perlakuan Alkali Dan Pengukusan Terhadap Kuat Tarik Dan Tegangan Interfacial Serat Pelepah Salak
Abstract: The aim of this
research is to investigate the alkali treatment and steaming influence on
mechanical properties of Snake Fruit frond fiber. The presence of surface
impurities and the large amount of hydroxyl groups makes natural fiber less
attractive for polymeric materials reinforcement. Effort to remove the
impurities can be done by few treatments that consist of physical, chemical,
and mechanical treatment. Snake Fruit frond single fiber were subjected to
alkali treatments with concentration and time variation and steaming. The
tensile tests was done according to standard ASTM D3379 showed the alkali and
steaming treatment resulted in different tensile strength of Snake Fruit frond
fiber compared without soaking. The highest tensile strength (353 MPa) was
found at Snake Fruit frond fiber immersed in 1% NaOH selama 30 menit. Then
treatment combinatian show the tensile strength (167 MPa) was found at Snake
Fruit frond fiber immersed in 5% of NaOH
for 30 minutes and 5 bar of steaming. Next, pull-out test with polyester resin
show that the interfacial stress reached 14,6 MPa for combination treatment of
3% alkali and steaming. These results show that the combination of alkali
treatment and steaming on Snake Fruit frond fiber effects tensile strength and
interfacial stress.
