Pengaruh Perlakuan NaOh dan Rendaman Air Tawar terhadap Kekuatan Bending Komposit Serat Limbah Rambut Manusia

Abstract

This study was conducted to determine the effect of NaOH treatment and immersion on the bending strength of human hair waste fiber composites. 30% fiber volume fraction, NaOH treatment used is 5% while immersion used is immersion in fresh water and sea water. Analysis of data from bending tests using the ASTM D7264 standard. The results of tests that have been carried out on composites treated with NaOH without using immersion produce a higher bending stress which is 0.245 Mpa compared to the composite without NaOH treatment with the type of seawater soaking that is 0.125 Mpa. The bending moment on the type of NaOH treatment without using immersion has the highest bending moment value of 8.52 Nmm, while the type of treatment without NaOH with seawater immersion has the lowest bending moment value of 4.36 Nmm. The highest deflection occurs in specimens with the type of treatment without NaOH with fresh water immersion which is 8.81 mm, while the lowest deflection occurs in specimens with the type of NaOH treatment without immersion is 6.06 mm
