THE EFFECT OF THE NUMBER OF FIBER SHEETS AND NAOH CONCENTRATION ON THE IMPACT STRENGTH OF ALKALI-TREATED ARTHOCARPUS ELASTICUS PEELED FIBER COMPOSITESTITLE
I will put the dimension here
Abstract
The focus of this study is the effect of NaOH alkali treatment and the number of fiber sheets on the impact strength of Artocarpus elasticus (lantung bark) fiber as a sustainable reinforcing material in natural fiber composites. However, lignin and hemicellulose can prevent the fibers from adhering to the resin. NaOH treatment improves fiber quality by removing these barriers, enhancing their mechanical properties. This study examines how differences in the number of fiber sheets and NaOH concentration affect the impact strength of the composite. The objective of this research is to determine how the number of fiber sheets, NaOH concentration, and combinations of these factors affect the impact strength of Artocarpus elasticus fiber composites subjected to impact testing. The study found that NaOH treatment significantly enhances the impact strength of lantung wood composites, with results continuing to improve. However, for the number of wood fiber sheets, the impact strength was highest after treatment with 4 wood fiber sheets. The optimal combination yielding the highest impact test results was the combination of 9% NaOH alkalization treatment with 4 fiber sheets, resulting in an impact value of 0.08 J/mm².
