Wettability Properties of Coconut Fiber on Resin

Imran Musanif | Artian Sirun ^[2] | Silvy D. Boedi

Abstract: This research investigates the effect of alkali treatment on the ability of wettability in cocout fiber composites to measure contact angle, resin Polyester is dripped on untreated fiber (green fiber) and fiber that has been soaked in 3 % NaOH solution for 1, 2, and 3 hours. After drying, the matrix droplet on the fiber is observed with a microscope equipped with software for analysis. Substantially, contact angle the value will be smaller after alkalization so the quality of the bond will increase, because the surface of the fiber becomes coarser and porous and the loss of the lignin layer and other impurities. With the increasing of the bonding quality between fibers and matrices, it is believed that the strength of coco-polyester fiber composites will increase compared to fibers without alkali treatment.
