Effect of Soaking Time in Alkali Solution on the Interfacial Shear Strength of Cantala Fiber/Recycled HDPE Composites

Abstract:

The interfacial shear strength (IFSS) between natural fibers and thermoplastics matrix is one of the key parameters to increase the mechanical properties of composites. IFSS can be improved by alkali treatment. Therefore, the research is to investigate the influence of IFSS soaking time in alkali solution of cantala fiber/Recycled High Density Polyethylene (RHDPE) composites. Experimentally, cantala fiber/RHDPE composites were manufactured by simple hot press machine. Alkali treatment on the surface of cantala fibers was carried out on 2% sodium hydroxide (NaOH) solution for a period time, i.e., 0, 4, 8, 12, 16, 20, and 24 hours. The IFSS value of composites was observed using single fiber pullout test method. The result shows that the increase of soaking time in alkali solution could improve IFSS of cantala fiber/RHDPE composites by 43%.
