Abstract
A poor bonding e resin and natural fiver is a problem in green composites. In order to make better composites, which have good bonding between resin and fiver, surface treatment methods by using such as NaOH solution have been proposed. In this study, unidirectional composite laminate which consists of PLA and kenaf string treated by NaOH solution was molded, and the effects of surface treatment on mechanical properties such as bending strength and transverse tensile strength were evaluated.
