Impact Strength, Water Absorption and Chemical Resistance of Untreated and Treated Cordia-Dichotoma Fiber/Polyester Composite

Abstract

The effects of alkali treatment on the impact strength, water absorption, and chemical resistance properties of Cordial-Dichotoma natural fiber/polyester composites, were studied. Alkali treatment (5% NaOH) was used to improve the interfacial bonding between the matrix and the reinforcement. The composites were fabricated using hand lay-up
