Physico-chemical and thermal properties of untreated and treated Acacia planifrons bark fibers for composite reinforcement

In this work, the effects of alkali treatment on the chemical composition and thermal decomposition of Acacia planifrons fibers were investigated. The fibers originating from the bark of an Acacia planifrons tree were alkali treated with various concentrations (2% and 5% w/v) for 30 min. The treatment was found to diminish the amorphous contents, improve the crystallinity index and thermal stability of the fiber. The crystallinity index of the...
