چکیده
Purpose The impact of potassium permanganate (KMnO 4 ) treatment on the tensile strength an alkali-treated pineapple leaf fiber (PALF) reinforced with tapioca-based bio resin (cassava starch) was studied. Design/methodology/approach PALF exposed to sodium hydroxide (NaOH) in varying concentrations 2.0, 3.7, 4.5 and 5.5g prior KMnO . treated untreated PALFs were resin. Subsequently, they subjected Fourier transform infrared (FTIR) test analysis. Findings FTIR analysis revealed presence O-H stretch, N-H C=O stretch H-C-H bond. result confirmed highest 35N from that 32.5g cassava starch 1.1g In comparison, lowest 15N recorded for without treatment. Originality/value Based results, it could be deduced despite enhancement bioresin towards strength-impacting fibers, is very vital improved when compared fibers. Hence, natural fibers preceding reinforcement imperative bio-based
