Chemical treatment of reinforcement material is one of the main ways of improving the mechanical properties of natural fiber reinforced polymer composites. In the present study, coir fiber was used as reinforcement material, while polypropylene (PP) and polyethylene (PE) polymer were used as matrix material. Before reinforcing with polymer, raw coir fiber was chemically treated with basic chromium sulfate and sodium bicarbonate in a sieve shaker. Hot‐pressed method was used for composite manufacturing during which the fiber loading was varied at 0, 5, 10, 15, and 20 wt%. Comparison of the properties of raw and chemically treated coir fiber reinforced PP and PE was conducted. Mechanical characteristics of the composites were evaluated using tensile, flexural, impact, and hardness tests. Water absorption test was conducted to know water uptake characteristics. Microstructural analysis using a scanning electron microscope was performed to observe the adhesiveness between the matrix and the fiber. Thermogravimetric analysis was done to observe the physical and chemical changes in fiber and composites. The results showed that chemical treatment improved the physical, mechanical, and thermal properties of the manufactured composites. PP composites had better properties as compared to PE composites, while higher fiber loading resulted in better mechanical properties of the resultant composites. POLYM.

Improvement and effectiveness of polymers through reinforced materials coupled with environmental nuisance of the Cissus populnea fiber remains an area of concern. Tensile responses of chemically treated C. populnea fibers were investigated. Gravimetric analysis was used to determine the composition of C. populnea fibers. Sodium hydroxide (NaOH), acetic anhydride (AC) and ethylene diaminetetra-acetic acid (EDTA), respectively, were used for fiber treatment and optimized with variable parameters (concentration and time) using response surface methodology (RSM) with central composite design. Scanning electron microscopy (SEM) with energy dispersive spectroscopy (EDS) were studied. At optimum treatment conditions, NaOH, AC and EDTA, respectively, increased the tensile strength of C. populnea fiber by 33.49, 274 and 194.52% as well as tensile modulus by 793.43, 20799.43 and 855%. Hence acetic anhydride treatment gave the best tensile properties of C. populnea fibers as corroborated by SEM with EDS. Thus, the effective use of C. populnea fiber in composite applications can be improved by chemical surface modifications.
