Effect of jute and kapok fibers on properties of thermoplastic cassava starch composites
چکیده انگلیسی

Since mechanical properties and water uptake of biodegradable thermoplastic cassava starch (TPCS) was still the main disadvantages for many applications. The TPCS matrix was, therefore, reinforced by two types of cellulosic fibers, i.e. jute or kapok fibers; classified as the low and high oil absorbency characteristics, respectively. The TPCS, plasticized by glycerol, was compounded by internal mixer and shaped by compression molding machine. It was found that water absorption of the TPCS/jute fiber and TPCS/kapok fiber composites was clearly reduced by the addition of the cellulosic fibers. Moreover, stress at maximum load and Young’s modulus of the composites increased significantly by the incorporation of both jute and kapok fibers. Thermal degradation temperature, determined from thermogravimetric analysis (TGA), of the TPCS matrix increased by the addition of jute fibers; however, thermal degradation temperature decreased by the addition of kapok fibers. Functional group analysis and morphology of the TPCS/jute fiber and TPCS/kapok fiber composites were also examined using Fourier Transform Infrared Spectroscopy (FTIR) and Scanning Electron Microscopy (SEM) techniques.


► TPCS matrix was reinforced by the low (jute) and high (kapok) absorbency cellulosic fibers.
► Water absorption of the TPCS/jute and TPCS/kapok fiber composites decreases.
► Stress and Young’s modulus of the TPCS/jute and TPCS/kapok fiber composites increase.
► Thermal degradation temperature of the TPCS/kapok fiber composite decreases.
