Physical Properties of Plant Fibers (Sisal, Coir) and Its Composite Material with Tamarind Seed Gum as Low-Cost Housing Material

摘要

In this study, the physical properties of sisal and coir fibers have been described. Using manual extraction procedures, the sisal fibers were extracted from the sisal plant and coir fibers from the coconut palm. Thermal analysis by differential scanning calorimetry, structural morphology by scanning electron microscopy, and the degree of sharpness of the equatorial reflections of the X-ray fiber diffraction pattern were recorded for the untreated sisal and coir fibers. Tensile strength was determined for the single fiber and the results are correlated with the tensile strength of bundle fibers. Composite material has been prepared with this plant fiber as a filler and tamarind seed gum as a matrix material. The endosperms of roasted tamarind seeds were used for the preparation of tamarind seed gum solution. The different temperature condition maintained for roasting the seeds are 130 degrees C, 160 degrees C, and 180 degrees C. The tensile strength of the prepared composite material is measured and it shows dependency of the roasting temperature condition of the tamarind seed. Scanning electron microscopy and water resistivity test were conducted, and the results were reported for the prepared composite material. Low-cost housing is made using this biodegradable sisal fiber-tamarind seed gum composite material.
