Keywords:
XRD, SEM, FTIR, TGA, DTA, Calotropis GiganteaAbstract
The present investigation is focused on the characterization of fibers, Alkaline treatment of fibers, fabrication of Calotropis Gigantea-Epoxy composites and evaluation of tensile, flexural, impact, hardness, water absorption and wear behaviours. The presence of various organic materials in Calotropis Gigantea fiber was identified by using X-ray diffraction technique. The chemical structure of various groups and bonds in untreated and treated fibers were identified using Fourier Transforms Infrared spectroscopy. The thermal behaviors such as weight loss due to temperature and melting point were identified for the fiber and epoxy resin using Thermogravimetry Analyzer/Differential Thermal Analyzer. The tensile properties of raw and treated king crown fibers were evaluated using Instron Universal Testing Machine as per ASTM D638. The composite fabrications were planned as per design of experiments method using full factorial design. The fabrication parameters such as fiber length in three levels and fiber volume in six levels were selected and 18 composites were fabricated.
