Experimental study on dynamic mechanical properties of arecanut husk fiber composite

Natural fibers gain utility value by being used as reinforcing materials in the production of lightweight and inexpensive composites. Natural fibers possess considerable mechanical properties and will replace the synthetic fiber used in applications of structural elements, such as construction materials, interior components, aerospace, automotive parts, and sports goods, packaging industries, and other industries. It is necessary to investigate the viscoelastic behavior of polymer composite over increasing temperature and frequency. The present investigation focuses on the dynamic behavior to evaluate the damping fac-tor, elastic modulus and loss modulus of AHF reinforced epoxy composite using a DMA Q800 instrument in double cantilever mode at heating rate of 3 degrees C per minute over ramping temperature from 28 degrees C to 125 degrees C with multi-frequency ranging from 1 to 10 Hz. The dynamic characteristics of AHF reinforced epoxy composites are impacted by frequency and temperature. The modulus values increased as the loading frequency increased, and the modulus values decreased as the temperature increased. Glass tran-sition temperature was increased from 84 degrees C for untreated AHF composites to 91 degrees C for treated AHF com-posites. Treated AHF composites show improved storage and loss modulus compared to untreated AHF composites because of 6 % KOH treatment of AHF.Copyright (c) 2022 Elsevier Ltd.
