MECHANICAL BEHAVIOR OF BAGASSE FIBER REINFORCED EPOXY COMPOSITES AT LIQUID NITROGEN TEMPERATURE

摘要

The present experimental investigation deals with the mechanical behavior of bagasse fiber reinforced epoxy composites at cryogenic temperature. Bagasse fibers of 10, 15 and 20 wt % were reinforced with epoxy matrix to prepare composite. These were exposed to liquid Nitrogen temperature. Three point bend tests were carried out at a range of 2mm/min to 500mm/min cross head speed to evaluate the sensitivity of mechanical response during these loading conditions. The mechanical performances of these composites at cryogenic temperature were compared with room temperature property. These composites are found to be loading rate sensitive.
