Post-stress Induced Tensile Property Modification of Jute Polymer Composite

摘要

Jute fiber reinforced composites is an emerging area in composite science because of their low cost, low density and high specific properties. These composites are biodegradable and non-abrasive. In this research work, 10 and 15 wt% raw jute fiber reinforced polyester composite were made in hand lay-up method. Then each type of composite was again fabricated but this time, different levels of post-stress of 2.5, 5 and 10 kPa were applied to observe their effect. Later on, the developed composites were subjected to the tensile test. All composites had higher tensile properties (tensile strength and tensile modulus) than pure polyester. Tensile properties were observed to increase with increasing post-stress for same weight percentage of jute fiber.
