Item Study of mechanical and physical properties of LDPE-banana fiber-based composites using nano-clay as filler material(NHCE, 2024) Dilip Keshav INH20ME033 Manjunath K INH20ME069 Nanda Kishore H 1NH20ME078 Sujith paul INH20ME106The mounting concern surrounding plastic waste accumulation has spurred heightened environmental awareness, prompting a shift towards more sustainable alternatives. In this context, banana-polyethylene composites have garnered increasing attention in recent years. This study aims to assess the mechanical and physical characteristics of banana-polyethylene composites enhanced with nano clay filler. The process begins with melting polyethylene in a graphite crucible, followed by meticulous blending of banana fibers, polyethylene, and nano clay. Subsequently, the composite mixture is transferred to a die and compacted using manual pressure from a rammer. Upon solidification, the specimens are carefully removed from the die. Mechanical and physical tests are then conducted to analyze the composite's performance. These tests encompass a range of evaluations including tensile strength, flexural strength, impact resistance, density, and moisture absorption. Such comprehensive analysis provides valuable insights into the viability and potential applications of banana-polyethylene composites in addressing the challenges posed by plastic waste accumulation.Item Design and fabrication of robotic arm by using android application and material management(NHCE, 2024) Ujjwal Karthik 1NH20ME020 Shreyas D Hooli 1NH21ME415 Devaiah P P 1NH20ME032 Supreet 1NH21ME416 Dilip Keshav INH20ME033The integration of robotic technology with material handling systems has become increasingly essential in the modern industrial landscape.
