The present work aims at fabrication and characterization of hybrid nano composites that could negate ecological problems and replace synthetic materials. Several material scientists around the world are focusing on materials that can be fabricated with low material cost and superior properties. However, natural fibre based composites do not exhibit excellent properties in mechanical perspective when compared with synthetic materials. Hence, in order to enhance the mechanical properties of natural fibre based composites, fillers can be added. For this reason in the present work Nano cellulose powder is added as filler to Glass fibre based composites and Jute fibre based composites.The matrix material used for composite preparation is polyester resin. Hand-layup technique is used for fabrication of composites as per ASTM Standards. Prior to sample fabrication, calculated amount of Nano Cellulose powder is mixed with polyester resin through ultra sonicator. As a part of mechanical characterization, tensile strength, flexural strength and impact strength are tested. Tensile strength increased with respect to weight percent of Nano Cellulose powder up to certain weight percent and then showed downward trend. When compared to Glass and Jute fibre based composites, the tensile strength is enhanced by 32% and 27% by the addition of Nano cellulose powder of 3% weight percent. However, tensile strength is decreased with further addition of nano powder. Flexural strength also showed similar trend as tensile strength while impact strength is increased continuously with every weight percent of nano powder. On the other hand, thermal conductivity of both the composites decreased with weight percent of nano powder and increased with increase in temperature.
