Combining two types of fibers may aid in improving the fundamental properties of organic fiber-reinforced hybrid polymeric materials. Biomaterials created from raw materials are gaining appeal in the industrial sector due to their high quality, as well as sustainability and environmental considerations. Natural fiber-reinforced hybrid nanocomposites were created in this work using a compression moulding technique with wood particles, hemp fiber, polypropylene, and montmorillonite nanoclay. Following that, the impacts of fiber mixture and vermiculite on mechanical and compostable qualities were studied. Both the coir and the hemp fibers were alkali-treated to minimize their hydrophilic nature before even being employed. Using universal tensile testing equipment, the mechanical characteristics of the prepared composites were investigated and found to be improved following fiber blending and nanoparticle inclusion. The maximum strength was occurred at the combinations like 10 wt. % of wood particle, hemp, nanoclay, and 70% of polypropylene matrix. Scanning electron microscopy showed that nanoclay significantly increased the adherence and interoperability between fiber and the polymer matrices. The good biocompatibility and water absorption capabilities of the nanocomposite were increased by mixing fibers, but nanoparticle additions seemed to have the opposite impact.

Fin tube heat exchangers are used in many heating and cooling devices for the purpose of heat transfer from one element to other by conduction and convection. Due to their designs fin tube heat exchangers also provide a control space or volume for carrying out chemical reactions by extracting heat from the surrounding or liberating heat to the surrounding while undergoing an endothermic or exothermic reaction respectively. The Thermally Activated Cooling (TAC) system developed by Thermax Ltd. is a device one of its kind. It comprises of metallic powder which undergoes endothermic and exothermic reactions at different temperature. When arranged in a proper cycle desired cooling effect can be obtained via this process, The fin tube heat exchangers comprise of metallic powder and provide a control volume for reactions and a conductive surface for heat transfer. The amount of metallic powder in the heat exchanger is proportional to its performance, which is directly proportional to the COP of refrigeration system. The agenda of this project is to enhance the material filling process which is a crucial stage and requires a lot of time.
