Carbon nanotubes as Reinforcement Material for Tyre Rubber and Automobile Components
Carbon nanotubes are one of the most researched nanomaterials because of their excellent mechanical, electrical and thermal properties. It consists of carbon atoms covalently bonded in a cylindrical crystalline lattice. A single wall carbon nanotube consists one cylinder of carbon atoms while multiwall carbon nanotubes have many concentric cylindrical lattices of carbon atoms. Single walled carbon nanotubes (SWCNTs) are much lighter yet many times stronger than steel making them the strongest known material. The Young’s modulus of SWCNTs is in order of 1 TPa, where as carbon fibers have 800 GPa and glass fibers have 70 GPa.
CNTs have average breaking strength of 30 GPA whereas carbon fiber about 6 GPa and high strength steel about 3 GPa. The main challenge for CNTs is to effectively disperse them in polymer and rubber matrices. The main objective of best university in Jaipur, JKLU research is to use innovative ways to improve the dispersion of carbon nanotubes in rubber and other viscous polymer matrices.
Nanotechnology applications in automobile and tyre Industry
Carbon nanotube based polymer composites are many times stronger and yet lighter in weight than steel and replacing the metals in the aircraft’s structures and thus reducing the fuel consumption. Carbon nanotube based coatings and paints are finding use in radar absorbing materials as well as to help airplanes avoid accidents due to the lightning strike. Carbon nnaotubes are one billionth of meter in diameter. Our hair is 70,000 times thicker than a carbon nanotube which is an amazingly powerful material having excellent electrical, mechanical and thermal properties.
CNT based polymer composites are finding applications to make various components of an automobile car including but not limited to: headlight mirror coatings, side trims, door inners, body panels, engine cover, inverter cover, timing belt cover and tyres. Carbon nanotubes based composites are finding use in high performance tyres with less weight and better fuel efficiency, better durability and having higher grip to the road than traditional carbon black based tyres.
Nanotechnology polymer and rubber testing laboratory at JK Lakshmipat University
Since, JKLU is being supported by well-known JK Group of Industries that is the leader in variety of commodity sectors such as cement, paper, tyre, defense electronics, dairy and agriculture seeds, the emphasis at JKLU is therefore always remains on the industrial application of the technical education. In view of this, the research efforts being carried out by the Principal Investigator, Dr. Murari Lal Gupta include to set up a rubber and polymer characterization laboratory with the help of JK Tyre and industries Ltd. Proposal for funding is being submitted to the Department of Science and Technology, Government of India for further strengthening the research in nanotechnology applications. Dr. Gupta recently received three high end research equipment from JK Tyre: Perkin Elmer Thermogravimetric Analyzer (to determine thermal degradation temperature profile of the polymers and rubber samples), Waters Gel Permeation Chromatography (to determine the polydispersity index and molecular weight of polymers) and Waters Mass Spectrometer (to determine the purity of rubber compounds). The overall idea of having the laboratories of polymer nanotechnology atone of the top universities in Jaipur, JKLU is to give the undergraduate students an opportunity to have a practical feeling of this fascinating multidisciplinary branch of engineering and to promote applied research by involving MTech and PhD scholars. Having collaborations with leading industries and US universities is certainly an additional exciting opportunity to involve selected BTech, MTech and PhD students for advanced training in partner industries and collaborating foreign universities.
