Qualifications

YEAR DEGREE/PROGRAM INSTITUTION
2011 Ph. D., Thesis title: Studies on Microfibrillar based Composites) Mahatma Gandhi University, India

Dr. Jayanarayanan joined Amrita School of Engineering, Coimbatore in the year 1999. Prior to joining Amrita, he was working with BPL-Sanyo Technologies Limited for seven years.  He completed his undergraduate studies at Government Engineering College, Thrissur affiliated with the University of Calicut, and the postgraduate program at the College of Engineering-Guindy, Anna University.

His Ph.D thesis was jointly supervised by Prof. Sabu Thomas (Current Vice Chancellor- Mahatma Gandhi University) and Prof. Kuruvilla Joseph (Dean- Indian Institute of Space Science and Technology). The objective of the work was to develop and characterize in situ composites from immiscible polymer blends.  They are a class of fibre reinforced composites called microfibrillar composites (MFCs) prepared from two fibre forming thermoplastic polymers, created in situ during the manufacturing process. MFC technology provides a unique technique to make use of commingled plastics where both low melting temperature general plastics and high melting temperature engineering plastics co-exist.  MFCs provide an excellent route for the mechanical recycling of fibre forming thermoplastics. The findings of the research work were published in reputed international journals. A chapter was contributed from these studies to the book tiltled “Synthetic Polymer- Polymer Composites” edited by the world renowned polymer scientist Prof. Stoyko Fakirov, published by Hanser Publications, Germany.

Dr. Jayanarayanan’s research interests include Polymer nanocomposites, Multiscale composites, High Performance polymer composites for space and nuclear applications, Polymer process optimization. He was the principal investigator for the ISRO-RESPOND project titled “Polymer Nanocomposites for Inflatable Space Structures” and another project titled “Development of Metal/Poly Ether Ether Ketone Hybrid Composite Laminates for Nuclear Wastage Storage Containers”, funded by BRNS. He was also the Co-Principal Investigator for a DST-CERI project titled “Roll to roll high efficient PET based dye sensitized solar cells fabrication through high temperature sintering process”. Currently he is involved in two other projects, one being funded by ISRO-RESPOND titled “High Performance Polyether Ketone- Carbon Fibre Composite for Future Generation Aviation and Space Applications” and the other, funded by BRNS titled “Development of Boron Carbide Cement Concrete for Neutron Shielding”. Further, he is active in consultancy projects for industries in the field of materials development and process optimization. Some of the completed projects are :

  • Impact modification of of Acrylonitrile Butadiene Styrene for car bumper applications
  • Optimization of scrap usage in rigid PVC pipe extrusion process
  • Optimization of process parameters of an injection moulded Nylon gear to reduce warpage and shrinkage
  • Reduction of Coefficient of Friction (COF) in PVC insulated wires

Two research scholars have completed their PhD dissertations under Dr. Jayanarayanan’s  supervision. Currently he is the Advisor/Co Advisor for four PhD theses. He has also guided several M Tech and  B Tech projects. He has numerous publications in refereed international and national journals and conferences. He also has seven book chapters to his credit. He is the reviewer for the following International Journals

Development of insitu polymer-polymer composites from thermoplastics

A new class of fiber reinforced composites called microfibrillar composites (MFCs) are prepared from two fiber forming thermoplastic polymers. The reinforcing elements are created in situ during the manufacturing process. MFC technology provides an excellent method to make use of commingled plastics in which both low melting temperature general plastics and high melting temperature engineering plastics co-exist. In the work from our group, the properties of MFCs prepared from polypropylene (PP)/ polyethylene terephthalate (PET) and low density polyethylene (LDPE)/PET blends are being analyzed. The static and dynamic mechanical, solvent sorption, and thermal degradation properties of the microfibrillar blends/composites are found to be superior to conventional LDPE/PET blends. MFCs can be prepared with electrically conductive functionalization by making use of conductive fillers. Anisotropically conductive polymer composites can be prepared using this technique. MFC based films are expected to exhibit improved barrier properties qualifying them to be used for packaging applications. MFCs provide an excellent route for the mechanical recycling of fiber forming thermoplastics.

Development and Characterization of Hybrid and Nanocomposites

  • Polymer Nanocomposites for Inflatable Space StructuresFlexible  laminates are prepared  from  different  types  of  PET  films  and  UHMWPE (Dyneema)  fabric  using  polyurethane  based  adhesive.  Peel strength, Lap  shear  strength and  barrier properties are common objectives.  The  effect  of  plasma  treatment  of Dyneema  fabric  on the adhesion  properties  are  analyzed. The incorporation of the nanofillers in the adhesive and its effect on the flexible laminate properties are studied.
  • Metal /Poly Ether Ether Ketone Hybrid Composite Laminates for Nuclear Waste Storage ContainersOur work includes analysis of the effectiveness of PEEK based laminates for nuclear waste storage applications, which have the best of properties, are low in cost, and are relatively easy to fabricate. We also study incorporating radiation resistant nanofillers like boron carbide and tungsten carbide in PEEK matrix by melt compounding. Subsequently surface modified steel is laminated with PEEK nanocomposite plates. The other objective is comparison of radioactive waste storage properties of the above mentioned laminates by bench marking with the conventionally used materials.

Optimization of Polymer Processing Techniques especially Injection Moulding and Extrusion

The quality of the products made by extrusion and injection moulding depends on machine (process) and material parameters. Design of experiments methods are employed to optimize these parameters to achieve the required properties for the products. Some of the work being carried out in this area is listed below.

  • Impact  modification of of Acrylonitrile Butadiene Styrene for car bumper applications
  • Optimization of scrap usage in rigid PVC pipe extrusion process
  • Optimization of process parameters of an injection moulded gear to reduce warpage and shrinkage
