CSIR-AMPRI pursues R&D activities in the following areas of Engineering Sciences (Materials Science and Technology) and Chemical Sciences
1. Lightweight High Strength Materials
This includes Metal Matrix Composites, Polymer Matrix Composites, Metallic and non Metallic Foams and Nano-structured materials. AMPRI has laid major emphasis on developing lightweight materials like Al and Ti foam, Mg-based alloys, in-situ MMCs, nano-structured materials and polymer composites. Expertise pertaining to material synthesis and processing including process modelling also exists in the Institute.
2. Shape Memory Materials
CSIR-AMPRI is concentrating on developing thermoresponsive shape memory materials through designing and synthesis of (a) closed and open cell SMA foam, (b) Cu-Al based shape memory alloys with high temperature stability and superior mechanical properties including strain recovery, (c) nano-structured Ni-Ti shape memory alloys and composites, and (d) carbon nano tube (CNT)/ nano particle filled shape memory polymer composites..Activities in the area of magnetostrictive (magnetic shape memory) alloys are also being pursued.
3. Nano-structured Alloys and their Composites
Development of nano-structured alloys and their composites has also been the R&D focus of AMPRI. The materials have been found to be an appropriate material system for use as engineering materials with improved characteristics in terms of mechanical, physical, thermal and wear properties.
The continued evolution of separation methods such as chromatography and electrophoresis is driven by the need for a fast analysis of complex mixtures on a smaller scale. At AMPRI, activities have been aimed at developing new analytical methods and applications of electrophoresis & chromatography. This involves the development of processes for the separation of toxicants, pharmaceuticals and bio-molecules and their detection at ppb level using miniaturized separation techniques i.e. high performance liquid chromatography, capillary electrophoresis, miceller electro-kinetic chromatography, microchip based electrophoresis and gas chromatography techniques coupled with UV-Vis spectro-photometry, fluorescence, laser induced fluorescence, electrochemical and mass spectro-photometric detection.
5. Natural Resources and Waste Utilization
This includes the development of natural fibre reinforced composites, lead-free and eco-friendly radiation shielding materials using industrial process wastes such as flyash and redmud, removal of toxic heavy metal ions from aqueous solutions using substrate materials made from low-grade natural minerals, development of glazing material drum filter cake etc.
6. Natural Fibre-Based Construction Materials
A Natural Fibre Composite Development Centre has been established at the Institute to prepare composites using various natural fibres. The objective is to find out environment friendly and/or cost effective substitutes to save wood and replace carcinogenic asbestos fibres in conventional sheets. In addition, the use of natural fibres as geotextiles has also been explored. They also have the potential for use in automobile applications as eco-friendly materials. The main focus of attention has been sisal-based fibres since this xerophytic plant grows abundantly in most of the agro-ecological regions and the fibres have excellent physical and mechanical properties.
