Producing new composite materials.
The composite materials are the compound of two or more different nature materials, then obtain the new materials with excellent performance.
The composite technology of timber and other raw materials has matured, so it is feasible to produce new composite materials by using deserted wood furniture materials and other materials, such as wood-metal composites, wood-plastic composites and other new composite materials.

Materials property measurement is needed on deformation, fracture and fatigue in hydrogen-containing media.
At the same time, there is a problem in technological support for evaluation of hydrogen compatibility of materials in laboratory conditions for evaluation of hydrogen embrittlement, depending on hydrogen concentration, methods and modes of loading, temperature, pressure and actual properties of materials.
Evaluation of materials for hydrogen pipelines can be carried out in accordance with the accepted provisions of IGC Doc 121/14, ASME B31.12 and ASME BPVC.VIII.3 (article KD-10) standards.

The material development is aimed at utilizing a suitable Metal Alloy in combination with a most appropriate plastic material considering the achievement of desirable basic features of Smart materials like Shape Memory Effect, Flexibility, recovery time etc.
INTRODUCTION Shape memory alloys are smart materials, remembering their original, cold-forged shape; possessing a tendency of returning to the pre-deformed shape when heated or by providing electrical connectivity [1].
These materials were usually light weight, solid-state alternatives to conventional actuators such as hydraulic, pneumatic, and motor-based systems [2,3].
The recent developments and advancements in the Engineering sector urge for application of smart materials [Shape Memory Composites] in intelligent parts and control systems of Aerospace / automotive sectors [5].
