PROJECTS

The laboratory's staff has been and is involved in research projects with quite diverse themes, derived from the field of both metallic and composite materials, turbomachines, aviation structures and components, the environment, etc.

National Projects

• NUCLEU-PN/2009 - 09.07.07 - Technology Development for Palette Machines 7.1 - Research on the Development of Composite Materials for Palette Machines. The laboratory team has developed three phases in this project:
  - Faza B17 /Numerical simulations on thermal and mechanical demands for choosing the composite structure
  - Faza B18 /Elaboration of preliminary work procedures and working instructions, training on working techniques
  - Faza B19 / Composing the composite bench and trying on the stand. Interpretation of the results obtained and determination of strengths and weaknesses.

International Projects

• OPENAIR ”Optimization for Low Environmental Impact AIRcraft " FP7-234313 (2009-2013). In the 2009-2011 project, a series of demonstration stones were produced representing fan stator blades made of last generation composite materials, lighter than conventional metallic materials. These demonstrations are both a national and international premiere because they incorporate cutting-edge technologies aimed at reducing the weight of civil aircraft to reduce fuel consumption and, implicitly, environmental impact and noise reduction technologies to reduce the impact of aircraft on neighboring communities airports. Physical realization of stator blades was the result of a complex teamwork effort that involved the realization of a complete technological cycle, starting from design / geometry, resistance calculations, designing, composing and testing of composite material to the actual manufacture of using the technology of the autoclave, in the laboratory of composite materials of INCDT - COMOTI. The Institute's activity in this project was completed in May 2011 by providing the prototype - the composite stator palette, the project coordinator, the SNECMA group, France. The encouraging results obtained led to the co-operation of INCDT COMOTI institute for another 2 years within this project (2011-2013).
• CLEANDANUBE „(2I) -2.2-5 Priority Axis: 2 Cross Border Cooperation Program Bulgaria - Bulgaria 2007-2013, ctr. No. 653/2010. The team of the composite materials laboratory is involved in both scientific and technical activities: the selection of materials within the design of the equipment promoted within the project (centrifuge), the finding of optimal technological solutions for the depletion of Danube waters, the preparation of progress reports, and in the activities of dissemination: organizing and participating in meetings, workshops organized both in Romania and Bulgaria, making posters and promotional flyers to promote the project.
• SANDI “Supporting Actions to Create New RDI Partnerships in Trans-border Areas in order to bring together Business and Research for Accessing European Founds, Cross-Border Cooperation Program Bulgaria - Bulgaria, 2 (3i) -3.1-13-MIS-ETC CODE: Ctr. 51766 / 06.07.2011. From the beginning of the project until now, the team of the composite materials laboratory has been involved in activities promoting the training / training of foreign students (Bulgarians) in the laboratory of composite materials in the field of materials science and in particular of composite materials PowerPoint presentations and dissemination at the University of Ruse, Bulgaria).
• TURBOMAT , ID 663, SMIS-CSNR 12607 : “Development of new methods by real and virtual solidification processing of materials with special properties to achieve high temperatures for power turbo engines "POSCCE-A2-O2.1.2-2009-2. From the beginning of the project to the present day, the team of the composite materials laboratory has been involved in: microstructural analyzes and testing of alloys studied, the use of the Pro-Cast virtual solidification program, the interpretation of the results and the preparation of progress reports.
