Composite Materials Laboratory

There are three main focus areas of the "Composite Material Laboratory".

The first focus area is the thermal and mechanical characterization and behaviour of composite materials, including base resin systems and fiber reinforced composites.

The second focus area is the composite manufacturing of fiber reinforced composite which involves issues like toughening mechanisms used for resin systems, techniques to improve damage tolerance of composite materials, resin flow simulation of processes such as resin transfer molding, vacuum infusion, permeability test and simulation of different fabric forms and resins systems, the effect of manufacturing method on mechanical characteristics of fiber reinforced composites etc.

The third area is the design, analysis and optimization of structures composed of composite materials.

Composite Material Laboratory concentrates on three key areas:

  •  Composite Material Characterization
  • Composite Material Manufacturing
  • Design, analysis and optimization of structures composed of composite materials


Laboratory makes uses of experimental and numerical simulation techniques in the characterization, manufacturing and design, analysis and optimizatio of composite materials.

     

Experimental equipment

  • DMA (Dynamic Mechanical Analyzer)
  • DSC (Differential Scanning Calorimeter)
  • TGA (Thermal Gravimetric Analyzer)
  • UV-VIS Spectroscopy
  • FTIR (Fourier Transform Infrared Spectroscopy)
  • Accelererated Weather Testing (Planned)
  • Polarized microscope (Planned)
  • Rheometer (Planned)
  • Non-destructive inspection system (Planned-Shearography)
  • Mechanical testing machines (100kN tension/torsion-dynamic,250kN tension-compression-dynamic)
  • Digital Image Correlation System (DIC-Aramis 4M/Pontos)
  • Vacuum infusion system (The existing system will be improved)

Simulation software

  • RTM-Worx (resin flow simulation software)
  • MSC Patran-Nastran (Finite element software)
  • CATIA (Computer aided design tool)
  • Abaqus (Finite element software)
  • Hypersizer (composite analysis and optimization software)
  • Samcef (Finite element software)
  • S4WT (Software for the design and analysis of the wind türbine systems, wind turbine aeroelasticity)
  • Genesis (Structural optimization software)
  • Visualdoc (General optimization software)
  • VABS (Cross-sectional analysis software)

Laboratory will serve for two main purposes.

  • Composite material characterization, manufacturing and design and analysis service to the wind türbine industry, especially in the area of rotor blade development
  • Research in the area of composite materials, composite manufacturing and design, analysis and optimization of wind türbine blades

 

Note: The next generation turbine systems will be high power systems with very long blade lengths. Design of very long blades requires the application of new materials and manufacturing concepts to control excessive deformation of the blades, and to reduce weight.
