Swerea has extensive resources for testing and analysis of composite materials, including everything from the smallest nanoparticles to large composite structures.
Swerea has equipment for experimental characterization of composite materials and products. Examples include hydraulic testing machines for mechanical testing of everything from test pieces to composite products up to 10 metres in length. The climate chamber is used to study the effect of temperature and humidity on material properties.
The structure and properties of composites
The structure of a composite material, its interior architecture, is decisive for its final properties.Optical microscopy is therefore often used for microstructural characterization. Microscopy also allows us to study porosity and the occurrence of other defects. We also apply ultrasound-based non-destructive testing techniques (C-scan) to study the occurrence of defects and delamination in composites.
Analysis before, during and after the manufacturing process
We also perform fractographic studies in which we use various forms of microscopy (SEM, optical) for e.g., failure analyses. The thermal characteristics and rheological behaviour of composites and plastics, before, during and after a manufacturing process, are analysed with the aid of DSC and rheometry.
Swerea also has well-established collaboration with Swedish universities that have equipment that complements our own.
Composites testing in brief:
- Mechanical testing, specimens or structures
- Climate testing
- Nondestructive testing
- Microscopy studies
- Thermal analyses (DSC)
- Rheological analyses
