Testing & monitoring

Control laboratory & testing

In addition to a tight control of process parameters and incoming raw materials, Epsilon has a long experience of physico-chemical testing (Tg / DMA, DSC, microscopic observations, etc.) and mechanical testing (tensile/compression tests, bending, fatigue, ILSS, etc.)

Our laboratory is also an essential component of our R&D effort, since it allows us to test the performance of the innovative materials we develop, as well as to verify the consistency of our predictive simulations through real tests.
These tests can simulate ageing or environmental aggressions (UV, high temperature, humidity, contaminating fluids, etc.)

Non Destructive Testing

Epsilon has developed a strong expertise in various non-destructive testing technologies that make it possible to detect any defects in the composite parts we produce (delamination, porosity, foreign bodies, dimensional variations).
These methods are particularly used in areas such as energy and aeronautics, where the conformity of parts is crucial for safety.

Some of the Non-Destructive Testing methods used by Epsilon Composite:

  • Ultrasounds
  • Micro-tomography (X-rays)
  • Infrared…

Epsilon has also developed several innovative monitoring technologies specifically for High Voltage conductor cores, according to customer requirements. This includes optical fibers, or other options based on Epsilon patented technologies.
