The research teams require testing machines. Sometimes the initial characteristics of these do not meet team specifications, so the electronic instrumentation unit works with doctoral candidates, research technicians and shop to retrofit or create new test systems that are adapted to the studies.
Traditional creep machines apply stress to the specimen by means of a canterlevered arm with weights. Loading is not reproducible, and the test is influenced by surrounding vibrations. When the weights are replaced with a servo-controlled electro-jack and a controller, the machine can be controlled either in loading or deformation modes.
These machines serve to study fibres under creep, relaxation, and fatigue conditions for loading from 0 to 100g (designed and fabricated in cooperation with the Composites division).
This entirely renovated servo-hydraulic testing system machine controls loading and displacement on specimens that are heated by electric current and subjected to rapid temperature variations (1000°C per second).
This machine serves mainly to study cyclical fatigue on polymers:
and adjustable phase shift control between torque and load. The machine was built entirely at the Centre des Matériaux.
