Mechanical Test
 Determination of the mechanical properties at constant temperature (range of temperatures: from -70ºC up to 250ºC): tensile tests, three-point bending tests, compression and compression in flat deformation tests.
Specific test of Mechanism of the fracture: toughness determination (KIc and GIc), determination of J0.2 and JIc, construction of resistance curves J-R, determination essential work of fracture.
Determination of the impact strength: pendular impact (Charpy, Izod, Impact-traction), falling dart impact (-40 ºC up to 150 ºC)
Determination of the fracture toughness by instrumented impact
