RESCOLL carries out mechanical tests on all types of materials such as resin, plastic, composite, metallic, ceramic, wood and chipboard materials … as well as on finished products (sandwich panels, medical devices, …). These tests are performed according to national and international standards (ISO, ASTM, EN, …), specifications and customer test methods (AITM, customer specifications, …).

We support our customers in their R&D projects, product qualifications and series monitoring phases in aeronautics, oil&gas, medical and railway sectors in particular.

We also propose :

  • the development of test methods
  • the design and manufacture of test tools
  • preparation of specimens, in particular via : the manufacture of composite plates, machining, non-destructive testing (A-Scan and C-Scan), instrumentation using strain and stress gauges, heel bonding, the production of bonded assemblies with the supply of substrates (steel, aluminium, glass, composite, etc.) as well as surface preparation (sandblasting, plasma, etc.), equipping the specimens with fittings, etc., installation of anti-buckling systems.

From a testing quality point of view, Rescoll is :

  • COFRAC ISO 17025 and NADCAP accredited
  • Qualified Airbus, SAFRAN, GE

With more than 30 testing machines (fatigue & static) ranging from 0 to 1 200 kN (120 Tons), our mechanical testing department can perform all the following tests* :

  • Smooth traction, inhabited hole or not
  • Smooth compression, with or without a lived-in hole
  • Plane shear +/-45°.
  • 3- and 4-point bending
  • Inter laminar shear stress (ILSS)
  • Single, double, quadruple shearing on sandwich panels
  • Peeling (movable rollers, climbing drum, 90°, 180°, manual, …)
  • Perpendicular traction
  • Matting / Bearing
  • Pull through / Pull out
  • Toughness / Crack tracking (G1C, G2C, K1C)
  • Impact, CAI, TAI and ISV measures
  • Prob-tack or tack to the loop
  • Cleavage
  • Torsion (+/-140°)
  • Rotation (unlimited number of laps)
  • Combined tests: Tension + torsion, Compression + torsion

The specimens can be instrumented with extensometers (mechanical, video, laser), LVDT strain gauges (high precision displacement transducer), acoustic emission sensors or a thermal camera.

These tests can be performed in :

  • Temperature from -180°C to + 500°C (higher temperature on request),
  • Humidity from 20% to 100% (can be combined with temperature)
  • Physiological bath at 37°C
  • Immersion in a liquid
  • After conditioning and/or aging (see environmental testing)

Rendered test reports include the following output data:

  • Force, stress, strain at break
  • Force, stress, deformation at maximum force
  • Force, stress, deformation at the elastic limit
  • Force, stress, deformation at an Offset (Example Rp02)
  • Force, stress, deformation at any other point or event (matting, first break, at a given deformation, at a given stress…)
  • Young's, shear, tensile/compression modules…
  • Fish Coefficient, longitudinal and transverse deformation measurement
  • Test points file for reprocessing
  • Photography of specimens before, during and after testing
  • Photograph of the test set-up
  • Test conditions (standard, operating procedure, date, technician, customer specification, deviation from standard, material used and date of last verification, etc.)
  • Video of the tests…
