Interlaminar shear strength test

We offer:

  • Experiment design
  • Sampling and conditioning of composite materials
  • Interlaminar shear strength and stiffness at room temperature
  • Interlaminar shear strength and stiffness at cold temperature (down to -150°C)
  • Interlaminar shear strength and stiffness at elevated temperature (up to 280°C)
  • Statement of conformity to specification

Equipment (selection):

  • Instron electromechanical testing machine (max. static load up to 100 kN, crosshead displacement up to 1000 mm, load cells with ranges ±1 kN, ±10 kN, ±100 kN)
  • Hydropuls Schenck servo-hydraulic machine (max. static load up to 250 kN, crosshead travel up to 100 mm)
  • test conditioning chambers (test environment in the range -150°C ÷ 280°C)
  • Climacell conditioning chamber (long-term environment of elevated temperature and humidity, typically 70°C at 85% r.h.)
  • Kimo Instruments thermocouple loggers (specimen temperature measurement in the range -180°C ÷ 480°C)
  • Mechanical axial and dual extensometers (measurement of specimen strain in the longitudinal and transverse axes)
  • X-Sight optical extensometer (strain measurement and digital image correlation (DIC))
  • mechanical and hydraulic jaws
  • test fixtures according to the relevant standards
