A laminate is a type of composite material, manufactured by assembling several layers of different materials, consolidating by the application of pressure, heat and adhesives in to semi-finished products like sheets or finished shapes. A simple example is a metal polymer laminate, which has a sheet metal adhesively bonded to a polymer films or sheets. There may be many layers of plastic sheet and metal sheets, which are called multilayer laminates. In some cases, polymer sheets may be replaced by foam sheets or woven fabric made of high strength glass or carbon or polymer fibers. Mechanical, physical and chemical properties of laminates are important for application development.
Laminates are tested just like a metal or polymers sheets in tension, compression, shear, torsion, etc. But there are some testing unique to laminates. These are peel test, swell test, lap shear test, water resistance test, etc.
Capability – At Touchstone testing laboratory, we have capability to test sheet, bar, rod or tube laminates for mechanical properties like tension, compression, shear, flexure, fracture, fatigue, creep, etc., and physical properties like density, thermal conductivity, dielectric strength, etc. We also have capability to test hardness, abrasion and wear resistance, damage tolerance, water resistance, swell properties, interlaminar properties like shear, peel, etc., of laminate materials.
Some useful standards:
Touchstone is committed to providing its customers with quality, reliable test results. That is why we have undertaken the rigorous steps needed to meet and secure the most stringent of test lab accreditations including ISO/IEC 17025, NADCAP 7101 (Materials Test Lab) and NADCAP 7122-I (Non-Metallics Materials Testing).
