Test Method Summary
Tensile testing of unidirectional carbon fibre reinforced composites perpendicular to the fibre direction per EN 2597, is used to determine mechanical material property data. Uniaxial tensile force is applied to a flat test specimen to investigate the stress/strain behavior and critical materials properties including tensile modulus, tensile strength, elongation at break, and Poisson’s ratio. This standard only addresses unidirectional carbon fibre-reinforced composite materials with the axis perpendicular to the fibre direction.
The tensile test is performed by placing a test specimen in the grips of either a servohydraulic or an electromechanical testing machine and subjecting it to controlled tension load until failure. The specimen response can be measured with a contacting or non-contacting extensometer, or strain gages.
Solutions for EN 2597 typically include these types of components:
Load Frame Options
The MTS Landmark servohydraulic test systems and MTS Criterion electromechanical universal test systems are ideal for performing accurate and repeatable monotonic testing of carbon fibre-reinforced plastics per EN 2597.
The MTS Landmark system’s innovative test frame design exhibits superior stiffness and alignment capabilities. The test system integrates the latest MTS servohydraulic technology including precision-machined columns for consistently tight alignment, fatigue-rated MTS actuators with low-friction bearings, smooth-ramping hydraulic service manifolds, and SilentFlo™ hydraulic power units that are quiet enough to be located directly in the laboratory.
The compact MTS Criterion test system features high-resolution MTS digital controls, linear motion guides for superior alignment, high-speed, low vibration MTS electromechanical drives, optional Dual Zone test space for maximizing efficiency and anti-rotation grip/fixture mounting to minimize shear stresses on the specimen.
