Test Method Summary
Three-point flexure testing of fibre-reinforced composites per EN 2746 is done to determine the relevant property data for material screening or quality control.
The flexure test is performed by placing the specimen symmetrically on the support fixture that is mounted either to a servohydraulic or an electromechanical testing machine. The load is applied to the specimen at mid-span until failure occurs. The specimen deflection can be measured with a deflection measuring device. Properties that are measured include flexural strength, flexural modulus and other aspects of the flexural stress/strain relationship. This standard addresses glass fibre-reinforced plastics for aerospace applications.
Testing solutions for EN 2746 typically include these types of components:
Load Frame Options
The MTS Landmark® servohydraulic test systems and MTS Criterion® electromechanical test systems are ideal for performing accurate and repeatable monotonic testing of glass fibre-reinforced plastics per EN 2746.
The innovative frame design of the MTS Landmark system exhibits superior stiffness and alignment capabilities. The test system integrates the latest servohydraulic technology, including precision-machined columns for consistently tight alignment; fatigue-rated MTS actuators with low friction bearings for long service life; and smooth-ramping hydraulic service manifolds for bumpless starts. With the addition of an energy-efficient, SilentFlo™ hydraulic power unit, the MTS Landmark system can provide optimum performance and efficiency.
The 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 fixture misalignment.
