BS EN 2563 – Aerospace Series – Carbon Fibre Reinforced Plastics – Unidirectional Laminates
Determination of Apparent Interlaminar Shear strength
The target of the standards EN 2563 / ASTM D 2344 to determine the short-beam strength of high-modulus fibre-reinforced composite materials.
This standard mostly is used for reinforced carbon fibre material as part of quality production control for supervision if the interlaminar connection of resin / plastic
and carbon fibre was done properly. Because the specimen is relatively short this is so called short beam specimen (SBS).
The test hast to be performed with a universal testing machine with a force of 5 kN minimum (class 1) and a 3-point-bending tool.
Typically this test will performed at unidirectional specimen of carbon fibre plastic for aircraft industry.
The shear strength determined corresponds to the maximum shear stress in the damage of the neutral fibres of the test specimen.
The interlaminar shearing stress is determined parallel to the laminate layers in order to obtain a qualification via the fibre and matrix connection.
Standards DIN EN 2563 and ASTM D 2344 are similar in execution and experimental design, but differ in test specimen geometry, the test speed and the test tool.
Universal Testing Machine class 1 Load cell ~ 5 kN or higher (max. 25 kN)
3-point-flexure test apparatus for max. load 5 kN
*** Before conducting BS EN 2563 , it is important to read the entire specification. Standards can be obtained from appropriate standard authorities.
