ISO 14130 Fibre-Reinforced Plastic Composite – Determination of Apparent Interlaminar Shear Strength by Short-Beam Method

The ISO 14130 test method covers the determination of the apparent interlaminar shear strength (ILSS) of fiber-reinforced plastic composites by the short-beam method.

The method is suitable for composites with either a thermoset or thermoplastic matrix.

The data obtained is not suitable for determining the design parameters, but it can be used for screening materials or for quality control.

So with the various test samples there will also be variation on the failure mode, which is dependent on the fiber lay-up procedures used during manufacturing.

Test Fixture

Three-point beam flexure testing per ISO 14130, is used to determine the apparent interlaminar shear strength of fiber-reinforced plastic composite materials.

The short-beam strength is of interest for screening materials or for quality control of composite materials.

The beam flexure test is performed by placing the specimen symmetrical 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 interlaminar shear failure occurs.

The standard addresses fibre-reinforced thermosetting and thermoplastic composite materials.

 Servohydraulic Test Systems or Electromechanical Universal Test Systems are ideal for performing accurate and repeatable monotonic testing of

fiber-reinforced plastic composite materials per ISO 14130.

*** Before conducting ISO 14130. , it is important to read the entire specification. Standards can be obtained from appropriate standard authorities.
