ISO 14126 Fiber Reinforced Plastic Composites - Determination of In-Plane Direction Compression Properties

The EUROLAB laboratory provides testing and compliance services under the ISO 14126 standard. This International Standard specifies two methods for determining the compression properties of fiber-reinforced plastic composites in directions parallel to the lamination plane. Compression properties are of interest for specifications and quality control purposes.

ISO 14126 Fiber Reinforced Plastic Composites - Determination of In-Plane Direction Compression Properties

Two loading methods and two types of specimens are described; these:

Method 1: provides shear loading of the sample (measure length not supported).
Method 2: allows final loading or mixed loading of the sample (measure length not supported).

For tab-loaded specimens end-loaded using Method 2, some load is transferred to the specimen gauge length by shearing via the tabs.

Type A sample: Rectangular section, constant thickness, with end tabs.
Type B sample: Any combination of test method and sample may be used, provided that the requirements for a rectangular section, thickness range, without strip or with end strip (two sizes are available) are met and the specimen is representative of the material being tested.

These alternative test conditions will not necessarily give the same result. Type A sample is the preferred sample for unidirectional reinforced materials tested in the fiber direction.

A or B type sample can be used for other materials. B2 type sample, matte, fabric and
preferred for other versatile reinforced materials.

The methods are suitable for fiber-reinforced thermoplastic and thermoset plastic composites.

Non-reinforced and particle-filled plastics, as well as plastics reinforced with short fibers (less than 1 mm in length) are covered by ISO 604.

The methods are performed using samples that can be processed from a test panel or finished or semi-finished products made in accordance with ISO 1268 or equivalent methods.

The methods specify the dimensions required for the sample. These are tests performed on samples of other sizes or on samples prepared under different conditions.
