ISO 527-4: Tensile tests for fibre-reinforced plastics

What is ISO 527-4 and why is it important?
ISO 527-4 is an international standard that specifies the methods for performing tensile tests on fibre-reinforced plastics (VVKs). This standard is essential for determining the tensile properties and mechanical performance of composites that consist of a matrix of polymers and reinforcing fibres. ISO 527-4 provides important information about the durability and reliability of these materials, which are widely used in the aviation, automotive and construction sectors.
Why choose ISO 527-4?
By opting for ISO 527-4 testing, you benefit from:
- Standardised testing methods: Get consistent and reliable results that comply with international standards.
- Understanding composite performance: Get critical data on the mechanical properties of fibre-reinforced materials.
- Optimization of product development: use the test results to improve your design and choice of materials.
How does ISO 527-4 work?
The testing process includes the following steps:
- Sample preparation: Fibre-reinforced plastic samples are carefully prepared according to ISO 527-4 specifications to ensure correct dimensions and surface marks.
- Tensile test: the sample is placed in a tensile machine, where a controlled and increasing tensile force is applied until the material breaks.
- Data collection and analysis: key parameters such as tensile strength, strain at break and elastic modulus are measured and analyzed, which is crucial for assessing the performance of the fibre-reinforced plastic material.
