Advances in the use of reinforced plastic in parts with greater responsibility and more exposed to cyclic or sustained loads, either due to their function or their location, are highlighting the need to subject such materials to dynamic or creep tests.

In the case of plastic materials, the new production processes derived from additive manufacturing technologies are paving the way for the use of plastic in increasingly specialised applications where dynamic performance is vital.

Although the testing methodologies inherit part of the philosophy of the fatigue and creep tests developed for metal materials, specific properties, such as the dependence of frequency on temperature, and the latter with material performance, as well as the load levels required make fine-tuning and a detailed analysis necessary for each specific material.

Material heating

At TECNALIA, following the development of different projects, we have fine-tuned and carried out a large number of tests to study the frequency effect in material heating, performing tensile fatigue, compression and flexural tests, under different load levels and testing temperatures.

Some of the testing standards under which we work are: ISO 899-1, ISO 899-2, ASTM D7791 and ASTM D3479.

Although these tests, whose ultimate purpose is to verify the durability of the material, are performed on test specimens, they can also be performed on a real part on a test bench.
