Tests in composite materials

Sourtec is an exciting well equipped company offering a wide range of testing and evaluation services for composite materials and structures, from small-scale to full-size composite structures. We are now committed to the certification and testing of this promising material and, hence, understand the intricacies that come with the use of composite materials when compared to traditional ones.

Whether you are looking for independent evaluation of your composite structure, qualification of a particular composite, or testing of a single batch of specimens, Sourtec will be glad and ready to assist you.

Below you will find a list of test methods (and their respective standards that we perform in accordance with) in composite coupons that we are experienced to deal with:

Tensile: ASTM D3039 and D638;

Compression: ASTM D6641;

Open hole Tensile/Compression: ASTM D5766 and D6484;

Shear: ASTM D3518 and D7078;

3- and 4 point bending: ASTM D7264;

Interlaminar shear (short beam): ASTM D2344;

Short- and long-term creep testing;

Accelerated weathering: ASTM D5229;

Weathering in agressive enrironments;

Fatigue under particular loadings;

Tensile strength for cylinders: ASTM D2290;

Fractographic analyses.

In addition, we have suitable facilities and experts within our R&D Team to carry out tests in full-size structures, such as:

Internal pressure tests for composite cylinders & pressure vessels: ASTM D2992

Since we have a very interdisciplinary Team and one of our key expertises is corrosion engineering, our team is working extensively on the development of new features to evaluate the aforementioned mechanical tests under agressive environments, such as H2S and CO2, and under temperature and/or pressure.

Furthermore, Sourtec has experts on the design and structural analysis for composite structures through the finite element method, looking for provide you a more reliability and safety for your structure when it is subjected to extreme and complex loadings. This will enable you to have the best performance of your composite: high strength and stiffness, low weight, and low susceptibility to fatigue and corrosion.
