Material Testing

The Aerosud Composite Material Testing Laboratory are experts in testing mechanical, thermal and structural properties of polymer and metallic materials. Our service offering is based on the principle that we ensure that the materials and products that we test, inspect and certify for our customers are safe,  compliant and ready to enter the market place. We are well positioned to offer services from R&D development projects to comprehensive post-production material testing.


Although we are a new entity in the Testing, Inspection and Certification sector, our parent company Aerosud Aviation has a long standing and recognized name in the Aerospace industry.

The core function of the Aerosud Material Composite Testing Lab is to characterize polymer materials.  Our testing is categorised into :


·         Mechanical Testing

·         Chemical Testing

·         Thermal Testing

·         Thermo-Mechanical Testing

Mechanical testing can be performed at temperatures ranging from room temperature to 250 °C.
In addition to polymer material testing, metallic material tensile testing can also be performed.  
All testing is conducted in a controlled environment.  Temperature is regulated at 23 ± 2 °C and the humidity is controlled at 50 ± 5% RH.  Temperature and humidity are constantly measured.

We have a strong culture of collaboration. Our highly qualified and experienced team understand manufacturing and manufacturing processes giving us an edge. Due to our aeronautical background we are well versed in working in a highly regulated environment, coupled with a facility that is equipped with state of the art machinery and technology we are ready to assist you.

Our Offer

Chemical Testing

Determination of resin and fibre content of preimpregnates

Thermal Testing

Differential scanning calorimetry is a thermo-analytical technique in which the difference in the amount of heat required to increase the temperature of a sample and reference is measured as a function of temperature.

Mechanical Testing

Mechanical testing reveals the properties of a material under dynamic or static force. Designed to ensure that materials are suitable for their intended applications, mechanical testing includes methods such as tensile strength, compression strength, impact resistance, fracture toughness and fatigue

Thermo-Mechanical Testing

Dynamic mechanical analysis is a technique used in the study and characterization of materials. DMA testing is useful for studying the viscoelastic behaviour of polymers. The strain in the material is measured by applying a sinusoidal stress to the material being tested over a pre-determined temperature range, allowing one to determine the complex modulus.
