Material Testing

The Aerosud composite laboratory’s main function is to characterize polymer materials.  Testing is categorised into the following types:

 

  • 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 performed in an environmentally controlled environment.  Temperature is controlled at 23 ± 2 °C and the humidity is controlled at 50 ± 5% RH.  The temperature and humidity are constantly measured.

Aerosud can provide testing as per the list of tests, as well as the following services:

  • Consult on the testing required and provide advice on testing methodologies

  • Aerosud can be a one stop solution for all testing requirements, i.e. finding test laboratories for tests that we cannot perform in-house.  One report is issued with all test results

  • Evaluation of test results

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.
