The Material Testing Laboratory are experts in testing the mechanical, thermal, and structural properties of polymer and metallic materials. We ensure that the materials and products that we test, inspect and certify for our customers are safe, compliant, and ready to enter the marketplace. We are well-positioned to support both R&D development projects to comprehensive post-production material testing.
The core function of the 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 and a highly qualified and experienced team that understand manufacturing and manufacturing processes. Due to our aeronautical background, we are well versed in working in a highly regulated environment with a facility that is equipped with state of the art machinery and technology.
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 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
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.
Darnelle is the Internal Special Process Auditor at Aerosud Aviation. He joined Aerosud in 2007. He has a Higher Diploma in Physical Metallurgy from Tshwane University of Technology.
Darnelle has 18 years of experience in auditing and testing of special processes (Composite, Heat Treatment, Surface Treatment, TIG and Spot Welding, etc.). Testing experience includes metallic testing (tensile and hardness testing), spot weld evaluation, metallography testing, composite testing (thermal, chemical, mechanical and themo-mechanical testing).
