Testing Products for ASTM D3039
APP-D3039Determines the in-plane tensile properties of high-modulus fiber-reinforced polymer matrix composites. It measures the ultimate tensile strength, strain, and Poisson’s ratio of anisotropic materials. This configuration focuses on the Newton-Series control architecture to ensure high-fidelity data acquisition. Utilizing a 32-bit digital signal processor, the system provides a superior Signal-to-Noise Ratio (SNR), which is essential for capturing precise material transitions that lower-resolution systems often miss.
The load frame for this application has been selected to provide the most cost-effective solution capable of meeting the standard’s peak force requirements. While TestResources offers a wide range of frame geometries, this specific selection represents the optimal balance between laboratory CAPEX and technical compliance. Any frame in our catalog meeting the minimum load rating will adhere to the standard; however, this configuration is our primary recommendation for those seeking a reliable, streamlined testing platform without unnecessary complexity.=
Explosive Failure: Composites store massive energy and shatter upon failure.
Use Hydraulic or Pneumatic Wedge Grips for 10,000+ psi to prevent slippage.

Implementation Commentary
Data quality is highly dependent on tab bonding and alignment within the wedge jaw.
Common Pitfalls
Jaw breaks caused by excessive clamping pressure or serration bite.
