G2c Crack Energy: Ensure the interlaminar toughness of your composites
What is G2c Tear Energy and why is it important?
G2c, or the critical energy release rate for interlaminar crack propagation, is a measure of the energy required to initiate and propagate a crack between the layers of a composite material. This parameter is essential for understanding the interlaminar toughness and resistance of composite materials against cracks. Important in industries such as aviation, automotive and wind energy, the measurement of G2c provides valuable insights into the structure and durability of laminated materials.
Why choose G2c crack energy tests?
Do you want to assess the tear resistance and interlaminar toughness of your composite materials? Our G2c crack energy testing services offer:
- Accurate evaluation of interlaminar strength: Understand how well layers in a composite adhere together.
- Increased product reliability: ensure that your composites are resistant to crack initiation and propagation.
- Optimization of material properties: use test results to optimize your laminates and manufacturing processes.
How does the G2c crack energy test work?
The process involves measuring the energy release rate of a composite during the propagation of a crack between laminates:
- End-Notch Flexure (ENF) Test: a common method for determining G2c, where crack energy is measured during the application and propagation of a crack due to flexible stress.
Important standards
- ASTM D7905: this standard test method measures the interlaminar fracture toughness of thermoset and thermoplastic composites. It helps evaluate how well the layers in composite materials are bonded together.
- ASTM E399: this standard describes the test method for fracture toughness, which provides insight into the resistance of materials to crack propagation and is important for G2c measurements.
