Determination of the Mode II Interlaminar Fracture Toughness of Polymer Composites
The determination of the mode II interlaminar fracture toughness of polymer composites is typically performed according to standardized test methods. The most commonly used standards for this purpose are ASTM D7905-17, which outlines the end-notched flexure (ENF) test method, and ASTM D7906-17, which outlines the four-point bending (4PB) test method.
ASTM D7905-17 describes the ENF test method for determining the mode II interlaminar fracture toughness of unidirectional polymer matrix composites, while ASTM D7906-17 describes the 4PB test method for the same purpose.
Both standards provide detailed instructions for specimen preparation, testing conditions, and data analysis, and are widely accepted in the industry and academia for determining the mode II interlaminar fracture toughness of polymer composites.

In addition to these standards, other organizations such as ISO and JIS also provide guidelines for determining the mode II interlaminar fracture toughness of polymer composites. ISO 15024:2016, for example, provides a method for determining the mode II interlaminar fracture toughness of fiber-reinforced polymer matrix composites using the ENF test, while JIS K 7079:2017 outlines the test method for determining the mode II interlaminar fracture toughness of fiber-reinforced plastics using the 4PB test.
It is important to note that the determination of the mode II interlaminar fracture toughness of polymer composites can be affected by several factors, such as the specimen geometry, testing conditions, and the presence of defects or damage in the material. Therefore, it is important to carefully follow the appropriate testing standards and protocols to ensure accurate and reliable results.
