About This Item
ASTM D6742/D6742M is the ASTM standard for filled-hole tension and compression testing of polymer matrix composite laminates. It provides a common reference for evaluating how these laminates perform when a hole is present, which is important because fastener holes and other discontinuities can affect structural behavior. By defining a consistent test practice, ASTM D6742/D6742M helps support more reliable material comparison, engineering decisions, and quality-focused test programs.
ASTM D6742/D6742M standard overview
The ASTM D6742/D6742M standard overview centers on a practical test method for composite laminates with filled holes under tension and compression loading. As indicated by the title, it is intended for polymer matrix composite laminates and addresses the test setup used to assess response around a hole that has been filled. This makes the standard useful when comparing material performance, documenting test results, or aligning laboratory procedures with a recognized ASTM standard for engineering evaluation.
Where is ASTM D6742/D6742M used?
ASTM D6742/D6742M is commonly used in composite testing workflows where filled-hole performance needs to be measured in a controlled and repeatable way. It may be applied in laboratories, material qualification programs, and development work involving polymer matrix composite laminates for structural applications. The standard is especially relevant when a test article includes a hole condition that must be evaluated in tension or compression, such as in research, procurement support, or product verification activities.
Practical importance of ASTM D6742/D6742M
In practice, ASTM D6742/D6742M helps organizations maintain consistency in how filled-hole composite test results are generated and interpreted. That consistency supports compliance efforts, internal quality control, and fair comparison between different laminate materials or suppliers. It can also reduce ambiguity in procurement and technical review by giving buyers, engineers, and testing teams a shared basis for evaluating performance. For composite programs, that clarity may help lower risk and improve confidence in reported results.
