The Committee will develop standard test methods, practices, terminology, and guides; sponsor symposia; stimulate research; and exchange technical information pertaining to composite materials (primarily those with fibrous reinforcement), as well as to reinforcing fibers with a Young's modulus greater than 20 GPa (3x10(6) psi).
This Committee will develop standard specifications for composite materials used in civil structures under Subcommittee D30.10. Other subcommittees under this Committee will not develop standard specifications. All other subcommittees shall be unclassified, as they do not develop standard specifications.
The work of this Committee will be coordinated with other ASTM committees and other organizations having mutual interest.
J-integral; interfacial fracture test method
Existing interlaminar fracture toughness test methods rely on linear elastic fracture mechanics principles which may not apply to fracture of high-fracture toughness structural adhesive materials used in bonded composite structure. A new test method to characterize interfacial fracture of these adhesives would provide helpful engineering information, including design allowables and input data for progressive damage analysis tools. Potential users include manufacturers of bonded composite structure, academic institutions, government agencies, and other researchers in the field of composite materials.
The title and scope are in draft form and are under development within this ASTM Committee.
