New Practice for Open Hole Flexural Strength of Sandwich Constructions

1. Scope

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.

Keywords

composite materials; sandwich composites; sandwich construction; open-hole flexural strength; flexural testing; notch sensitivity

Rationale

The proposed test method will be used to determine the open-hole (notched) strength of a composite sandwich panel under flexural loading. The notched strength properties of a sandwich construction will be used in material selection, product development, research and development activities, and establishing design allowables.

The title and scope are in draft form and are under development within this ASTM Committee.
