ASTM C273 - Standard Test Method for Shear Properties of Sandwich Core Materials
Samples in the form of a sandwich composite plate. Determines the properties of shear force parallel to the faces.
Property measured:
- Shear stress
- Shear strength
- Shear modulus
ASTM C297 - Standard Test Method for Flatwise Tensile Strength of Sandwich Constructions
Square or cylindrical shaped samples of a section of a sandwich composite or core. Valid testing requires failure outside the load-block adhesion line.
Property measured:
- Perpendicular tensile strength of a core or sandwich composite.
ASTM C364 - Standard Test Method for Edgewise Compressive Strength of Sandwich Constructions
Straight sandwich samples without clips suffering force at their ends. Multiple failures can be observed.
Property measured:
- Compressive strength in sandwiches
ASTM C365 - Standard Test Method for Flatwise Compressive Properties of Sandwich Cores
Cylindrical or square section samples of sandwich composite core with tension loading through thickness. Force result should be reported with stabilized or non-stabilized.
Property measured:
- Perpendicular compressive strength of core
- Perpendicular core compression modulus
ASTM C393 - Standard Test Method for Core Shear Properties of Sandwich Constructions by Beam Flexure
Sample in the form of a rectangular sandwich composite plate. Ease of construction and testing. Load applied at three points. Specimen is designed to induce shear failure at the core, but may initiate at its faces.
Measured properties:
- Core shear strength
- Core shear modulus
ASTM D7249 - Standard Test Method for Facesheet Properties of Sandwich Constructions by Long Beam Flexure
Sample in the form of a rectangular sandwich composite plate. Ease of construction and testing. Load applied at four points. Specimen is designed to induce shear failure at the core, but may initiate at its faces.
Measured properties:
- Core shear strength
- Core shear modulus
