ASTM C297 Flatwise Tensile Strength of Sandwich Constructions
ASTM C297 is a test method that determines the flatwise tensile strength of sandwich constructions by applying a tensile load parallel to the plane of the sandwich face sheets. The sandwich constructions consist of a lightweight core material bonded between two relatively thin, stiff face sheets. ASTM C297 is primarily used for quality control test for bonded sandwich panels, and it can also be used to produce flatwise tensile strength data for structural design properties, material specifications, and research and development of sandwich materials.

Introduction to ASTM C297
ASTM C297 is a standard test method used to evaluate the flatwise tensile strength of sandwich constructions, which are used in a wide range of applications such as aerospace, marine, and transportation industries. The sandwich constructions comprise a lightweight core material bonded between two relatively thin, stiff face sheets. The results obtained through this method are especially useful for material selection, design optimization, quality control, and product development. ASTM C297 evaluates the strength and quality of core-to-facing bonds in a sandwich panel and can also be used to produce flatwise tensile strength data for the core material. The ASTM C297 test method determines the flatwise tensile strength of the core and provides information on the strength and quality of core-to-facing bonds to produce flatwise tensile strength data for the core material.
ASTM C297 test method is generally applicable to sandwich constructions made of various materials such as metals, plastics, and composites. The test method is based on applying a tensile load parallel to the plane of the sandwich face sheets, and the maximum load sustained by the sandwich construction before failure is recorded. MaTestLab has the best network of testing labs in the USA to carry out ASTM C297 tests for our clients.
ASTM C297 Fixture
Factors influencing the flatwise tensile strength by ASTM C297 are: facing material, core material, adhesive material, methods of material fabrication, facing stacking sequence and overall thickness, core density, core geometry (cell size, cell wall thickness), adhesive thickness, specimen geometry, specimen preparation, specimen conditioning, environment of testing, specimen alignment, loading procedure, speed of testing, facing void content, adhesive void content, and facing volume percent reinforcement.
ASTM C297 Test Method
The test method ASTM C297 proceeds by preparing the specimens according to the specified dimensions and conditioning them as per the given guidelines. The specimens are then placed in the testing machine. The method proceeds as follows:
Test procedure for determining properties
The specimens are conditioned as per the specified guidelines and placed in the testing machine. A tensile load is applied parallel to the plane of the sandwich face sheets until failure occurs. The maximum load sustained by the sandwich construction before failure is recorded as the flatwise tensile strength.
Creating test report
A certified report is generated stating the flatwise tensile strength values and other required values that could stand for the specificity of the specimen. The report serves as the certificate of a specimen being durable and reliable for particular applications.
ASTM C297 Specimens
Specimen details
ASTM C297 sandwich constructions consist of a lightweight core material bonded between two relatively thin, stiff face sheets. The core material is made of materials such as foams, honeycombs, and balsa wood, while the face is made of metals, plastics, and composites.
Specimen dimensions
The acceptable specimen thickness for ASTM C297 is specified, with the most commonly used dimensions being 25 mm x 305 mm x 6.4 mm (1 in. x 12 in. x 0.25 in.).
Specimen preparation
Specimens are prepared according to the specified dimensions and guidelines, with particular attention given to the bonding of the face sheets to the core material.
ASTM C297 Results
This test method evaluates the flatwise tensile strength of sandwich constructions, which is an important property for applications such as aircraft and spacecraft structural components, marine and automotive body panels, and sporting goods. The results obtained through this method are used for material selection, design optimization, quality control, and product development.
Tests related to ASTM C297
ASTM C273 is similar to ASTM C297 and covers the test method for determining the shear properties of sandwich constructions. The test method is based on applying a shear load parallel to the plane of the sandwich face sheets, and the maximum load sustained by the sandwich construction before failure is recorded as the shear strength. The shear strength and flatwise tensile strength are both important properties for sandwich constructions, and are often evaluated together to provide a comprehensive understanding of the material’s behavior.
