Aug 14, 2024 · This test method can be used to provide information on the strength and quality of core-to-facing bonds. It can also be used to produce flatwise tensile strength data for the core material.

The Flatwise Tension (FWT) Test is used to measure the out-of-plane strength of composite laminates. Typically, in this test, solid tabs are bonded to opposite faces of a flat sample from a composite …

Aug 15, 2025 · The Flatwise Tensile test as per ASTM C297 is used to test the bond strength between the core and the facing of sandwich panels. A tensile force is applied perpendicular to the plane of …

This test method, as indicated in Fig. 1, performs a through-the-thickness (flatwise) tensile test of a sandwich panel. The strength of the core, a face sheet, or the bond between the core and a face …

ASTM C297 is a standard test method for determining the core flatwise tension strength or the bond between core and facings of an assembled sandwich panel. The test method involves preparing test …

Oct 24, 2024 · This test method is intended to determine the debonding resistance of the adhesive between the skin and core of a sandwich panel (see Figure ). The specimen should be at least 10 …

May 17, 2023 · 6.3 Geometry—Specific geometric factors that affect sand-wich flatwise tensile strength include core cell geometry, core thickness, specimen shape (square or circular), adhesive thickness, …

The document outlines the ASTM C297/C297M standard test method for determining the flatwise tensile strength of sandwich constructions, focusing on core materials and core-to-facing bonds.

The Flatwise Tensile (FWT) Test is a standardized test (ASTM C297) used by the RV industry to establish a minimum standard for the bond strength of walls and skins in the manufacturing of …

ASTM C297 is in Touchstone’s NADCAP and ISO 17025 scope. ASTM C297 testing determines the flatwise tensile strength of the core, core-to-facing bond, or the facing on an assembled sandwich panel.
