ASTM C297
Engineered in strict accordance with ASTM C297, our flatwise tensile strength fixture is designed to determine the tensile strength of sandwich cores and the core-to-facing adhesive bonds. Featuring a built-in universal alignment joint, it ensures perfect axial loading by preventing off-axis forces that could compromise test accuracy. Equipped with easily interchangeable loading blocks to accommodate various specimen sizes (from 25×25 mm to 75×75 mm), this robust steel fixture handles loads up to 50 kN and operates in extreme temperatures (-70 to 300 °C). It is an essential tool for quality control and structural design of bonded sandwich panels in the aerospace and advanced materials industries.
Overview
Engineered in strict accordance with the ASTM C297 standard, this fixture is designed to determine the flatwise tensile strength of sandwich constructions. The test method involves applying a uniaxial tensile force perpendicular to the plane of the sandwich panel. The load is transmitted to the sandwich specimen through loading blocks bonded directly to the sandwich facings or the core itself. This fixture provides critical data on the flatwise tensile strength of the core, the core-to-facing bond, or the assembled sandwich panel. It is primarily used for quality control testing of bonded sandwich panels, while also delivering essential strength data for structural design, material specification, and research and development applications.
