ASTM D7249 Long Beam Flexure Fixture for Sandwich Constructions
Engineered in strict compliance with ASTM D7249, this Long Beam Flexure Fixture for Sandwich Constructions is designed to evaluate the flexural properties of composite sandwich panels, such as honeycomb structures. Featuring an adjustable span and a unique roller-connected loading pad design, it ensures continuous and uniform contact with the specimen throughout the test. Capable of handling loads up to 50 kN, it delivers precise measurements of flexural strength, modulus, and maximum strain — making it an essential tool for advanced composite material analysis and structural design.
Overview
Engineered in strict accordance with ASTM D7249 standards, this fixture is designed for long beam flexure testing of sandwich constructions. It provides a reliable testing platform to evaluate the flexural properties and structural integrity of composite sandwich panels.
