Test Fixtures for ASTM C297 Model: G-ASTM-C297

Flatwise Tensile Strength of Sandwich Constructions. This measures the Bond Integrity between the face sheet and the core. The specimen is glued between two aluminum or steel loading blocks. The technical challenge is the Self-Alignment of the blocks. Any eccentricity in the pull will cause a zipper failure (peeling) rather than a uniform pop failure. MTO’s Flatwise Tensile fixture uses a dual-axis Gimbal or Spherical Seat design to ensure the tensile load is distributed uniformly across the entire bond area. For lead generation, we focus on the Rapid Bonding System—a set of jigs that allow a lab to prepare 10 specimens simultaneously, drastically reducing the labor cost of this mandatory aerospace quality check.
