ASTM D7078/D7078M — V-Notched Rail Shear Test for Composite Shear Properties
ASTM D7078 is the test method for the shear properties of composites using the V-notched rail shear method. To match this to your program, talk with our team.
What ASTM D7078 Covers
It determines shear strength and modulus by loading a V-notched specimen through rails, applying shear over a larger area than the beam method for higher-load laminates.
How the Test Is Run
A V-notched coupon is clamped in rail grips and loaded at a controlled rate with a shear strain rosette, and the shear properties are calculated from the load and strain.
Why It Matters
Rail shear suits stronger laminates and thicker specimens; a precise fixture and strain rosette are essential.
