What Is ASTM D7617 FRP Transverse Shear Strength?
ASTM D7617/D7617M is a standardized test method created to measure the transverse shear strength of fiber-reinforced polymer matrix composites. This test method measures the material’s resistance to a perpendicular shear force.
The test procedure involves applying a controlled transverse shear load to the composite specimens until failure. The test results are used to quantify the material’s shear strength in MPa or psi. ASTM D7617/D7617M is widely used as a test standard in the aerospace, automotive, and construction sectors.

ASTM D7617 FRP Transverse Shear Strength FAQs
The transverse shear strength test determines the maximizing amount of shear strength the material can withstand before failing.
The test is usually used in fiber-reinforced polymer matrix composites, such as carbon fiber-reinforced polymers (CFRP), glass fiber-reinforced polymers (GFRP), and composite structures in aerospace, automotive, and construction industries.
Factors such as fiber orientation, matrix properties, fiber-matrix bonding, manufacturing process, and specimen geometry can all influence the material's transverse shear strength.
Yes, the test is suitable for all types of materials, depending on the material's properties and the test setup's specifics.
