ASTM D5868 Lap Shear Adhesion for FRP Bonding (Test Method)
ASTM D5868 is the test method for the lap-shear adhesion (apparent shear strength) of adhesively bonded single-lap fiber-reinforced plastic (FRP) joints. To match this to your program, talk with our team.
What ASTM D5868 Covers
It measures the apparent shear strength of a bonded single-lap FRP joint, supporting adhesive selection and bonded-joint qualification.
How the Test Is Run
A single-lap bonded specimen is gripped and pulled in tension until the bond shears, and the apparent shear strength is calculated from the failure load and bond area.
Why It Matters
Bonded-joint shear strength governs the durability of adhesive assemblies; grips and alignment that load the bond in shear are essential.
