EN 6034 — Mode II interlaminar fracture toughness (GIIC) for carbon-fibre composites

EN 6034 · EN standard

EN 6034 is the aerospace test method for the Mode II interlaminar fracture toughness energy of composites. To match this to your program, talk with our team.

What EN 6034 Covers

It determines the Mode II fracture toughness of aerospace composites, characterizing resistance to shear-driven delamination.

How the Test Is Run

An end-notched flexure specimen with a starter crack is loaded in bending so the crack grows under shear, and the toughness is calculated from the load and crack length.

Why It Matters

Mode II toughness is a damage-tolerance requirement for aerospace composites; accurate load and crack measurement are needed.
