EN 6033 is the aerospace test method for the Mode I (opening) interlaminar fracture toughness energy of composites. To match this to your program, talk with our team.
What EN 6033 Covers
It determines the Mode I fracture toughness of aerospace composite laminates, characterizing resistance to opening delamination.
How the Test Is Run
A double-cantilever-beam specimen with a starter crack is loaded to open the crack while load, displacement, and crack length are recorded, and the toughness is calculated.
Why It Matters
Mode I toughness is a damage-tolerance requirement for aerospace composites; accurate load, displacement, and crack tracking are needed.
