EN 2563 — Apparent Interlaminar Shear Strength (ILSS) of Unidirectional CFRP

← Back to all standards

EN 2563 is the aerospace-series test method for the apparent interlaminar shear strength of carbon-fibre-reinforced plastics. To match this to your program, talk with our team.

What EN 2563 Covers

It determines the apparent interlaminar shear strength of CFRP by short-beam bending under the aerospace framework.

How the Test Is Run

A short-span CFRP specimen is loaded in three-point bending until it fails, and the apparent ILSS is calculated from the peak load and cross-section.

Why It Matters

ILSS indicates interlaminar quality for aerospace CFRP; a rigid short-span fixture is required.
