Interfacial Properties

The Interfacial Shear Strength module (IFSS) is an interchangeable module for our LEX820 Extensometer, used to measure the debonding force of micro-droplets on single fibres and filaments.



The IFSS measurement is based on the universally recognised micro-bond method, which evaluates the interfacial properties between matrix resins/epoxies on fibres and filaments commonly used in composite materials.

The camera and light source enable users to visualise the fibre/droplet during the test and capture the mode of failure in video and still images. The IFSS method can be applied to various fibre and filament types: glass, carbon, ceramic, aramid, basalt or natural fibres.
