Optimization of the fiber/matrix interface strength - numerical simulation of debonding in thermoplastic composites

The objective of this project is to set-up numerical tools for the determination of fiber/matrix properties in CF/thermoplastic matrix, which could be used further on in order to control the fiber-matrix interface to optimize the composite fracture properties. The link between the fibre-matrix properties and that of a unidirectional ply or yarn will be investigated. Numerical simulations of the fiber/matrix interface are envisioned in order to set-up post-processing approaches of dedicated micro-mechanic tests.
