We used a micromechanical model to predict damages in thermoplastic composites and to understand their controlling parameters. We found that the ductility of the composite is mainly affected by inter-fibre distance rather than matrix ductility.

This study aims to predict the mechanical properties of the paper layer by using a three-scale approach. The homogenization was performed first on the fiber wall level, and then on the generated artificial fiber network.

Computed Tomography was used to capture Mode I delamination propagation in particle-toughened carbon/epoxy laminates. Digital Volume Correlation was used to quantify the strains ahead of the crack tip, which were compared to a plane strain FE model.

An embedded cell simulation approach is used to study the toughening due to bridging in a unidirectionally reinforced carbon/epoxy composite in mode I intralaminar fracture.

The competing mechanisms of debonding and matrix failure are treated with an analytical approach. It is shown that there exists a value of the fibre radius which discerns between a matrix and interface driven damage initiation.

This study focuses on the propagation of a transverse crack, for a cross-ply laminate, inside the interleaf reinforced by thermoplastic particles. Trends in crack propagation were anticipated depending on main properties of the matrix and particles.

Analytical and FE methods were used to analyse how stress redistribution varies with the number of broken fibres in a cluster. A FE model to predict the survival probability of microcomposites is also presented and validated against experiments.

A numerical framework for damage development in micro-scale UD-FRP composite with continuous fibers has been presented in this work. Multiple damage modes, viz., fiber breakage, matrix plasticity and fiber-matrix interface debonding has been simulate.

This work is a numerical study to evaluate the influence of carbon nanotubes (CNTs) on the stress build-up in and around a broken fibre in a single carbon fibre/epoxy composite. The studied modifications on the fibre surface are CNT growth and sizing.
