Introduction

The U20 Friction Tool is a Matlab tool that predicts tool-ply friction in thermoplastic composites upon forming. The model is based on the Reynolds' equation for thin film lubrication and assumes hydrodynamic lubrication on a meso-mechanical level. The frictional properties are calculated, solely based on the rheological properties of the matrix constituent and the fabric weave geometry.


You can read about the model in the model section. To get started, read the Getting Started section.


You will see three tabs when the program is running.

    1. Matrix material
    2. Weave geometry
    3. Frictional properties

The first two tabs are there to supply the input data on the matrix material and the weave geometry. Once you supplied the required data, the frictional properties are calculated in the third tab.


The U20 Friction tool is free software and comes with no warranty. You can use, redistribute and modify it if you like. If you publish results obtained with this tool (or any tool based on this code), please cite this article.
