About the Project

This project will create new optimisation tools that can help the development of the manufacturing process of large-scale, high-value composite parts. Although numerical simulation is an integral part of the design process of any composite parts, it has struggled to make progress in helping the development of their manufacturing processes. This is largely due to the current lack of scalability of process models and the difficulty to analyse full-size industrial components. This project will build on recent breakthroughs made at Bristol Composites Institute in the development of fast simulation tools for the prediction of consolidation-induced defects in thick autoclave moulded composites parts. The project is co-funded by Airbus and will look more specifically at the thermoforming of thick thermoset prepreg stacks.

The main objectives of the project can be summarised as follows:

1.      Implement a solid-shell element for the thermoforming of thick prepreg stacks;

2.      Integration of BCI’s homogenised formulation for thick prepreg stacks into the newly developed element;

3.      Investigate strategies to define Bayesian optimisation techniques with a particular focus on the methods used to generate a synthetic dataset that can be used to train a surrogate model of Airbus’ component manufacturing process;

4.      Contribute to technical reporting and dissemination of scientific outcomes through publications and participation in international conferences.

The project will be based in the Bristol Composites Institute (BCI), a world-leading research centre at the University of Bristol. The institute has over 150 researchers and works closely with the £60M National Composites Centre, which is a wholly owned subsidiary of the University engaged with industry to fully exploit and develop composites technology. The student will be expected to make a number of visits to Airbus’ facilities in Toulouse (France) during the duration of the project.
