Machine Learning (ML) for efficient optimisation of mould-filling processes in composite manufacturing
Motivation
Continuous-fibre reinforced plastics (CoFRP) are increasingly being used in automotive and aerospace engineering to reduce the weight of load-bearing structures. Among others, the component properties are strongly depend on defect-free manufacturing and optimized process parameters. During component design, manufacturing simulations (e.g. draping or mold filling based on meshed computational methods) are used to ensure and optimize manufacturability.
These simulations show a high degree of reliability, but require long computation times, especially during iterative optimisation. Recently, Machine-Learning (ML) techniques are applied to reduce the computational load during optimisation. These models learn the underlying process dynamics from process samples and can then give recommendations for optimal process parameters.
Thesis subject and goals
The aim of this project is to train an ML-algorithm to estimate optimal injection port positions (process parameters) for variable part geometries in RTM-processing. To this end, an existing ML-framework from will be adapted to interact with an RTM-simulation environment. During ML-training, different geometries of variable complexity will be fed to the simulation environment. Thereby, the ML-algorithm learns, which component design requires which optimal injection port positions. After the training, the algorithm will be able to estimate optimal port positions for a new component without the need for computation intensive optimization.
The thesis is based on existing scripts, which shall be advanced and extended and will be conducted in cooperation with AMT of TU Delft. The thesis’ structure is as follows:
