HPC-based Multi-Physics and Multi-scale modelling of the autoclave process for aeronautical components

Presentation of the problem and objective of the experiment

The autoclave process is the main fabrication method for composites used in the aerospace field. This process involves mechanical and chemical phenomena and a lot of variables affect the final result. Therefore, an expensive trial-and-error approach is typically necessary to set a cure cycle for complex shape components in order to reach the requirements and minimize the risk of defects. The objective of this experiment is to optimize, by advanced simulations, the autoclave process maximizing the component quality and minimizing time and costs. 

Short description of the experiment

To optimise the autoclave process parameters taking into account all the concerning variables, a multi-physics and multi-scale numerical model are proposed in this experiment. The analyses will be based on a multitarget optimization criterion to consider the relative interaction between the process parameters and how they affect the defect presence, the fiber distortion and consequently the mechanical performances of the final component. To do this considerable computation resources are required and then HPC infrastructure is necessary. Using these HPC-based simulations it will be possible to drastically reduce the computational time and to set the manufacturing process in a quasi-real-time.
