Abstract Scope |
Opacified fibrous insulation (OFI) is a potentially high-performance, low-cost choice for effectively dealing with radiative heat transfer in hypersonic applications. However, current approaches to manufacturing OFI suffer from high-performance property uncertainty and low repeatability. This work aims to optimize processing conditions that minimize the performance uncertainty in OFI manufactured via the wet-laid process. To achieve this, we propose a Bayesian optimization approach to reduce the variability in thickness and grammage of the manufactured OFI sheet. Unlike conventional Bayesian optimization, where only one experiment is suggested for the next iteration, we provide a mathematical framework that can suggest a batch of experiments to be performed. This framework is particularly advantageous when the process conditions can be alerted during manufacturing. We introduce this framework using a toy example and discuss results obtained from the manufacturing process of the OFI sheets. |
