FOCUSED MANUFACTURING OF HYPERSONIC MATERIALS
Abstract
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 of manufacturing OFI suffer from high performance property uncertainty and low repeatability. The research objective of this proposal is to determine the physical mechanisms that give rise to performance uncertainty in OFI manufactured using the wet-laid process. The rationale behind the choice of this objective is that this information will reveal new scientific pathways to design materials with tailorable properties and help increase the robustness of the final product by making the manufacturing process more reliable, consistent, and repeatable. We will accomplish our objective through three specific aims- 1) Design and conduct high-throughput manufacturing experiments; 2) Construct and train a probabilistic, causal model of the process; and 3) Uncertainty quantification and reduction. The overall expected outcome of this proposal is the quantification of the effect of process parameters on the performance of the OFI. Specific outcomes include- 1) Extensive datasets containing experimentally measured OFI properties for space-filling designs of wet-laid process inputs; 2) An experimentally calibrated, stochastic, causal model that maps the parameters of the wet-laid process to the properties of interest; and 3) An enhanced understanding of the range and robustness of OFI properties that are achievable through the wet-laid manufacturing process.
