Metallized Ceramic-Based Structural Insulators

An ideal structural insulator will not outgas, will not change significantly with respect to material properties and geometry during elevated temperature exposure, will have the necessary thermal conductivity/diffusivity for insulating purposes, and will have the necessary stiffness to provide proper support.Metallized ceramic-based structural insulators are anticipated to offer improved performance compared to rayon-based fiber CCP composites and many other fiber composite materials.The anticipated performance enhancements of metallized ceramic-based structural insulators will allow for improved insulating capabilities, higher maximum temperature use (with Ultra High Temperature Ceramics, UHTCs), more robust Inter-Pulse Delay (IPD) times for dual-pulse motor applications, longer burn times, and cost savings.This advanced materials system will be demonstrated during the Phase II research and development by a work plan that has tasks related to: 1) design and analysis; 2) manufacturing trials and material fabrication; 3) material characterization and experimentation; 4) data evaluation and material/design improvements; 5) fabrication of components for static testing; 6) static testing; and 7) reporting and travel.Approved for Public Release | 18-MDA-9522 (23 Feb 18)
