Обновление справочника CMH-17 расширило данные по керамическим композитам для аэрокосмической отрасли

CMH-17 Update to Volume 5 Expands Guidance, Data for CMC Revised Composite Materials Handbook serves as the authoritative reference for composite materials, with new technical content and data on CMC systems, testing and applications. Wichita State University’s National Institute for Aviation Research (NIAR, Kan., U.S.) announces the release of a significant update to the “Composite Materials Handbook (CMH-17) Volume 5.” “CMH-17 Volume 5 Revision B” delivers new technical content and data focused on the growing use of ceramic matrix composites (CMC) in advanced aerospace and propulsion applications. The new revision is available for purchase in print and digital format through SAE International. This revision, led by CMH-17 members from industry, government and academia, expands on critical topics for CMC including a new chapter on engine applications. The latest update reflects increased industry adoption of CMC materials and provides engineers, designers, program managers and students with exclusive guidelines and insight. The release coincides with the celebration of 30 years of coordinated industry efforts CMC materials and processes. Since its inception in 1996, the CMC coordination group has worked to advance understanding, improve consistency, and establish best practices across the field. New and enhanced content includes: - Expanded coverage of environmental barrier coatings, addressing performance and durability considerations for CMC systems. - New guidelines and best practices for CMC testing, supporting consistent and reliable material evaluation. - A new chapter dedicated to engine applications of CMC. - The first CMC dataset to be included in CMH-17: oxide-oxide. Note, this is an interim dataset and does not include B-basis allowables. NIAR serves as secretariat for CMH-17, which holds regular meetings to create, publish and maintain proven material data and engineering information. This material, subjected to thorough technical review, supports the development and use of advanced materials and structures in aerospace applications. Data published in CMH-17 is evaluated under material equivalency requirements established by the Federal Aviation Administration (FAA) rather than under full material allowables programs. This distinction enables users to significantly reduce the cost and time associated with material qualification and aircraft certification, simplifying the effort for broader adoption of CMC materials across the industry.
