Advanced ceramic applications set to take-off in the aerospace industry
The demands that are placed on the aerospace industry are only set to increase in line with the rise in passengers and cargo. As such, the use of ceramics will become key, and the technology will take centre stage at the Ceramics Expo and Conference, taking place in Cleveland, Ohio, on 25th-27th April.
As billions more miles are added to aerospace and space travel, there’s an unprecedented necessity for the raft of current technical advances to be built upon. Boeing predicted last year that accommodating the huge increase in passengers and cargo will require 39,620 new airplanes in the next 20 years, at a cost of $5.93tn.
The success of this sector is inextricably linked to ceramics. They contribute much lighter weight, good strength, very high heat capabilities and strong resistance to wear and corrosion. They also provide excellent insulating properties for a number of components. Investment in ceramics for aerospace is at an all-time high, and with good reason. One recent industry estimate, for example, is that there are future potential savings of $1m per aero engine through the use of ceramic matrix composites (CMCs).
Anyone involved in civil or defence aerospace, aviation R&D, space travel, exploration and advanced vehicles and propulsion systems, the free-to-attend Ceramics Expo 2017 is the place to be at the end of April.
Dr Shay Harrison from Free Form Fibers commented: “The development of robust CMC material systems that can withstand the extreme temperature and oxidising environments in both aviation and aerospace platforms for next generation vehicles is a key technology focus. Solving the challenges for reliable CMCs in jet engines will require materials-focused advances in manufacturing, part processing and assessment tools. Similarly, the progress from single use application of exposed aerospace components to multiple-cycle endurance will propel the technical and economic advances in spaceflight.”
Running alongside the expo, there will be the Conference @ Ceramics Expo, a free-to-attend event organised in a twin-track format, offering three days of presentations. The first day will feature strands on ‘Developing Industry Standards for CMC Applications’, ‘Optimizing Ceramic Coating Quality to Improve Reliability’, ‘Evaluating Design Approach for Reliable Ceramic Coatings’ and ‘Developing CMC Manufacturing Processes to Support CMC Adoption’. The speaker roster includes experts from Free Form Fibers, Ceramco, Pratt & Whitney, NASA, 3D Ceram, Morgan Advanced Materials and Oerlikon Metco.
