Ceramics Take to the Skies
As the use of ceramic parts in the aerospace industry takes off - Ceramics Expo and Conference uncovers the latest technical ceramic opportunities, trends and innovations.
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 $5.93 trillion.
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, 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).

If you are involved in civil or defense aerospace, aviation R&D, space travel, exploration and advanced vehicles and propulsion systems, the free-to-attend Ceramics Expo is the place to be.
Dr Shay Harrison from Free Form Fibers comments, “The development of robust CMC material systems that can withstand the extreme temperature and oxidizing 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.”
Conference @ Ceramics Expo 2017 once again attracted delegates from this sector, a free-to-attend event organized in a twin-track format offering three days of stimulating presentations. The first day alone was enough to whet the appetite, with 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 included experts from Free Form Fibers, Ceramco, Pratt & Whitney, NASA, 3D Ceram, Morgan Advanced Materials and Oerlikon Metco.
At Ceramics Expo 2018 you’ll be spoilt for choice, including the following:
Ceramco provides precision-manufactured ceramic fasteners.
CeramTec North America was also successful in gaining AS9100; new products will come from the Laurens, SC facility as aerospace business is expanded.
Cleveland Electric Laboratories supports turbine engine manufacturers needing to perform extensive testing for new designs; it fabricates specialty temperature and pressure probes, performs modification machining of customer components and installs temperature, pressure and strain gauges.
Corning’s high-purity fused silica has formed the windows for all of the manned spacecraft in US history; its specialty glass-ceramic materials were chosen for missile nose cones.
Advanced glass materials from Elan Technology play an integral role in aviation and avionics sensors. The company develops materials that can withstand harsh conditions while maintaining reliability and accuracy. Brakes, flaps, fuel components and hydraulic sensors all incorporate Elan’s glass materials.
Enduring brilliance for aircraft exteriors is provided by effect pigments from EMD Performance Materials, which offers a broad range of styling options to manufacturers of aerospace paints and coatings, combining unique color intensity with excellent weathering durability.
Free Form Fibers has developed the capability to fabricate silicon carbide fibers for CMCs to use in hot section components in turbines.
IMR Test Labs verifies, analyses and tests. It has extensive experience with reciprocating and turbine engine components/materials, airframe materials and thermal spray coatings.
Materion Ceramics has refractory coatings that protect leading-edge surfaces such as turbine blades and nose cones; also, its temperature- and abrasion-resistant tiles shield spacecraft upon atmospheric re-entry.
The POCO family of aerospace graphite and ceramics is being used in tribological and structural applications in the core of next-generation engines: bushings, washers, bumpers, guide rings and seals operating up to 1,200ºF (650°C).
PremaTech Advanced Ceramics makes ceramic parts for fighter jets, space systems, tactical missiles, jet engines and satellite communication system.
Superior Technical Ceramics includes ceramics for instrumentation, control, engine monitoring, guidance, optics and turbine ignition systems.
