The advantages of building aircraft structures with composites, compared to metal, include light weight, high specific strength, superior fatigue properties, damage tolerance and the absence of corrosion.
CFRP blades and fan case cut weight for twin-engine aircraft by 700 kilograms
Despite persistent supply chain issues, markets were set for healthy growth before Trump policies and tariffs, yet long-term trends favor composites in new platforms. Meanwhile, advanced air mobility shakes out and moves forward.
FlyZero project posits 279-pax midsize jetliner; will publish technology roadmaps for wings, H2 tanks and cryo fuel systems in early 2022.
Increased commitment expands Rolls-Royce’s test facilities in the Purdue Aerospace District to develop high-altitude and hybrid-electric engines, advances Purdue’s economic development.
Rolls-Royce cites Boeing’s proposed timeline as reason for withdrawing itself from the race to be chosen as engine supplier for the unconfirmed NMA.
Co-located R&D and production advance OOA thermosets, thermoplastics, welding, recycling and digital technologies for faster processing and certification of lighter, more sustainable composites.
New tests, analysis enable databases, models, design guidelines and methodologies, combining materials science with production processes to predict and optimize part performance at temperatures above Tg (≈150-180°C) for wing and engine structures.
Proven in fan blade/case applications, carbon fiber-reinforced polymers migrate to previously unanticipated destinations nearer the engine “hot zone.”
As pressure for commercial aircraft fuel efficiency continues to mount, ceramic matrix composites evolve as they battle metals for application in the engine hot-zone and elsewhere.
