Reducing dependence on strategic materials and controlling the supply chain are major challenges for the aerospace industry. The Compinnov HT+ program, led by the IRT Saint-Exupéry, aims to develop a French high-temperature composites sector . The objective is to replace imported metal alloys and composites with advanced materials capable of withstanding the extreme conditions of engines and nozzles.
During phase 1, the partners designed innovative formulations: thermosetting matrices, ceramics, and phenolic resins reinforced with carbon or ceramic fibers. Phase 2 (announced in April 2026) focuses on validating these materials. The teams are conducting accelerated aging tests (thermal, mechanical, and chemical) to verify temperature resistance and fatigue cycle resistance.
This program brings together the AID , public laboratories, and major industrial partners (Safran for aeronautical propulsion, MBDA for missiles, ArianeGroup for space, and Liebherr Aerospace for cabin equipment). The objective is to manufacture demonstrators (engine components, nozzles, structural parts) and reach Technology Readiness Levels (TRL) 4-5 with a view to future industrialization.
The development of these composites contributes to the sovereignty of France and Europe and promises gains in lightness, thermal resistance, and performance. GraphMyTech monitors these advances to support its clients in choosing new materials.
