Reducing airframe weight can increase payload fraction, meaning that an aircraft of a given will be able to carry more passengers or cargo. Ultralight airframes functional polymers is an active are on industry.
Many potential functionalities (e.g., self-healing and self-cleaning) have been demonstrated in the laboratory environment. There is also a need to improve the durability and environmental stability of these materials so they can survive at very high or very low temperatures and in corrosive conditions. It would also be helpful to
reduce the need for other additives,which many advanced functional polymers require.
Functional composites are an emerging field with significant opportunity for synthesis and characterization of new composites to achieve the varied applications described above.
These include
• Demonstrate cost-effective methods for processing larger quantities of functional composites
Transition new functional polymers from research laboratories to the sizes needed for aircraft component testing. Develop more robust, formulations that can survive in aircraft environment
• Transition new functional polymers from research laboratories to the sizes needed for aircraft component testing.Develop more robust, formulations that can survive in aircraft environment

What are uses of promising ultralight airframes composites?
The ultralight airframes include the use of foam or structures with integral, durable damage features; highperformance foams for increased strength; directional tailoring and construction; and structural higher methods. Including variable for variable speed morphing wings which reduce their surface weight. Embedding multifunctional structures, such as integral antennas or new novel solar cells, could reduce subsystem weights. A new initiative is needed to integrate these concepts and the associated design along with the substantiating test data, to enable robust, ultralight-weight airframe structures for commercial transport applications. The milestones include • Develop specific ultralightweight airframe concepts,leveraging lessons learned from ultralight aircraft research to develop damage-tolerant and multifunctional composites. • Develop a design and analysis methodology. • Develop a structural optimization methodology. • Perform verification testing. • Demonstrate the potential of one or more compound to reduce airframe weight significantly.
