Nanostructured Poly-DCPD Based Aerogels as Low Cost Thermal and Acoustic Insulation for Aerospace Applications
Agency / Branch:
DOD / DARPA
Aspen Aerogels (AAI) proposes to develop low-cost, lightweight nanostructured poly-DCPD based aerogel composites for aerospace, military, and commercial insulation applications. Alone, the poly-dicyclopentadiene (DCPD) exhibits exceptional properties, including room temperature curable fast processing, good mechanical and physical properties, low cost, and durability. Similarly, the nanopore structure of aerogels presents several unique properties, including low density, and highly effective thermal insulation and acoustic attenuation. Combining Aspens' novel aerogel nanotechnologies with the excellent properties of poly-DCPD will generate low cost and lightweight nanostructured poly-DCPD based aerogel composite materials that have the benefits of both the base polymer and aerogel nanostructure. On Phase I, nanostructured poly-DCPD aerogels will be produced via sol-gel processing followed by either supercritical drying or the chemically induced phase separation (CIPS). Facile ring opening metathesis polymerization reaction of cyclic unsaturated structure of DCPD monomers will be applied to gel monomer within a suitable solvent. The pendant double bonds in poly-DCPD will readily allow for surface modification to augment the capabilities of the new materials. Phase II will scale up development and demonstrate the performance in aerospace and transportation insulation application conditions. The final poly-DCPD aerogel product can be transitioned to production through Aspens' current manufacturing facility.
