Research Topics


BMDO has identified a need for high performance structures and propellant tanks for use in Kinetic Energy Kill (KEK) vehicles. APT Aerospace, Inc. has developed a unique system for polymerizing DiCycloPentaDiene (DCPD) monomer into a robust polymer suitable for many aerospace applications. This polymer has many excellent properties, including: high strength, amenable to fiber reinforcement, high impact strength and toughness, corrosion resistance, surface treatment with halogens, low monomer viscosity, low cost and good availability of the monomer, low outgassing, and is readily machineable. In addition, we propose to develop a new fiber reinforcement approach using Vapor Grown Carbon Fibers (VGCF). These fibers are micron sized, are extremely strong, and have high thermal conductivity. Because they can be easily mixed with polyDCPD, manufacturing can be simplified as compared with conventional fiber reinforced manufacturing. The high thermal conductivity means that composite parts will be very useful for high temperature and ablative structural applications such as for heat shields and rocket nozzles.
