Electrically driven technologies are replacing hydraulic, pneumatic and mechanical systems in new military aircraft designs to improve capability, reliability and maintainability. This transition requires high performance electronic components capable of operating over a wide temperature range. Capacitors, which provide necessary power conditioning, have been identified as a limiting component for these architectures. New dielectric materials and capacitor designs are needed to provide high specific capacitance and operation at high temperature. TPL completed a successful Phase I program to address this need and demonstrated fundamental proof-of-feasibility for a capacitor design using a novel dielectric film technology. A high dielectric constant film based on fluorinone polyester (FPE) polymer modified with titanate nanopowder was developed. Thermal and electrical performance characteristics of the FPE nanocomposite and packaging materials support a significant advance in high temperature capacitors. The Phase II will focus on incorporating the FPE nanocomposite film into capacitors using industry standard manufacturing techniques. Successful completion of the proposed program will result in a novel capacitor technology that addresses the Air Force’s need for compact power conditioning modules in advanced aerospace weapons systems. Capacitors will be fabricated with FPE nanocomposite film and packaged to provide high volumetric capacitance (>1.0 ìF/cm3) and operation from -55 to 300°C at 150 kHz.
