Due to the strong effect of the composite fabrication method on the structural capacitor performance, the structure development should be performed with the involvement of composite engineers. Structural development should be conducted with inclusion of the electrical contacts in the overall design.
The modification of a structure to render the capacitor function involves the positioning of a dielectric film between the electrodes, which are an electronic conductor, commonly the continuous carbon fiber laminae that serve to reinforce the composite.
The fundamental design parameters available to the designer are controlled to a large degree by the environmental factors, such as temperature range, voltage, wave shape, pulse repetition rate (rep-rate), and duty cycle. Essentially all these environmental factors affect the life expectancy of the capacitor as shown schematically in Figure 2 .
There is also a certain comfort level among engineers at the capacitor manufacturer with working with materials they know and whose reactions they have come to understand over decades of trial and error. It is for this reason that the investments in the existing dielectrics have created the most value for the shareholder over time.
The production of electric field results due to the insulating nature of the dielectric material keeping the charges separated, which allows the capacitor to store energy.
7. CONCLUSIONS Modern capacitor technologies generally retain the potential for increased power and energy densities by factors of 2-10 times, depending upon the specific technology.

A capacitor is a simple device. It is basically just two conductors sandwiched with an insulator between them. Engineers know the basic laws of physics: capacitance (the amount of charge) increases directly with the area of the conductors (plates), inversely with their distance apart, and directly with the dielectric constant of the insulation. Given a moment to …
