Abstract
A current limiter device comprises at least two electrodes; an interlocked-array electrically conductive composite material disposed between the electrodes; interfaces disposed between the electrodes; an inhomogeneous distribution of resistance at the interfaces whereby, during a high current event, adiabatic resistive heating at the interfaces causes rapid thermal expansion and vaporization and physical separation at the interfaces; and means for exerting compressive pressure on the electrically conducting composite material. The interlocked-array electrically conductive composite material comprises an interlocked-array of spaced apart discrete regions of at least one insulating flexible material and at least one electrically conductive composite material. A method for forming the interlocked-array electrically conductive composite material structure is also set forth by the invention.
