Abstract
Improvements in spark plug electrodes, especially wire-shaped central electrodes, intended for spark plugs of internal combustion engines consisting of a fibrous composite material in which in a matrix material of high conductivity for electricity and heat is shown at least one fiber arranged essentially in the longitudinal direction, of the electrode, made of a material resistant to corrosion, a good conductor of electricity and, if possible, also of heat, and surrounded by a shell of material resistant to corrosion, characterized by the fact that the electrode contains between 5 and 50% by volume of copper or a corrosion resistant copper alloy, as the matrix material.
