Patent attributes
A fiber composite material which is particularly suitable for aircraft construction, includes inorganic mineral fibers embedded or enclosed in a metal matrix. The mineral fibers include a substantial or dominant proportion of SiO2, and/or Al2O3 and/or Fe2O3, the remainder being rock material. The fibers have a length of at least 10 mm and are oriented in parallel to one another in at least one direction. The metal matrix is made of aluminum, aluminum alloys, magnesium, magnesium alloys, titanium or titanium alloys. These matrix metal alloys contain a substantial or dominant proportion of the respective metal. The fibers are preferably coated with particles of the matrix metal and bonded to one another to form fiber films or fiber sheets which are then laminated between sheets of matrix metal.
