Resistance and modulus reinforcing materials

Abstract

This invention relates to new composite materials having, along a director plane, noteworthy mechanical properties, wherein they comprise a resistant material, in flat form disposed parallel to the director plane and flakes or bands or substantially flat form, constituted of or comprising a material with high modulus, said flakes or bands also being disposed parallel to the director plane.

What is claimed is: 
     
       1. A composite material having improved mechanical properties comprising, a resistant material, a reinforcing material with high modulus and a matrix material, said resistant material is flat, disposed parallel to a director plane and is selected from the group consisting essentially of steel, titanium, nickel and alloys thereof, said high modulus reinforcing material is selected from the group consisting essentially of boron, silicon carbide, titanium boride, aluminium diboride and magnesium diboride, said high modulus reinforcing material being in the form of flakes or bands and disposed parallel to the director plane. 
     
     
       2. The composite material as defined in claim 1, wherein the matrix is of a material which provides good cohesion between the resistant material and the high modulus material. 
     
     
       3. The composite material as defined in claim 1, wherein the resistant material is titanium, the reinforcing high modulus material is silicon carbide flakes, said composite material is prepared so that a physicochemical interaction develops between the titanium and the silicon carbide. 
     
     
       4. The composite material as defined in claim 1, wherein the resistant material is titanium, the reinforcing material is a band comprising a silicon carbide surface and a core selected from the group consisting essentially of molybdenum and titanium, said composite material is prepared so that a physicochemical interaction develops between the titanium of the resistant material and the silicon carbide.
