A METHOD FOR MAKING A COMPOSITE METALLIC MATERIAL COMPRISING THE STEPS OF: (A) SIZING AND SHAPING A PLURALITY OF SHEETS OF METAL SELECTED FROM THE GROUP CONSISTING OF ALUMINUM TITAMIUM AND THEIR ALLOYS, EACH SHEET HAVING A TOP FACE AND A BOTTOM FACE; (B) PRODUCING IN THE TOP FACE OF EACH OF THE PLURALITY OF SHEETS A PLURALITY OF ALIGNED SUBSTANTIALLY PARALLEL GROOVES SUCH THAT ADJACENT GROOVES DO NOT JOIN ONE ANOTHER; (C) PLACING IN EACH OF THE GROOVES A REINFORCING MEMBER, A WIRE, FIBER OR FILAMENT SELECTED FROM THE GROUP CONSISTING OF BORON AND BERYLLIUM, HAVING A DIAMETER OF ABOUT 0.001-0.01" AND A LENGTH-TO-DIAMETER RATIO GREATER THAN 20; (D) STACKING THE PLURALITY OF SHEETS ONE UPON THE OTHER SO THAT THE REINFORCING MEMBERS IN TOP FACE OF EACH SHEET ARE POSITIONED OPPOSITE THE BOTTOM FACE OF THE NEXT ABOVE OF THE PLURALITY OF SHEETS; AND THEN (E) PRESSING THE PLURALITY OF SHEETS ONE TOWARD THE OTHERS WITH A PRESURE OF ABOUT 1000-10,000 P.S.I. WHILE AT THE SAME TIME HEATING THE SHEETS AT A TEMPERATURE OF 800-1500*F. IN A VACUUM TO INTEGRALLY BOND THE SHEETS ONE TO THE OTHER AND TO INTEGRALLY BOND THE REINFORCING MEMBERS TO THE SHEETS.
