Abstract
Abstract A composite material having greater strength to density and modulus to density ratios than existing monolithic materials comprises a titanium alloy having either beryllium wires or beryllium wires having a titanium cladding or wrapping for reinforcement. In forming the composite, laminates of titanium alloy sheets are explosively welded to beryllium wire reinforcement or titanium clad or wrapped beryllium wire reinforcement by stacking the laminates in layers with the wires placed between layers and explosively welding the layers and wires together.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
46 words
A COMPOSITE MATERIAL COMPRISING A PLURALITY OF TITANIUM ALLOY SHEETS; AND A PLURALITY OF BERYLLIUM WIRES LOCATED BETWEEN ALL ADJACENT SAID SHEETS AND EXPLOSIVE WELDED TO SAID TITANIUM ALLOY SHEETS FORMING A TITANIUM MATRIX REINFORCED WITH BERYLLIUM WHEREIN SAID BERYLLIUM WIRES HAVE A HELICAL TITANIUM WRAPPING.
Claim 2
Dependent Claim
46 words
A COMPOSITE MATERIAL COMPRISING A PLURALITY OF TITANIUM ALLOY SHEETS; AND A PLURALITY OF BERYLLIUM WIRES LOCATED BETWEEN ALL ADJACENT SAID SHEETS AND EXPLOSIVE WELDED TO SAID TITANIUM ALLOY SHEETS FORMING A TITANIUM MATRIX REINFORCED WITH BERYLLIUM WHEREIN SAID BERYLLIUM WIRES HAVE A HELICAL TITANIUM WRAPPING.
Claim 3
Dependent Claim
25 words
A composite according to claim 1 wherein said wires are substantially parallel to each other and spaced from one to 5 mils from each other.
Claim 4
Dependent Claim
27 words
A composite according to claim 2 wherein said helical titanium wrapping has a thickness from 1.5 to 2.5 mils and a width from 9 to 11 mils.
Claim 5
Independent Claim
126 words
A method of forming a composite material comprising the steps of: assembling a specimen comprising at least two sheets of titanium alloy and at least one intervening layer comprising a plurality of substantially parallel beryllium wires wherein said beryllium wires have a helical titanium wrapping; placing the specimen between a first and second metal plate with said first plate on top of said specimen and said second plate underneath said specimen; placing said specimen and said first and second metal plates on top of a base plate; juxtaposing an explosive on top of said first metal plate; and detonating said explosive so as to weld the specimen together with the materials of the specimen flowing to fill in the spaces formed in the specimen as assembled.
