Abstract
Abstract A method of making an incendiary munition and product utilizes a quasi alloy zirconium or titanium type incendiary material which is formed either as an inner liner or outer liner of the shell of the munitions body by use of heat and pressure. When used as an inner liner the incendiary material may be engraved by use of a molding process to determine the explosive particulate pattern and fragmentation size of the munition. With proper location of the material in a HEAT warhead it will be ingested into the penetrated unit.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
91 words
A method of making a munition with a flowable incendiary material comprising a mixture of epoxy and powdered metal including the following steps: cleaning a surface of the munition; and solidifying and bonding said incendiary material to said surface by the use of sufficient heat and pressure such material being bondable by said heat and pressure to said surface to maintain structural integrity between said munition surface and said incendiary material to prevent the separation of said material from said surface during the occurrence of setback during firing of the munition.
Claim 2
Independent Claim
91 words
A method of making a munition with a flowable incendiary material comprising a mixture of epoxy and powdered metal including the following steps: cleaning a surface of the munition; and solidifying and bonding said incendiary material to said surface by the use of sufficient heat and pressure such material being bondable by said heat and pressure to said surface to maintain structural integrity between said munition surface and said incendiary material to prevent the separation of said material from said surface during the occurrence of setback during firing of the munition.
Claim 3
Dependent Claim
47 words
A method as in claim 1 where said surface is interior to the body of said munition and including the step of pouring said material into said body and applying said pressure by a ram, said incendiary material being formed with a uniform density without significant voids.
Claim 4
Dependent Claim
19 words
A method as in claim 2 where said ram is engraved and forms a predetermined pattern in said material.
Claim 5
Dependent Claim
37 words
A method as in claim 2 where a pressure of 1,000 psi is applied by said ram at a temperature of 300° F. for a time period of 10-40 seconds depending on the thickness of said material.
Claim 6
Dependent Claim
30 words
A method as in claim 1 where a significant portion of said powdered metal consists of one or more elements from group IV B of the periodic table of elements.
Claim 7
Dependent Claim
11 words
A method as in claim 5 where such element is zirconium.
Claim 8
Dependent Claim
11 words
A method as in claim 5 where such element is titanium.
Claim 9
Dependent Claim
12 words
An incendiary munition made in accordance with the method of claim 1.
Claim 10
Independent Claim
117 words
A method of providing high velocity incendiary fragments by use of a metal shell casing and an incendiary material comprising an epoxy and powdered metal mixture, comprising the steps of, bonding said material to a portion of said casing to maintain structural integrity between said munition surface and said incendiary material to prevent the separation of said material from said surface during the occurrence of setback during firing and to maintain such integrity during exploding, and thereafter exploding said shell casing and igniting said incendiary material to provide a plurality of metal fragments each having a burning incendiary material thereon such burning material providing an increased back pressure for reducing the coefficient of drag of said fragments.
Claim 11
Independent Claim
117 words
A method of providing high velocity incendiary fragments by use of a metal shell casing and an incendiary material comprising an epoxy and powdered metal mixture, comprising the steps of, bonding said material to a portion of said casing to maintain structural integrity between said munition surface and said incendiary material to prevent the separation of said material from said surface during the occurrence of setback during firing and to maintain such integrity during exploding, and thereafter exploding said shell casing and igniting said incendiary material to provide a plurality of metal fragments each having a burning incendiary material thereon such burning material providing an increased back pressure for reducing the coefficient of drag of said fragments.
Claim 12
Dependent Claim
33 words
A method as in claim 9 including the step of engraving said incendiary material and where in said exploding step said shell casing and bonded incendiary material fragmentate in accordance with said engraving.
