## Abstract

An armor plate is provided having a lamination of an embedded reinforcement basalt fiber mesh within a laminated cast metal alloy; and at least two layers of an aramid fiber. A process to make the armor plate can include suspending a basalt weave within a mold; heating aluminum 6061 or 7075 alloy to a molten state; pouring the molten aluminum into the mold; cooling the resultant matrixed aluminum to ambient temperature; and laminating at least two layers of ballistic fiber to the matrixed aluminum.

## Claims

### Claim 1

A method of making an armor plate comprising the steps of: suspending a basalt weave within a mold; heating aluminum 6061 or 7075 alloy to a molten state; pouring the molten aluminum into the mold; cooling a resultant matrixed aluminum 6061 or 7075 alloy to ambient temperature; and laminating at least two layers of ballistic fiber to the matrixed aluminum to form a laminate.

### Claim 2 (depends on 1)

The method of claim 1, wherein the aluminum 6061 or 7075 alloy is heated to about 1,400 degrees Fahrenheit.

### Claim 3 (depends on 1)

The method of claim 1, wherein the laminate further comprises the step of vacuum infusing an elastic resin to seals all seams of the laminate.

### Claim 4 (depends on 1)

The method of claim 1, wherein the step of suspending a basalt weave within a mold uses caplets.

### Claim 5 (depends on 1)

The method of claim 1, further comprising the step of spraying the armor plate with a blast mitigation and protective coat in a single coating.
