Abstract

This invention uses a variable density liner for shape charges to create unique and beneficial explosion properties. To create the variable density (either radially, axially, or in the transverse direction), additive manufacturing is used. Materials with different densities are applied in a specific pattern to create the engineering variable density.

Title:  Method and Apparatus of Shape Charge Design with Variable Density Liner

Abstract:  This invention uses a variable density liner for shape charges to create unique and beneficial explosion properties. To create the variable density (either radially, axially, or in the transverse direction), additive manufacturing is used. Materials with different densities are applied in a specific pattern to create the engineering variable density.

Description:  Additive manufacturing (3D metal printing) is used to build up the profile of a shape charge liner but using several different materials. This creates certain sections with different material properties. With different materials properties in the liner, the shape charge jet can be modified and optimized for performance in different formation types.  This process could possibly be done by hand but without any significant confidence in repeatability. With additive manufacturing, the process of liner manufacturing is 100% repeatable. Since liners are very delicate, current manufacturing processes are limited. In the current process metal powder is pressed into a conical shape. Additive manufacturing would build the conical shape, allowing for delicate and precise part geometries.   This invention is unique ability to create a variable density part by additive manufacturing. This would be difficult with other known manufacturing processes.
