Rapid product design of improved ballistic articles
A method for the design and development of new ballistic resistant articles is provided. Improved ballistic articles are formed of polyethylene-based composite laminated structures having unique material properties including material density, Poisson's ratio, and modulus of elasticity (Young's modulus). Cycle time for completing design and development is less than 30 calendar days.
1. A method for a rapid design of improved ballistic articles comprising, in combination:
identifying new armor products or existing armor products to be improved upon;
creating a 3D engineering model utilizing ballistics failure analyses with a CAE (Computer Aided Engineering) program utilizing an anti-ballistic material comprising:
interlineated layers of modified polyethylene materials; and
layers of carbon nanotubes between adjacent modified polyethylene materials layers, wherein each said interlineated layer of modified polyethylene material is formed having a molecularly oriented layer of material;
iteratively testing said 3D engineering model until a suggested design is achieved to meet a selected specification;
creating a physical prototype of said suggested design; and
destructively testing said physical prototype to confirm if the selected specification is achieved;
wherein the CAE (Computer Aided Engineering) program is utilized with the 3D engineering model imported into a stand-alone simulation application for said iterative testing of the 3D engineering model to modify material properties selected from a group comprising: material density; Poisson's ratio; and modulus of elasticity (Young's modulus).
