Armoring Panel Edge Impact Resistance via 3D Stratum Ties
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Laminate composite armoring panels fail to effectively resist penetration by ballistic projectiles when struck at the edge, as kinetic forces cause delamination of the strata, reducing their ability to suppress penetration.
Innovation Solution
The armoring panel is designed with its outermost stratum continuing over the edge to form an innermost stratum, and subsequent stratums also extending over the edge, creating delamination-resistant tie sections that function as suspension ties to counteract delaminating forces, using a bonding matrix to interconnect the stratums and a durable sheet with lateral extensions and tie sections to anchor and resist delamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If laminate composite armoring panels are constructed with stacked fabric layers interconnected by adhesive matrix, then the panel achieves structural integrity and penetration resistance, but the panel becomes vulnerable to delamination and penetration when struck at the edge
Solution Approach 1:
The patent extends the stratums beyond the panel's lateral edges into a third spatial dimension, creating tie sections that wrap around and reconnect with opposite edges. This dimensional extension transforms the traditional 2D layered structure into a 3D continuous structure, preventing delamination at edges by providing out-of-plane reinforcement paths that maintain structural integrity during edge strikes
2Weight of stationary object
If the panel stratums are terminated at the lateral edges for material efficiency, then weight and material usage are reduced, but delamination occurs at the edges under ballistic impact
Solution Approach 1:
The patent applies different structural configurations to different regions of the panel: the central region maintains traditional terminated stratums for material efficiency, while the edge regions feature extended tie sections that wrap around and reconnect. This local differentiation provides delamination resistance precisely where needed (at edges) without unnecessarily increasing weight across the entire panel
3Reliability
If the outermost stratum is extended over the edge to form the innermost stratum, then delamination resisting tie sections are created, but the panel complexity increases
Solution Approach 1:
The extended stratum configuration serves multiple functions simultaneously: it provides delamination resistance at edges, creates tie sections for structural continuity, and maintains penetration resistance across the panel. This multi-functionality reduces the need for separate edge reinforcement components, thereby managing complexity while achieving enhanced reliability
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration enhances the panel's ability to resist projectile penetrations at the edge by canceling delaminating forces, preserving the suppression capability of the panel and preventing unwanted penetration, while also offering cost and weight savings through materials-saving void structures.
Implementation Method 1
within an interstitially disposed hardened adhesive or resin matrix, such matrix interconnecting the fiber fabric layers
Implementation Method 2
the portions of such outermost/innermost stratums which span across and overlie the panel's lateral edge surfaces advantageously function as suspension ties which directly resist and cancel delaminating forces
