Simplified Hybrid Stanchions and Tough Puncture Proof Inflatable Airbags for Navy CLF Ships and Over-The-Road Transport

KaZaK Composites proposes to develop and implement improvements to current CLF and over-the-road wood dunnage systems by designing and prototyping two key items of the system, a cost effective adjustable stanchion and a toughened composite modular air bag. Key requirements for a redesigned dunnage system include elimination of wood, ability to support structural loads, significant reduction in total ownership costs, ease of repair for system components, light weight, ease of use, and ability to withstand rough handling. Adjustable stanchions will be designed to meet and/or exceed existing load requirements, reduce stanchion weight, withstand environmental conditions (hot, cold, wet), take rough handling and meet fire performance specifications. An integrally stiffened composite air bag structure will meet mechanical load requirements and eliminate blocking assemblies. Proposed dunnage systems will not impact current restraint systems/operations or require costly ship modifications. By engaging both the over-the-road systems and CLF ship systems, KaZaK and the Navy are insured that developing designs will be compatible, effective and, where applicable, interchangeable. In Phase I, KaZaK will perform extensive design trade studies, including finite element analysis of critical load conditions, followed by fabrication and testing of key sections of dunnage hardware to validate performance predictions.
