Composite Isogrid Structure

This program creates the design of alight weight, composite, load bearing superstructure for surface ships. The program is supported by Bath Iron Works (BIW) as a Navy Ship contractor. BIW will supply details of structural loading and impact requirements. WCT will design an isogrid reinforced panel structure to accept the loading conditions. Mounting requirements for components are examined and the isogrid system geometry is developed and modeled. Mounting inserts are evaluated for pullout loads and environmental conditions. Pro Engineer and Laminate Design modeling techniques are used to confirm the design. Test data from an existing DOD contract will be used to support mounting design. Panels are closed out with composite skins, one face by co-curing, the other by bonding. Carbon foam will be considered as a fill medium within the isogrid core. This will enhance the bond strength to the closeout skin and provide enhanced strength to the panel. The option program will cover design, fabrication and test of a prototype composite panel. In addition to structural testing, the component attachment system will be tested. Test results are evaluated and an optimum panel design and mounting system are created, leading into a Phase II program.
