This project's purpose is to determine the viability of mathematically modeling the load transfer properties of uninterrupted variable cell blanket structures. Variable cell blanket sandwich panel technology integrates varying density areas into a laser welded expanded honeycomb core structure without the need for costly core splicing. The fully integrated varying cell blanket configuration creates an uninterrupted load transfer from one cell size to another. This effort will consist of the physical testing and mathematicaly modeling of the properties of samples of laser welded titanium honeycomb core in a variety of cell sizes, and foil thicknesses. It is anticipated that a viable approach to the modeling of variable cell blanket structures will be developed. This approach will be the model used in designing low cost titanium sandwich panel fabrications. Variable cell blanket sandwich panels offer reduced weight, lower cost and higher strength over other fabricated panel structures. NASA and the aerospace industry will benefit for this improved structural design concept. Complex aircraft designs requiring both low weight and strength can utilize this technology to stay within their design parameters.
