September 2014 - May 2016
NSRP ASE Investment: $435K
Industry Investment: $435K
Objective:
To qualify, in conjunction with NAVSEA, adhesive design rules and application guidelines that will apply to all surface combatants and expand the range of applications for adhesive outfitting.
Summary:
During the course of this project the team sought to expand applications for adhesive outfitting beyond specifically tested and approved items by developing design rules for adhesively bonded studs. The rules followed NAVSEA criteria for the use of adhesives and were based on tests conducted by the project team to establish allowable loading based on failure modes. Initial consideration was given to lightweight items weighing less than 100 pounds using adhesives and mounting hardware with documented performance. The design rules took into consideration all applicable NAVSEA requirements and the team identified any changes to ship specifications required for implementation.
Currently, adhesive mounting approvals require each item to be individually tested for shock and vibration performance. While this approach may allow an initial set of items to be qualified, it was not feasible to perform individual qualification tests for each item that could be mounted with adhesive bonding. The project characterized the load limits of adhesively bonded studs so that general design rules could be qualified.
The first phase of this project included the development of technical requirements and test plans for expanded applications of adhesive outfitting. The second phase executed NAVSEA approved test procedures and developed the design rules for expanded applications.
