NCMS has made available 5 project technical reports for purchase.

Heat Transfer Classification for Production Tooling and Composite Repairs
– This project is leading to a paradigm shift in the approach to the autoclave curing of composite parts. Improvements in computer power and sensors now enable higher quality composite manufacturing, and greatly reduced scrap as well. This project developed and tested tools to manage heat transfer for ovens and autoclaves used in the production and repair of composites.

Integration of Laser Coating Removal for Helicopter Blade Refurbishment – Phase II
– The primary objectives in Phase II were to overcome scale-up and technical integration issues and to deliver an operational ARBSS for test, evaluation, and eventual production. This report summarizes the work conducted under the Phase II effort summarizing the design requirements and overall system design, then provides details of the laser workhead, the integrated robotic system, and the user interface.

Thermal Processing of Aluminum Alloys
– The purpose of the project was to develop a software tool capable of predicting the distortion, residual stress state and microstructural phases for heat treated aluminum alloys. The feasibility of using a predictive software for 7075 aluminum part heat treatment design was successfully demonstrated.
*This report is open to the public.

Validation of Functional Trivalent Chrome Plating Process – Phase II & IIA
– Traditional chromium plating releases a mist of highly corrosive droplets that pose a risk to process operators. Hexavalent chromium has been implicated in long-term health effects, including cancer. In Phase II, an extensive series of tests was performed on samples produced using Faraday’s trivalent chrome process. The samples were able to successfully pass several key tests and performed comparably to hexavalent chrome. In Phase IIA encouraging results were achieved by modifying process plating parameters and select tank additives, a potential increase in platable current density range.

*This report is available to NCMS members only, the public release date is February 2014.

Ultra-Lightweight Sandwich Composite Constructions for Autobody Applications
- The purpose of the R&D effort was to develop strategies for sandwich composite construction technologies for significant weight reduction for automotive applications and to develop computationally efficient models to predict the behavior of sandwich composites using model-based brokerage portals. Identified glass fiber composite/balsa core sandwich composites and their processing methods for automotive applications in stiffness critical applications.

Project Final Report: Enhanced Wiring Integrity Systems

Project findings are presented from the Enhanced Wiring Integrity System (EWIS) Project. The wiring system is the infrastructure that links electrical, electromechanical and electronics subsystems. Wiring is truly a critical system that requires new maintenance tools and processes.

Project objectives were to implement a single or common test system to provide solutions that: are applicable to the joint services – Navy, Air Force, Army, and Marines; reduce the work-hours expended troubleshooting and repairing materiel electrical wiring systems; and increase the reliability of materiel with preventive and predictive maintenance.

The EWIS project provided improved commercially-available test systems to enhance the troubleshooting and testing capabilities of the maintainers and ultimately improving the overall integrity of electrical wiring systems. The user-friendly product is in use at multiple DoD sites.

The Process Substitution Methodology project for composite materials provided immediate benefit to the Department of Defense (DoD) war fighting capability during missions in Afghanistan, Kosovo and Iraq.

The primary goal of this project was to develop and install the basic tools required to support material state management approach upon which the substitution methodology is based. The rapid revision of the processes that allowed for expansion of the Predator mission is just one example of potential applications. The material state management approach provides production personnel and support engineers with visibility on the effects of changes in process of the composite.

A variety of landing gear components are failing without having reached their desired service lives. The failures are due primarily to stress corrosion cracking (SCC) and fatigue. The objective of this project was to improve the fatigue life and SCC resistance through the application of laser peening technology to selected components.

Team members on this project were the Aging Landing Gear Life Extension Program (ALGLE) at Ogden Air Logistics Center, the Lawrence Livermore National Laboratory (LLNL), the University of California (Davis), and the Metal Improvement Company. The project was funded and managed through the National Center for Manufacturing Sciences (NCMS) Commercial Technologies Maintenance Activities (CTMA) program.
