LASCOR Panel Evaluation and Implementation Phase II

LASCOR process

The Navy Metalworking Center (NMC) led the effort to transition LASer-welded corrugated-CORe (LASCOR) metallic sandwich panels to future Navy applications. LASCOR is a stiff, lightweight and modular steel structure that offers corrosion resistance, reduced weight and less distortion.

Because of the superior technical performance and the competitive cost of this technology, LASCOR is currently being used to develop DDG 1000 Deck Edge Safety Berms and Personnel Safety Barriers for General Dynamics Bath Iron Works and Northrop Grumman Shipbuilding–Gulf Coast.

LASCOR technology is estimated to have significantly reduced the Navy’s overall acquisition procurement cost based on increased competition and a low-cost solution.

The NMC project was recognized for optimizing the LASCOR design for materials, manufacturability, joining, structural and protection performance and cost, as well as successfully manufacturing large (78 x 240-inch) LASCOR panels of CRES 2003, a lean duplex stainless steel from Allegheny Ludlum.

Testing has shown that these panels provide enhanced strength, protection and corrosion resistance. Other potential LASCOR applications being investigated for implementation include decks, bulkheads, covers, doors, ramps and other structural applications.

LASCOR project team members included the Office of Naval Research, Concurrent Technologies Corporation, Bath Iron Works, Applied Thermal Sciences, Northrop Grumman Shipbuilding, Naval Surface Warfare Center Carderock Division, Naval Sea Systems Command and the Institute for Manufacturing and Sustainment Technologies.

Advanced Low Observable Coatings Program

Advanced Low Observable Coatings Program Example

High performance coatings require concise thickness control at the nanometer/micron thickness . Current batch processes for these coatings are prohibitive in cost and throughput to support transition. Unfortunately, no manufacturing process previously existed to prepare these films based on metals, ceramics and polymers on a continuous industrial scale.

The fundamental element of the Advanced Low Observable Coatings (ALOC) facility is its ability to deposit nanolayer films using either vapor deposition or reactive sputtering on a roll 72” wide and up to 5,000 ft long. This is complemented by a 72” wide liquid roll coater capable of depositing polymer films as thin as .2 micron (200 nanometer). For the lightweight paints these thin films are removed from a carrier film and broken up in a thin film recovery station. The resulting thin film particles are further processed by drying, grinding, sizing, color blending, and final quality assurance.

These pigment particles are then loaded into the base polyurethane paint and sprayed using standard spray equipment. The resultant paints weigh up to 35 percent less than the baseline polyurethane formulations. The 35 percent weight savings over conventional paints is expected to result in billions of dollars in life cycle cost savings due to this weight reduction.

ALOC Process

During the ALOC program, investments were made to enhance the capabilities in several major areas related to production of advanced thin film coatings. ManTech made capability enhancements that included: increased web speeds, increased product quantity without increased deposition time for roll width, greater throughput and higher capacity for the thin film recovery equipment, greater cross web thickness control, and UV cured polymers for the liquid roll coating process.
