Current Projects

  • R&D (3)_BorderIntegrated Corrosion Detection System

LPT is working on a Navy Phase 2.5 SBIR project (N68335-07-0283) to develop a handheld optical sensor for early detection of corrosion underneath paint.  This effort has produced the LPT-S2 Sub-coating Inspection Instrument.

 

  • Fiber Coupled Corrosion Control System

LPT has begun an Air Force SBIR Phase II project to produce a prototype fiber-coupled corrosion control system, which provides corrosion detection, paint removal, corrosion cleaning, corrosion repair, and process monitoring in difficult to access areas without damaging the underlying substrate or adjacent features.  This system was conceptually designed and experimentally demonstrated in Air Force SBIR Phase I project FA8117-14-C-0010.

 

 

 

 

 

 

 

 

 


 


Previous Research


  • Monitoring Electron Beam Freeform Fabrication by Active Machine VisionR&D (9)_Border

LPT has completed a NASA SBIR Phase I project (NNX14CL71P) to develop an advanced active machine vision system for improving the metallic additive manufacturing process of Electron Beam Freeform Fabrication (EBF3) to provide spatial, temporal, spectral and thermal information of the melt pool as well as material compositions.

 

  • Surface Modification by Ultrafast Laser Irradiation

Supported by the NASA-Langley Research Center, LPT used ultrafast laser pulse interaction with metal surfaces leading to formation of self-organized conical micro/nano structures in various metals including Ti, Al, Cu, and stainless steel.

 

  • Laser Removal of Composite Coatings and Damaged Areas

LPT has completed a Navy Phase I project (N68335-12-C-0016) to develop a laser-based method of safely and quickly removing material on the surface of composites without compromising the structure.

 

  • Aluminum and composite micromachining

A process to produce a precise laser notch formation was developed for fatigue testing of aluminum plates and cylinders. Laser micromachining was applied to fiber reinforced polymer composite cutting.  This effort was supported by the NASA-Langley Research Center.
