License Rights May Be Issued On An Exclusive Or Nonexclusive Basis And May Include Specific Fields Of Use.nasa Provides No Funding In Conjunction With These Potential Licenses. the Technology: when Testing Composite Structures, It Is Important To Understand The Response Of The Structure To The Load. Of Significance Is The Formation Of Damage And Growth Of That Damage Leading To Ultimate Failure. Understanding How A Structure Fails Allows For Optimal Designs For Improved Safety And Performance For The Part During Its Life Cycle. Inspection Methods Are Required To Determine Damage Initiation And Growth In Advanced Composite Structures During Loading. Past Methods For In-situ Inspection Of Composite Structures During Loading Have Involved Acoustic Emission, Passive Thermography, Digital Image Correlation, And Fiber Optics Techniques. However, Each Of These Has Critical Limitations. The Combination Of Thermal And Acoustic Emission (ae) Nondestructive Evaluation (nde) Techniques, By Mapping The Acoustic Emission Events Onto The Thermal Imagery, Provides A Very Sensitive Measurement System For Detecting Damage Formation And Growth. this Technology Provides A Methodology To Measure Damage Onset And Grow At Multiple Locations In A Composite Structure During Fatigue Loading. The Thermography Inspection Is Non-contact And Can Cover Very Large Areas. The Acoustic Emission Sensors Require Contact At Only The Sensor Attachment Points And Can Cover Large Areas. The Acoustic Emission Measurement Is Very Sensitive To Damage Formation Events Such As Matrix Cracking, Fiber Breaks, And Delamination, However The Event Location Is Approximate. An Infrared Camera Is Able To Detect Damage Growth And Location At Areas Of Heating (due To Fiber Breaks, Rubbing Of Disbond Areas And Matrix Cracks) And Thus Confirm The Acoustic Emission Measurements. If The Loading Is Cyclic The Infrared Camera Is Also Able To Detect The Relative Depth Of The Damage. Combining Both Technologies Helps To Reduce False Indications, Confirm Damage Growth Areas And Where Ultimate Failure Will Occur. This Provides A Measurement Capability To Detect Growing Damage (location And Size) For Improved Structures Testing Or During In-service Applications. Multiple Infrared (ir) Cameras And Multiple Acoustic Emission Sensors Can Be Employed Internally Or Externally For Full Coverage Of The Structure. When Significant Damage Growth Is Detected, The Structure Can Be Taken Out Of Service For Repair Or For Further Inspections. This Technology Has Been Demonstrated For Structures Testing. In-situ Nde Inspections Are Necessary To Provide Structural Engineers A Tool To Incrementally Control And Document Damage Growth As A Function Of Fatigue Cycles Before Failure. This Allows For The Comparison Of Nde Results To Develop And Validate Progressive Damage Analysis (pda) Models. The Ultimate Goal Is To Use The Validated Pda Models To Decrease The Time Required To Certify Composite Structures And Therefore Save Development Costs. Real Time Nde Can Document The Progression Of Damage And Provide The Documentation Of Ultimate Failure Mechanisms. to Express Interest In This Opportunity, Please Submit A License Application Through Nasa’s Automated Technology Licensing Application System (atlas) By Visitinghttps://technology.nasa.gov/patent/lar-tops-247 if You Have Any Questions, Please E-mail Nasa’s Technology Transfer Program Atagency-patent-licensing@mail.nasa.govwith The Title Of This Technology Transfer Opportunity As Listed In This Sam.gov Notice And Your Preferred Contact Information.

License Rights May Be Issued On An Exclusive Or Nonexclusive Basis And May Include Specific Fields Of Use.nasa Provides No Funding In Conjunction With These Potential Licenses. the Technology: innovators At The Nasa Langley Research Center, In Collaboration With Analytical Mechanics Associates, Have Developed An Automated Ultrasonic Scanning System For In-situ Cure Monitoring And Defect Detection Of Composites In An Autoclave Or An Oven. This Non-destructive Evaluation System Is Based On An Ultrasonic Contact Scanner Enclosed In An Insulated Vessel Placed Inside Of The Autoclave. The System Actively Scans For Any Defects That May Form In Composites During The Cure Process And Tracks Movement Of Defects Originating During Layup Or Cure. Typically, Non-destructive Evaluation Of Composites, By Ultrasound Or Other Means, Is Conducted Either Before Or After The Cure Process, But Many Defects Vanish And Form During Cure. Nasa's In-situ Cure Monitoring System, By Contrast, Provides Real-time Monitoring Of Defect Formation And Movement During Cure. This Not Only Offers A Better Understanding Of Defect Sources And Sinks, But Also The Ability To More Accurately Validate Process Models For The Prediction Of Cure Process Defects. nasa's System For In-situ Defect (e.g., Porosity, Fiber Waviness) Detection In Composites During Cure Consists Of An Ultrasonic Portable Automated C-scan System With An Attached Ultrasonic Contact Probe. This Scanner Is Placed Inside Of An Insulated Vessel That Protects The Temperature-sensitive Components Of The Scanner. A Liquid Nitrogen Cooling Systems Keeps The Interior Of The Vessel Below 38°c. A Motorized X-y Raster Scanner Is Mounted Inside An Unsealed Cooling Container Made Of Porous Insulation Boards With A Cantilever Scanning Arm Protruding Out Of The Cooling Container Through A Slot. The Cooling Container That Houses The X-y Raster Scanner Is Periodically Cooled Using A Liquid Nitrogen (ln2) Delivery System. Flexible Bellows In The Slot Opening Of The Box Minimize Heat Transfer Between The Box And The External Autoclave Environment. The Box And Scanning Arm Are Located On A Precision Cast Tool Plate. A Thin Layer Of Ultrasonic Couplant Is Placed Between The Transducer And The Tool Plate. The Composite Parts Are Vacuum Bagged On The Other Side Of The Tool Plate And Inspected. The Scanning System Inside Of The Vessel Is Connected To The Controller Outside Of The Autoclave. The System Can Provide A-scan, B-scan, And C-scan Images Of The Composite Panel At Multiple Times During The Cure Process. The In-situ System Provides Higher Resolution Data To Find, Characterize, And Track Defects During Cure Better Than Other Cure Monitoring Techniques. In Addition, This System Also Shows The Through-thickness Location Of Any Composite Manufacturing Defects During Cure With Real-time Localization And Tracking. This Has Been Demonstrated For Both Intentionally Introduced Porosity (i.e., Trapped During Layup) As Well Processing Induced Porosity (e.g., Resulting From Uneven Pressure Distribution On A Part). The Technology Can Be Used As A Non-destructive Evaluation System When Making Composite Parts In In An Oven Or An Autoclave, Including Thermosets, Thermoplastics, Composite Laminates, High-temperature Resins, And Ceramics. to Express Interest In This Opportunity, Please Submit A License Application Through Nasa’s Automated Technology Licensing Application System (atlas) By Visitinghttps://technology.nasa.gov/patent/lar-tops-327 if You Have Any Questions, Please E-mail Nasa’s Technology Transfer Program Atagency-patent-licensing@mail.nasa.govwith The Title Of This Technology Transfer Opportunity As Listed In This Sam.gov Notice And Your Preferred Contact Information.
