- Description
- NASA�s Technology Transfer Program solicits inquiries from companies interested in obtaining license rights to commercialize, manufacture and market the following technology.� 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: In the polymer composites industry, cure cycles are typically developed from a trial and error or a more effective processing science approach to reduce the final porosity level in the composite laminate. Using an automated system, high-temperature piezoelectric transducers were utilized to interrogate a twenty-four ply unidirectional composite panel fabricated from Hexcel IM7/8552 prepreg during cure.� It was shown that the amplitude of the guided wave increased sharply around vitrification and the TOA curve possessed an inverse relationship with degree of cure. A guided wave-based in-process cure monitoring technique for carbon fiber reinforced polymer (CFRP) composites was investigated at NASA Langley Research Center.� A key cure transition point (vitrification) was identified and the degree of cure was monitored using metrics such as amplitude and time of arrival (TOA) of guided waves.� Using the technique to perform in-process cure monitoring in an autoclave, defect detection during cure, and a closed-loop process control to maximize composite part quality and consistency enables a significant improvement in non-destructive evaluation, which could lead to fabrication process improvements. To express interest in this opportunity, please submit a license application through NASA�s Automated Technology Licensing Application System (ATLAS) by visiting https://technology.nasa.gov/patent/LAR-TOPS-271 If you have any questions, please contact Langley Research Center at LARC-DL-technologygateway@mail.nasa.gov with the title of this Technology Transfer Opportunity as listed in this FBO notice and your preferred contact information.� For more information about licensing other NASA-developed technologies, please visit the NASA Technology Transfer Portal at https://technology.nasa.gov/ These responses are provided to members of NASA�s Technology Transfer Program for the purpose of promoting public awareness of NASA-developed technology products, and conducting preliminary market research to determine public interest in and potential for future licensing opportunities.��No follow-on procurement is expected to result from responses to this Notice.
