Keywords: Measuring Stiffness of Soft Polymers (5940488395).jpg NIST researchers developed a new high-speed method for measuring the stiffness of soft-polymer materials like those used in contact lenses The test material is covered with a sensor film and the combination is compressed until it buckles The resulting pattern of ridges is the key to determining stiffness an important material property Courtesy of National Institute of Standards and Technology Disclaimer Any mention of commercial products within NIST web pages is for information only; it does not imply recommendation or endorsement by NIST Use of NIST Information These World Wide Web pages are provided as a public service by the National Institute of Standards and Technology NIST With the exception of material marked as copyrighted information presented on these pages is considered public information and may be distributed or copied Use of appropriate byline/photo/image credits is requested https //www flickr com/photos/usnistgov/5940488395/ Measuring Stiffness of Soft Polymers 2006-06-22 10 42 https //www flickr com/people/63059536 N06 National Institute of Standards and Technology PD-USGov National Institute of Standards and Technology https //flickr com/photos/63059536 N06/5940488395 2016-09-07 02 36 25 United States Government Work Uncategorized 2016 December 20 |
