New centrifuge technology will enable multi-sample adhesive and composite strength testing
A new analytical centrifuge is being used to test adhesive bonds, coatings and composites. BAM Federal Institute for Materials Research and Testing’s scientists had the idea that samples should no longer be clamped, but simply inserted. Simply inserting the specimen makes rapid loading poss ... more
