Abstract
Dyneema (R) and glass fiber reinforced plastics (DGFRPs) expand when they a re cooled down to cryogenic temperature. Therefore, they may have applicati ons as structural materials in superconducting magnets to increase stabilit y against abrupt motion of superconductors in the magnets. To obtain the me chanical properties of DGFRPs, we measured coefficients of friction on surf aces of DGFRPs under various experimental conditions at three temperatures. four different forces, and two types of DGFRPs. In all of the experimental conditions, the measured coefficients of friction were quite low. The rang e of measured coefficients was 0.07-0.14. (C) 2001 Elsevier Science Ltd. Al l rights reserved.
