Kv. Ermolaev et al., PULSED NQR TECHNIQUE FOR MEASURING INTERNAL-STRESSES IN CURED EPOXIDES, Vysokomolekularnye soedinenia. Seria A, 40(10), 1998, pp. 1715-1719
A pulsed NQR technique capable df measuring internal stresses in cured
epoxides (epoxy compounds) is described. Conditions for using cuprous
oxide particles as a pressure indicator were studied. The results of
the NQR measurements of internal stresses in compounds based on an epo
xy oligomer (EKhD, ED-20) cured with poly(ethylene polyamine) are pres
ented.
