摘要：
The shear strength of unidirectional epoxypolysulfone glass-reinforced plastics in the range of six decimal orders of loading rates has been measured. ED-22 epoxydiane resin (analog of DGEBA) modified by PSK-1 aromatic polysulfone served as a matrix. It has been shown that the strength values linearly increase with increasing logarithm of the loading rate; the sensitivity of composites to the rate of application of a force increases with increasing quantity of PSK-1 introduced into the matrix, and the fracture mechanism of composites is the thermofluctuation one. The laws revealed do not differ from those established by us earlier for glass-reinforced plastics based on epoxy binders modified by active diluents. © 2005 Springer Science+Business Media, Inc.
