Abstract

It is known that for decrease in viscosity polymeric binding on the basis of epoxy oligomers in their composition injecting solvents of the different nature and thermodynamic compatibility. In this paper the dependences describing influence on shrinkage, kinetics of increase and maximum level of strains from diluents content and temperature of curing of epoxy oligomers are established. Introduction about 20 % of the active diluents (DEG-1 and SO-3) in system on the basis of epoxy oligomers leads to decrease in viscosity in ~3 times, to improvement of imbibition quality of fibrous fillers, increase of volume contraction (on ~2.5. %) and decrease in residual stresses in ~6 times as a result of increase of mobility of pieces of a polymeric chain in a three-dimensional grid, and also to decrease in glass transition temperature no more than ~20°C.
