The influence of an electric field on the hardening process, 
the structure, and the properties of an epoxy composite in the presence 
of a phosphorus-containing carbon filler has been investigated. It 
has been shown that under the action of an electric field the process 
of formation of a three-dimensional epoxy polymer in the presence 
in the system of phosphocarbon fibers proceeds more intensively with 
the formation of a more rigidly bound structure of the polymer as 
compared to the same composition hardened in the absence of the field. 
It has been established that the fibrous filler-binder interface 
has a dominant role in the formation of a spatially cross-linked polymer 
and in the properties of the product hardened both under the action 
of the electric field and without it.
