| Summary: | The paper presents the results of studies of composite
materials based on epoxy resins with different types of
filling are considered. It is shown that a material with a
metal filler has higher mechanical characteristics compared
to a material filled with ceramics. The material retains
high mechanical properties at low temperatures and after
interaction with petroleum products. Hydraulic tests showed
that the material with a ceramic filler withstood only on
non-through defects. The metal-filled material has passed
the tests for non-through defects and through defects at
pressures up to 4,0 MPa. The material with a filler based
on Fe and Cr powder can be used in pipeline construction
for temporary repair of valves with non-through defects or
through defects of valves operating up to 1,6 MPa. |
