POLYMER COMPOSITE MATERIALS BASED ON PHENOLIC
MATRIX WITH DISCRETE ORGANIC FIBERS
Introduction. The rapid development of technics and new technologies currently
makes stricter requirements to the operational characteristics of polymer composite
materials. At the beginning of the XXI century, annual growth in output of PCM was
10-16 % in industrialized countries. Construction materials based on polymer and
reinforced by chemical and mineral fiber fillers are widely used in modern aviation and
space technologies, shipbuilding and engineering, mining, metallurgical, agricultural
and other industries. They have significant advantages in comparison with such
traditional materials as steel, bronze, aluminum, titanium alloys, babbitt and
widespread PCM textolites and rubber. PCM are characterized by high physico-
mechanical and tribological properties, they are able to operate in highly loaded friction
units of various mechanisms. They have good thermo-insulating and sound-absorbing
properties. In addition, they are efficient in dusty environments, in water and other
aggressive liquids.
PCM do not need traditional oil greasing, that’s why it is possible to solve the
environmental problem (as the level of water pollution is significantly reduced) while
using them in shipbuilding, building of hydraulic turbines, where mechanical seals are
made of them. One of the main factors providing a significant economic effect by using
antifriction PCM is save on unscheduled repairs of equipment connected with
premature failure of friction units, because the service life of PCM details 2-5 times
exceeds in comparison with traditional materials. PCM do not only successfully replace
traditional structural materials, but are also able to work in conditions excluding the
use of metals [1]. Products of PCM are easy to produce and replace during equipment
repairing, they do not often require greasing. The properties of PCM are determined by
