THE EFFECT OF VARIOUS METALLIC FILLING MATERIALS
ON THE PROPERTIES OF AROMATIC-POLYAMIDE-BASED
COMPOSITE MATERIALS
Introduction. Nowadays, a number of new materials appear and compete with
traditional ones. Among them, there are three main groups: metals (alloys,
intermetallics, amorphous materials, coatings and films), ceramics (technical
composites or ones with ceramic matrix) and plastics (polymer alloys, polymer matrix
composites, new types of thermoplastics). Back in the 1920s, the basic types of raw
materials used in engineering were aluminum and steel, in the 1940s stainless steel and
plastics were added to them, in the 1950s there were heat-resistant alloys and titanium,
in the 1980s there were composite materials, refractory metals and ceramics. Over the
years, the main indicators on which they were chosen were also changed. In the 1920s
these indicators were strength and cost, in the 1940s the requirement of resistance to
corrosion was added, in the 1950s there were the temperature resistance and fatigue
strength, and in the 1980s there were the resistance to creep and mass [1]. Today, the
main criteria for choosing substitute materials are the relative cost and cost in view of
durability, corrosion resistance, strength, manufacturability and so on.
The modern needs of the national economy in new materials are growing rapidly,
new and higher requirements are being imposed on them, and scientists are faced with
the task of creating materials that have a number of specific properties. The increased
urgency of the problem is connected, firstly, with the continuous development of the
design of machines and mechanisms in the direction of increasing the mechanical and
thermal strength of their mobile connections; secondly, with the importance for the
national economy of increasing durability, because this causes not only a reduction in
depreciation expenses, but also an increase in the fleet of operating machines [2].
A perspective direction to solve the problem of increasing the durability and
ensuring the reliability of structures operating under conditions of erasure effects in
any friction nodes is their manufacture from special polymeric composite materials
(PCM), which combine high wear resistance and strength with the necessary structural
properties. Such PCMs include composites obtained by introducing dispersed metal
particles into the polymer environment. As a result of the chemisorption interaction of
