Summary
Wear-resistant composite materials based on polymer binders and products made from them characterized by high deformation and heat resistance, ensuring the stability of the given factor and friction torque in a wide range of loads and sliding speeds in friction units of technological equipment of various purposes, first of all, used in the production of metal cord, textile fabrics, synthetic and mineral fibers. Scientific developments in the area of wear-resistant polymer composite materials with polymeric fluorine matrix for tribotechnical application.
Description
It is supposed that the result of the project will be
adoption of the technology of production of wear-resistant composite
materials on the polymer matrix and various details of tribotechnical
application for friction units of technological equipment used for the
production of yarns and fibers. The composites differ in structure,
including the type of polymer binder used as a matrix. Composites can
be used both in stationary (snub) and at non-stationary (braking or
torque transmission) friction modes. Developed wear-resistant composite
materials are characterized by high deformation strength, which makes
it possible to use them effectively under the conditions of prolonged
exposure of static and dynamic loads.
Due to the high stability of
the friction factor and, consequently, the friction torque, high
stability of fiber tension during the process of winding, unwinding,
the formation of multiple fiber cord, etc. is provided. This is a
prerequisite for obtaining high-quality fiber products. The level
stability and the stability of vibration amplitude of the dynamic
tension of fibers in a wide range of adjustable speed; the optimal
temperature balance of the friction pair allowed by the sanitary code
noise levels in industrial premises, as well as relatively high
wear-resistance in "dry" friction conditions and during the work in
liquid media, including corrosive ones (alkalis, acids) contributes to
the improvement of product quality and ensuring the necessary
technological parameters.
If necessary, during the development of
new composites or adjustment of any properties of the used materials
all R&D will be implemented as part of the project. The basis of
the current technology consists of know-how dealing with both the
structure of the composite material and technologies of its production
and processing.

Technology type
Technical advantages and economic benefits
Technical advantages of the developed wear-resistant
composite materials based on polymer binders are the ability to control
the friction factor on metal surfaces in the range of 0,20-0,46;
increasing the durability in 1,5 times, in the increasing of the Vicat
softening temperature in 1,2 times, in the increasing of damping
capacity (loss factor and dynamic modulus of elasticity), and,
ultimately, in the increasing of the service life of parts in 1,3-1,5
times in comparison with the currently used analogs. Thermal stability
of composites is up to 753 K.
The advantage of the proposed
technology is a low energy intensity of the process of obtaining parts
(in 1,2 times) by reducing the heat treatment time and the possibility
of cooling after heat treatment in normal atmospheric conditions,
availability and universality of applied equipment.
Wear-resistant
materials make it possible to increase the service life of the friction
units and improve the environmental safety while using polymer
composites in enclosed space, since they do not contain any substances
which are harmful to health and environment, which use is restricted or
prohibited, as well as to lower levels of vibration and noise at the
friction units by 4-6 dBA.
