Research of methods of obtaining continuous fibres of whiskers

Abstract

The object of this research is some methods of obtaining continuous fibers of whiskers. The method of obtaining such fibers by extrusion of an organometallic colloidal solution is studied using the example of a scheme for carrying out such process. The process of obtaining fibers by the method of pyrolysis of polymeric fibers is studied using the example of another conceptual scheme. The problematic aspects of carrying out both processes and the use of such methods include the difficulty in obtaining the desired configuration and orientation of the fibers of threadlike crystals, as well as the inadequate perfection of the apparatus and installations for obtaining such fibers. When writing the work, various methods of scientific research were used, such as the method of statistical analysis, the method of analyzing the research results, the hypothetico-deductive method and the method of generalizing the results. The conducted studies show that the conditions for carrying out both processes must be strictly controlled, especially the temperature rise. It is shown that the methods used have an increased degree of danger. It is substantiated that, in spite of observance of all parameters of the conducted processes, the fact that the final fibers of the crystals will not have the necessary orientation and configuration may not be ruled out. As a result of the studies it is shown that the production of continuous fibers of whiskers by extrusion of an organometallic colloid solution is quite effective from the point of view of obtaining the final product of the desired orientation and the necessary parameters. The effectiveness of this method can be improved if the processes of doping the fibers from the gas phase are successfully used. It is shown that when carrying out studies of obtaining similar fibers by pyrolysis, it is possible to have high efficiency of the completed process, with full observance of the parameters of its conduct and sufficient perfection of the equipment. A fairly significant issue when using this particular method is the most effective conduct of the tension process of continuous fibers of whiskers during the heat treatment.
