Abstract

The methodology for creating composite materials based on polymer matrices for the manufacture of special-purpose structures such as an injector for the introduction of drugs into the human body under extreme conditions is considered. An original design of the injector for use in special conditions has been developed, which is distinguished by the efficiency of repeated use. For the manufacture of functional structural elements, composite materials based on industrial thermoplastics – polyamides (PA6) and polyolefins (HDPE) were used, including modifiers of structural characteristics of various composition, structure and production technology – chitosan and Na + -montmorillonite clay treated with organocomponents. Structural, thermophysical, stress-strain, rheological parameters of composites containing functional modifiers have been studied. To ensure the homogeneity of the distribution of dispersed modifier particles, a polyamide resin based on rosin and a polycondensation product of adipic acid and diethyleneamine was used. The effect of increasing the parameters of the stress-strain characteristics of composites, due to the processes of reinforcement and the formation of adsorption bonds between the particles of the modifier and the active centers of macromolecules, has been established. At the same time, the rheological parameters of composite materials provide the possibility of manufacturing injector elements by injection molding. The design of the injector using composite materials has a pronounced bactericidal effect, which increases its consumer characteristics in special conditions of use.
