The process of curing an epoxyamine composite was investigated by methods of dynamic mechanical analysis and rotational viscometry. The service characteristics of the cured composites depend on the curing process and are directly related to the process kinetics and to change in the rheological characteristics.

Standard methods were used to investigate the physicomechanical characteristics of the main parts of endotracheal tubes produced by six leading world manufacturers. It was shown that the articles have statistically significant, substantial differences in the physicomechanical properties of their main working units: the main tube and the sleeve. The sleeve is the least strong part on which the functionality of the entire article depends. The best strength characteristics are possessed by the Curity sleeve, but at the same time the Curity main tube possesses practically no thermal plasticity. The Rush main tube possesses high thermal plasticity but has the least strong sleeve. Most balanced from the viewpoint of physicomechanical characteristics is the Portex tube. Having sufficient tube elasticity and strength, among the investigated tubes it has the highest thermal plasticity with minimum hardness at body temperature and a sleeve of high strength.

A study was made of the effect of thermoplastic modifiers on the kinetics of curing of the epoxy binder. The kinetic and diffusion constants of the curing process were determined.

A study was made of the effect of different nanofillers on the viscosity of an epoxy composite obtained using mechanical mixing and ultrasound.
