dc.description.abstract© 2020, Pleiades Publishing, Ltd.Abstract: Borosiloxane as a functional layer in multilayer self-healing composites is studied. The provisions and principles of self-healing in artificial materials are considered. It is substantiated that rapid self-healing requires at least two factors: directional mass transfer and self-adhesion of the boundaries brought into contact. Either fluid media or viscous-flow materials may act as self-healing materials. Borosiloxane is presented as a promising material of a self-healing viscous matrix in multilayer composites or sandwich panels. The addition of various fillers, e.g., fibers, to borosiloxane leads to a decrease in fluidity; owing to the low molecular weight, high diffusion of macromolecules ensuring high self-adhesion is maintained. The addition of polyester fibers to borosiloxane makes it possible to effectively control fluidity with the high diffusion rate and consequently the coalescence rate of the material surfaces brought into contact being maintained. Experimental samples of borosiloxane are obtained from synthetic rubbers during their interaction with boronic acid in a heated reaction vessel. The addition of 6 wt % polyester fibers ~3 mm long to the synthesized borosiloxane confines its spreading, preserves its shape owing to the stiffness of the fiber framework, and at the same time retains the properties of self-adhesion while the disconnected boundaries are brought into contact. The creation of ensembles from successive borosiloxane layers with different fluidity in one multilayer material allows providing the final composite material with high self-healing characteristics after a penetration defect is made. The effect of self-healing of the developed layered composite in the case of through puncture and cut is shown.
