Romenska O. Carbon plastics for thin-walled rocketry-space structures

The dissertation is devoted to solving an important scientific and technical problem - improving the strength characteristics of carbon plastics for thin - walled structures of rocket and space technology by developing and using new methods of processing raw materials - carbon fiber and epoxy binder. In the work of increasing the strength characteristics of carbon fiber based on carbon fiber УКН/5000 and epoxy binder Huntsman was performed by treating the surface of the filler with high-energy plasma streams in the environment of precursors: acrylic acid or allylamine. A comprehensive study of the surface layer of carbon УКН/5000 fibers both traditional and plasma-treated in the environment acrylic acid or allylamine, using electron microscopic analysis, infrared, X-ray photoelectron and Raman spectroscopy (Raman scattering). Definitely the wetting angles of the epoxy matrix of the filler in the initial state and after modifying treatment. Based on research, it is established that processing carbon fiber УКН/5000 plasma in acrylic ACID leads to an increase in the strength of carbon fiber, and the use of infrared heating can further improve the performance material during the intensification of the technological process of manufacturing products and reducing energy consumption.
