Heat-Resistant Electrical Insulating Fiberglass Plastics for Shipbuilding

Abstract

Abstract—Heat resistance of fiberglass plastics depends mostly on heat resistance of the polymer matrix (binder) and technological modes of production. Increasing the heat resistance and strength of electric insulation makes it possible to improve the properties of electric machines and prolong their working life. Hot pressing technology was developed and fiberglass plastic articles for electric insulation of parts of the ship propulsion complex (main and servicing diesel generators, turbo generators, electric motors) were manufactured. Exploitation modes were settled for electric insulation from different types of binders and reinforcing materials based on alkali-free, quartz, and siliceous high modulus and high strength glass fibers.
