MECHANICAL PROPERTIES OF GLASS FIBER AND CARBON FIBER REINFORCED COMPOSITES

Abstract

The significant potential of glass fiber-based composite materials in aerospace and aviation industries, automotive manufacturing, and medical equipment production is emphasized. It is concluded that glass fiber is much cheaper and less brittle compared to materials like carbon fiber or other plastic fibers, as glass fiber exhibits high resistance to tensile and compressive loads. The main stages of the technological process of composite manufacturing are described, and the key requirements for evaluating the mechanical parameters of glass fiber products are listed. An analysis of the scientific literature has established that the high strength of fiberglass ensures the stability of its thermal conductivity characteristics, making it resistant to environmental influences and aging. The thermal conductivity of fiberglass composites depends on several factors, the most important of which are the type of fiber and matrix, fiber volume fraction, fiber characteristics, control of heat flow, interaction between the matrix and fiber, and operating temperature. It is summarized that the mechanical properties of fiberglass structures depend on a number of factors, the most important of which are: the type of fiber and resin, fiber orientation (aligned, randomly oriented, woven, etc.), and the percentage content of each component.
