Influence of cryogenic treatment on mechanical behavior of glass fiber-reinforced plastic composite laminate

Abstract

Composites are the modern trend materials replacing monolithic metals and alloys in many industrial applications. It has also been widely used in many of engineering applications where materials are subjected to very low temperatures. Hence it finds essential to investigate its mechanical properties after cryogenic treatment of composite materials and compare the results with behavior of materials at ambient conditions. This chapter describes the preparation of glass/epoxy composites for different volume fraction. The developed specimens were subjected to cryogenic treatment with the aid of liquid nitrogen. Mechanical properties such as tensile, impact, and flexural behavior were presented separately of cryogenic treated specimens and untreated specimens. The obtained results exhibited enhanced mechanical properties.
