Effect of Low Temperature on Mechanical Properties of Bidirectional Glass Fiber Composites

Abstract

In this article, low temperature and its degradative influence on the material together with hygro-thermal effect are highlighted. Hygrothermal factor is a major environmental factor experienced by the composites. An attempt has been made to study the mechanical properties of bidirectional glass cloth specimens exposed to low temperature and humid condition. Tensile strength records its highest value after 10 days exposure at -55°C, compressive strength at 0°C exposure increases but after 10 days exposure at -55°C decreases, shear strength of exposed specimen at 0°C increases, flexural strength of exposed specimen at -55°C increases and records its highest value of 10 days exposed specimen. Further, it has been observed that the strength of the composite is in the following order: Compressive strength of specimen<shear strength of specimen<tensile strength of specimen<flexural strength of specimen. In this article an attempt has been made to study effect of low temperature on mechanical properties of bidirectional glass fiber composites.
