Abstract

Investigating the behavior of fiber/polymer composite structures and the effect of various factors on their mechanical properties is vital in defining the design, manufacturing and troubleshooting process. In this paper, the changes in the mechanical behavior of the E-glass fiber/polyester composite structure under the influence of thermal preloading on the glass fiber fabric have been studied. For this purpose, in addition to performing mechanical tests, scanning electron microscopy (SEM) has been used to investigate the manner and nature of glass fiber breakage as well as the cross-sectional area of fiber fracture. Also, the changes in the state of the bonding agent on the surface of the glass fibers used in the woven fabric, in the initial conditions of as received fabric and also in its secondary conditions after applying thermal preload by placing it in an oven at 350 °C temperature was studied. In this regard, the Attenuated Total Reflectance (ATR) infrared spectroscopic analysis method was used. The results indicate a significant decrease in the mechanical properties of the manufactured composite, as a result of applying thermal preloading on plain fabric made of E-class glass fibers, before the impregnation stage with unsaturated polyester resin.
