Characterization of Mechanical and Viscoelastic Properties of Glass Fibre Reinforced Polymer Composites
Year: 2024
Type: article
Abstract: This study investigates the mechanical and Viscoelastic properties of glass fibre reinforced polymer (GFRP) composites, focusing on improvements in performance due to the incorporation of glass fibres. The GFRP composites were fabricated using E-glass fibres embedded in an SC-15 epoxy resin matrix. Tensile, flexural, and dynamic mechanical analysis (DMA) tests were conducted to characterize the properties of the composites. The results showed a 30% increase in tensile strength and a 25% improvement in elastic modulus compared to neat epoxy resin. The tensile strength of the GFRP composite was found to be 489 MPa, while the modulus of elasticity increased to 24.5 GPa. In flexural testing, the GFRP composites exhibited a 20% increase in flexural strength, reaching 600 MPa, and a 15% improvement in flexural modulus, measured at 22 GPa. Additionally, the dynamic mechanical analysis demonstrated a 40% increase in storage modulus, with the composites maintaining stiffness across a temperature range from 30°C to 180°C. The glass transition temperature (Tg) increased by 10°C, indicating improved thermal stability. These enhancements are attributed to the effective load transfer between the glass fibres and the epoxy matrix, as well as improved fibre-matrix adhesion due to silane surface treatment. This study provides critical insights into the mechanical behaviour and thermal stability of GFRP composites, underscoring their potential for high-performance structural applications, including aerospace and marine engineering.
