DESIGN AND DEVELOPMENT OF COMPOSITES BASED ON BASALT/CERAMIC FIBERS FOR HIGH TEMPERATURE APPLICATIONS

Textile Engineering

Composite materials for high-temperature applications are advanced materials composed of two or more distinct constituents, typically a matrix and reinforcing fibers, designed to withstand elevated temperatures while maintaining structural integrity. These materials offer superior strength, thermal stability, and corrosion resistance, making them crucial in industries like aerospace, automotive, and energy for components exposed to extreme heat and stress. This innovative approach focuses on creating composite materials using nano-filled epoxy resins, specifically tailored for aeronautical structural components. These materials not only provide effective lightning strike protection but also enhance their thermal stability. The epoxy matrix is formulated by blending a tetrafunctional epoxy precursor with a reactive diluent, reducing moisture content and facilitating the dispersion of nano-fillers. This diluent not only aids in better distribution but also accelerates the curing process of the epoxy mixtures, ultimately increasing their structural integrity and thermal resistance compared to epoxy alone. The primary objective of this research is to investigate and analyze the mechanical characteristics such as tensile strength, impact strength, strain, hardness, wear resistance, and fatigue properties of two types of composites: 100% Basalt fabric epoxy composite and 100% Ceramic fabric epoxy composite. The study involves varying different parameters to assess the mechanical attributes. Additionally, the research aims to assess the mechanical properties of Basalt and Ceramic fabric epoxy hybrid composites with varying blend ratios. Following the development and testing of these mechanical properties, the research evaluates the performance of these composites in high-temperature applications. This assessment is carried out through finite element analysis, and the results are compared with an existing composite product designed for high-temperature use.
