These materials are made by hot pressing and pyrolyzing a mixture of carbon fibers and resin blends. However, the properties of C/C-SiC composites are strongly influenced by their fabrication process, which impacts the microstructure, porosity, and density of the material.One approach to enhance the performance and properties of C/C-SiC composites is to adjust the processing parameters of the manufacturing process. In this study, we will employ the warm-pressing and in-situ reaction method to fabricate C/C-SiC composites and evaluate their friction and wear performance under various operating conditions.Research Objectives:The main objectives of this study are:1. To prepare C/C-SiC composites via the warm-pressing and in-situ reaction method using different carbon fibers and silicon carbide precursors.2. To characterize the microstructure, porosity, and density of the C/C-SiC composites using scanning electron microscopy (SEM) and X-ray diffraction (XRD).3. To evaluate the friction and wear properties of the C/C-SiC composites using a pin-on-disc tribometer under different sliding speeds, loads, and temperatures.Methodology:The following methodology will be employed in this study:1. Manufacturing of C/C-SiC Composites:We will use a warm-pressing and in-situ reaction method to prepare C/C-SiC composites. Carbon fibers will be impregnated with a resin blend containing a silicon carbide precursor such as...
