"A detailed scientific image of the manufacturing process of ceramic matrix composites (CMCs) through liquid silicon infiltration (LSI). Show the various phases of the process. In the first step, a porous carbon fabric or a fiber- reinforced structure (preform) is depicted, into which liquid silicon is infiltrated. The infiltration is shown through a high- temperature process where the silicon penetrates into the pores. The silicon then reacts with the carbon to form silicon carbide (SiC), which forms the ceramic matrix. Depict the final CMC with the fiber- reinforced structure combined with the newly formed SiC matrix. Pay attention to the textural differences between the original carbon fabric, the silicon infiltration, and the resulting silicon carbide matrix. The scene should be scientifically accurate, with a clear focus on the high- temperature furnace, the reaction between carbon and silicon, and the final structure of the CMC material. "
