摘要

Carbon fiber-enhanced silicon carbide (Cf/SiC) is a superior ceramic-reinforced composite distinguished by its low density, elevated hardness, remarkable specific strength, and superior wear resistance. Due to these superior properties, it finds broad applications in the advanced engineering fields, including space mirrors, aircraft engines, and brake systems. Precision grinding significantly diminishes the surface roughness of 2D-Cf/SiC composites while maintaining surface integrity. This research establishes a microsimulation model of two-dimensional braided carbon fiber-reinforced silicon carbide to elucidate the grinding mechanism. A prediction model for grinding forces in 2D-Cf/SiC composites was developed using single and multiple abrasive grain grinding experiments. The empirical verification of the grinding force model was subsequently conducted. The data reveal that the absolute difference between forecasted and experimental values is consistently less than 10%, hence affirming the model’s accuracy and reliability. This study offers valuable insights for enhancing the grinding process of 2D-Cf/SiC composites.
