Carbon fiber reinforced carbon matrix composites(C/C)have the advantages of low density,high specific strength,high specific modulus,and performance that does not decrease but rises with temperature.They are mainly used in aircraft thermal protection systems and engine high-temperature and anti-ablation components in the aerospace field.However,with the cross generational development of high-tech weapons and equipment,C/C composites face bending strength less than 300 MPa,severe high-temperature oxidation and ablation during application The difficult problem of high cost requires modification in areas such as high performance,ultra-high temperature resistance,long lifespan,and low cost.This article reviews the research progress and future development trends of C/C composite material modification in China,providing ideas for the modification research of C/C composite materials in areas such as high performance,ultra-high temperature resistance,long lifespan,and low cost.
