研究了抗氧化涂层及工艺对碳／碳复合材料弯曲性能的影响，结果表明，涂覆后的材料强度略有降低，但幅度不大，涂层工艺使材料层间结合强度增大是引起弯曲强度下降的主要原因。 The effect of anti-oxidation coating and technology on the flexural properties of carbon / carbon composites was studied. The results show that the strength of the material after coating decreased slightly, but the amplitude was not large. The increase of bonding strength between the layers resulted from the coating process Bending strength decreased the main reason.
