摘要采用有限元法分别建立碳纤维束微观结构模型和2.5D碳纤维织物增强碳基复合材料单胞结构模型,计算稳态热边界条件下的碳纤维束等效热导率和碳基复合材料等效热导率,研究碳纤维直径和单丝间距对碳纤维束轴向、径向热导率及碳基复合材料沿厚度方向热导率的影响。结果表明,基体碳的热导率介于碳纤维的径向热导率和轴向热导率之间;纤维束横截面积一定时,随碳纤维直径增大,纤维束轴向热导率升高,径向热导率降低,碳基复合材料沿厚度方向热导率降低;随单丝间距增加,纤维束轴向热导率降低,径向热导率升高,碳基复合材料沿厚度方向热导率升高。

Abstract：The microstructure model of carbon fiber bundles and the unit cell structure model of the composites reinforced by carbon fiber with 2.5D fabric were established by finite element method. The equivalent thermal conductivity of carbon fiber bundles and composites in steady thermal conditions were calculated. The effects of carbon fiber diameter and the space between two carbon fibers on the thermal conductivity in axial and radial direction of carbon fiber bundles and in thickness direction of the composites were investigated. The results show that, the thermal conductivity of the carbon matrix is between the radial thermal conductivity and the axial thermal conductivity of carbon fiber. With increasing the carbon fiber diameter, the axial thermal conductivity of the carbon fiber bundles increases, the radial thermal conductivity and the thermal conductivity of the composites in thickness direction decrease. With increasing the space between two carbon fibers, the axial thermal conductivity of the carbon fiber bundles decreases, the radial thermal conductivity and the thermal conductivity of the composites in thickness direction increase.
