摘　　要：采用高温模压成型法制备环氧树脂/碳纤/BN导热复合材料。探讨了BN用量对复合材料导热性能和力学性能的影响。结果表明,当BN用量为6%(wt)时,复合材料的弯曲强度和剪切强度较佳,BN用量对复合材料的冲击强度影响不大;导热性能随BN用量的增加而增加,当BN用量为20%(wt)时,导热系数为0.8438W/m.K。The epoxy/carbon fiber/boron nitride thermal conductive composites were prepared by compression mould method at high temperature. The effect of BN content on the thermal and mechanical properties of composite materials was investigated. The results showed that the flexure and the shear strength of the composites were optimal with 6% mass fraction of BN. The effect of BN content on impact strength was neglected. The thermal conductivity of the conaposites were improved with the increasing mass fraction of BN, and the thermal conductivity coefficient λ reached 0.8438W/（m＇K） when the mass fraction of BN was 20%.
