摘要:
高导热碳/碳复合材料具有轻质、高导热、高模量、低热胀以及传统碳/碳复合材料的高温高强度等优异性能，已成为当前复合材料研究的热点，在航天航空、电子科技、核工业等领域具有广阔的应用前景。本文依据构建的典型结构碳/碳复合材料热导率模型，定量分析了重点结构参数对碳/碳复合材料热导率的影响，并据此开展了高导热碳/碳复合材料结构设计、调控、制备与表征研究，制备出室温导热方向热导率分别达到700, 400和350 W/m·K以上单向、二维和三维高导热碳/碳复合材料。
Abstract:
Because of its excellent properties, such as lightweight, high thermal conductivity, high specific modulus, low heat expansibility and all excellent properties of traditional C/C composites, the high thermal conductivity C/C composites (HTC-C/Cs) have become research focus in recent years and have broad application prospect in the fields of aerospace, electronics, nuclear industry and so on. In present study, effects of key structural parameters on the thermal conductivity of C/C composite were quantitatively analyzed based on the analytical model of thermal conductivity, which was defined as a function of the microscopic structure parameters of C/C composite with typical architectural feature. Based on the analysis results, HTC-C/Cs with different textures and dimensions were designed, prepared and characterized. As a result, the thermal conductivities of prepared unidirectional, 2D and 3D HTC-C/Cs were more than 700, 400 and 350 W/ m·K at room temperature, respectively.
