以碳素材料微观结构与表面形貌为基础,研究了不同型号的碳/碳复合材料及石墨材料的光谱发射率。研究表明,石墨微晶结构规整度与表面微观形貌是影响碳素材料光谱发射率差异的因素。为评价碳素热辐射性能、设计高效热场提供理论指导。
In this work,on the basis of carbon materials microstructure and morphology,the radiation properties of different type of carbon/carbon composites and graphite materials was studied.The results show that the graphite crystal structure regularity and surface morphology of carbon materials is the main factor of difference in spectral emissivity.It could provide theoretical guidance to evaluation of thermal radiation performance of carbon materials and design efficient thermal field.
