前言现在,炭纤维增强碳复合材料(c/c已广泛地用作诸如航空、航天材料等高温结构材料。在这些应用中,纤维的各种性能(热膨胀、热容、导热性等)对复合材料的设计都是非常重要的性能。可是,在一般温度下取得这些性能的数据很少,尤其是在300℃或400℃以上的纤维热膨胀行为几乎没有报 Preface Nowadays, carbon fiber reinforced carbon composites (c / c) have been widely used as high temperature structural materials such as aerospace, aerospace materials, etc. In these applications, various properties (thermal expansion, heat capacity, thermal conductivity, The design of materials is a very important property, but few data are available for these properties at typical temperatures, with little evidence of thermal expansion at 300 ° C or above
