摘要
炭/炭复合材料在航天与航空工业有广泛应用前景。本文研究了2D炭/炭复合材料结构与性能的关系。结果表明,2D炭/炭复合材料的力学性能和热物理性能与它的密度有密切关系.在同样密度条件下。2D炭/炭复合材料的性能与微观结构有重要联系,球团状结构的性能较片层状结构的性能差,抗拉强变降低了约58％,抗拉模量降低了约63％。
Carbon-carbon composites have been found wide perspective for application in astronautic and aeronautic industries. In this paper a 2D carboncarbon composite was systematieally studied with the emphasis on the relationship between their structures and properties. It was found that the mechanical and thermophysical properties of the 2D carbon-carbon composite are closely related to the densities. On condition that the densities are same the properties of the 2D carbon-carbon composite are tied up with microstructures. The properties of the 2D carbon-carbon composite with accumulated granules structure are lower than those with laminar structure. The tensile strength reduces by 58％ and tensile modulus decreases by 63％.
