一、前言炭素材料的机械性质包括弹性性质,其大多数对结构具有敏感性。炭素材料一般可分为玻璃炭、天然石墨、热分解炭、人造石墨、炭纤维等许多种类,其结构也多种多样,这些全都在其机械性质上有所反映。但是,无论那一种情况,其基本结构都是六方晶 I. INTRODUCTION The mechanical properties of carbon materials include elastic properties, most of which are structurally sensitive. Carbon materials can generally be divided into many types of glassy carbon, natural graphite, pyrolytic carbon, artificial graphite, carbon fiber and so on, and its structure is also varied, all of which are reflected in its mechanical properties. However, in either case, the basic structure is hexagonal
