前言碳纤维或石墨纤维材料是近年来研制成功的一种新型材料。由于它具有高的机械强度、高的有效烧蚀热、高刚性、低比重、耐高温等特性,所以用它制造的各种复合材料广泛地用于导弹、火箭和飞机的重要结构和烧蚀部件。因此,对碳纤维材料进行热重 Preface Carbon fiber or graphite fiber material is a new type of material developed successfully in recent years. Because of its high mechanical strength, high effective heat of ablation, high rigidity, low specific gravity, high temperature resistance and other properties, the various composites made from it are widely used in the important structures and ablation of missiles, rockets and aircraft part. Therefore, the thermal carbon fiber material weight
