本文是关于美国碳/碳喷管材料近况的综述文章。原文没有作者,所以也没有出处,标题是我们自己加上的。本文是我国的一位专家从国外带回的一位美国教授整理的资料。我们在内容和文字上做了些精减,但据我们对美国碳/碳喷管材料现状的了解,这是一篇较为难得的材料。对于从事碳/碳材料研究的人员,可以较为真切地了解多维编织,浸渍碳化复合工艺的动向;对于使用碳/碳材料的设计人员也许可以从中吸取一些对设计工作有益的经验。将碳/碳复合材料成功地用于固体火箭喷管设计是一个很复杂的问题。这种碳/碳复合材料的特性是:在复合过程中,它要经受相似甚至大于火箭发动机工作时间的应力应变;因此进行喷管热结构分析时,要求充分熟悉这种复合材料是怎样制备的,此外,由于材料的基本组分因部位而异,也足以严重影响预测结构合理性的置信度等。本文介绍了为解决上述问题,多年未进行的相关的逻辑的成果。在所提及的三个主要项目中,阐述了其工业生产能力和最新的技术水平。这三个项目是:生产与质量保证;烧蚀预测与控制;结构设计与分析。最后又按这三大项的分类,或按其适用范围的方式,对本文提出的问题的各个方面作出总的评价。 This article is a review article on the state of the art of carbon / carbon nozzle materials in the United States. The original author, so there is no source, the title is our own plus. This article is an information collected by an American professor brought back by an expert from China. We have done some refinement in content and text, but based on our understanding of the current state of carbon / carbon nozzle materials in the United States, this is a relatively rare material. For people engaged in carbon / carbon materials research, you can more truly understand the multi-dimensional braided, impregnated carbide composite process trends; for designers of carbon / carbon materials may be able to draw some from the design work useful experience. The successful use of carbon / carbon composites in the design of solid rocket lances is a complex issue. The characteristics of this carbon / carbon composite are that it undergoes stress-strain similar to or even greater than the working time of the rocket engine during the compounding process; therefore, thermal structural analysis of the nozzle requires full familiarity with how the composite is prepared In addition, since the basic components of the materials vary from part to part, it is enough to seriously affect the confidence of the reasonableness of the forecast structure. This article describes the results of the relevant logic that has not been carried out for many years to address the above issues. Among the three major projects mentioned, their industrial capacity and the latest technological level are described. The three projects are: Production and Quality Assurance; Ablation Prediction and Control; Structural Design and Analysis. Finally, according to the classification of these three items, or according to the scope of its application, this article presents a general assessment of all aspects of the problem.
