一、序言碳/碳复合材料作为一项新型材料,大约在一九五八年开始问世了。最初出现的这种材料是用树脂反复浸渍然后碳化的办法制得的。大约在1965年才出现化学气相沉积的碳/碳复合材料。十余年来这种材料有很大发展。研究这种材料主要目的在于宇航方面的应用,如作为再入热防护和火箭喷管等。这种材料在航空工业方面作为 I. INTRODUCTION As a new type of material, carbon / carbon composites began to come out in about 1958. The first such material was made by repeatedly impregnating the resin and then carbonizing it. Approximately 1965 chemical vapor deposition of carbon / carbon composites occurred. More than a decade of great development of this material. The main purpose of studying this material is in aerospace applications, such as reentry thermal protection and rocket lances. This material is used in the aviation industry
