碳纤维是一种比较理想的材料。它的比强度和比刚度大(比强度是钢的8倍、铝的6倍、钛的5倍,比刚度是钢的5.5倍、铝的6倍);抗疲劳性能和减振性能好;磨擦系数小,耐高温;成形工艺好。因此,近年来,美、英、日、西德等航空界组织了专门机构研究这种材料,使之应用于航空工业。做法是先在老机种上选择一些能显著减轻重量、危险性小、研究费用少,或者即使有一定危险性但收益较大的零部件,从中总结设计、工艺、使用等方面的经验,然后再在新机中逐步推广。为了叙述方便,现把碳纤维复合材料在国外航空工业上的应用情况,归纳成如下几个方面简单地谈一谈。 Carbon fiber is a more ideal material. Its specific strength and specific stiffness (than the intensity of steel 8 times, 6 times the aluminum, titanium 5 times, the rigidity is 5.5 times the steel, aluminum 6 times); fatigue resistance and vibration damping performance; Small friction coefficient, high temperature; forming process is good. Therefore, in recent years, the aviation community in the United States, Britain, Japan, West Germany and other aviation circles has organized specialized agencies to study such materials so that they can be applied to the aviation industry. The practice is to first select some old models can significantly reduce the weight, the risk of small, research costs less, or even if there is a certain risk but greater returns of parts and components, from the summary of design, technology, use, etc. experience, and then Then gradually promote the new machine. In order to facilitate the narration, now the carbon fiber composite materials in the aviation industry in foreign countries, the application summarized as follows briefly talk about.
