1 前言 近年来碳纤维、硼纤维利玻璃纤维加环氧树脂等制成的复合材料已深入国民经济各个领域,这是由于复合材料制成的薄壳结构既轻巧又牢固。目前我国用复合材料制成的薄壳在造船、航空、锅炉制造以及钢筋混凝土屋顶中得到广泛的应用。有鉴于此,对正交异性极扁薄壳结构的力学性能的研究,具有重大的实用价值。
1 Introduction In recent years, composite materials made of carbon fiber, boron fiber, glass fiber and epoxy resin have penetrated into all aspects of the national economy due to the light weight and firmness of the thin shell made of composite material. At present, the shell made of composite materials in our country is widely used in shipbuilding, aviation, boiler manufacturing and reinforced concrete roof. In view of this, the research on the mechanical properties of the Orthotropic thin flat shell has great practical value.
