一、前言复合材料不仅可以提供简单的板材和棒材,而且可提供象飞机的机翼、船体、旅社的接送车等包括焊接件在内的整体构件。因此,复合材料是根据构件的实际需要而设计的材料。如果没有构件的设计,就不能体现复合材料的真正价值。所以复合材料的设计,就是把部件的性能要求作为材料的常数数值化,掌握对应材料常数的原材料的特性并利用该常数进行设计。另外,为了使之成为工业材料,还必须考虑降低成本。本文在考虑以上因素的基础上来介绍复合材料的 I. INTRODUCTION Composites not only provide simple sheets and bars, but also provide integral components, including welding parts, such as the wing of an aircraft, the hull, shuttle buses for hotels, and the like. Therefore, the composite material is designed according to the actual needs of the components. Without the design of the component, the true value of the composite can not be demonstrated. Therefore, the design of composite materials, that is, the performance requirements of the components as a constant value of the material, master the characteristics of the material corresponding to the material constant and the use of the constant design. In addition, in order to make it an industrial material, cost reduction must also be considered. This article takes into account the above factors based on the introduction of composite materials
