一、前言 现在,在材料使用方面,对材料的要求是非常广泛的,因而已不太可能用一种材料来满足结构物所需要的使用要求。过去常为特定的结构物选择适当的材料,现在已有可能成型适当的复合材料来满足结构物所希望的性能要求,所谓复合材料就是由几种性能不同的材料组合起来,使其具有组份材料的各自优良性能,有时有些性能还可超过组份材料的性能。近代的层合板、钢筋混凝土更是广泛使用的复合材料。近四十年来,由于航空工业和其他工业的要求,在设计、制造高效能复合材料上更有了相当的进展。 现代复合材料之一的玻璃钢(玻璃纤维
I. INTRODUCTION Nowadays, in terms of material use, the requirements for materials are very extensive, and it is therefore not possible to use a material to meet the requirements for the use of the structure. In the past, often selecting the right material for a particular structure, it is now possible to form a suitable composite material to meet the desired performance requirements of the structure. The so-called composite material is a combination of several materials with different properties, making it a component. The respective excellent properties of the material, and sometimes some properties can also exceed the performance of the component materials. Modern laminates and reinforced concrete are widely used composite materials. In the past four decades, due to the requirements of the aviation industry and other industries, considerable progress has been made in designing and manufacturing high-performance composite materials. One of the modern composite materials of glass fiber (glass fiber
