一、工程复合材料发展展望 1.从结构工程发展的回顾看复合材料的发展桥梁工程发展水平的表征——桥梁的最大跨度建筑工程发展水平的表征——建筑物的高度这除了反映工程技术水平的发展外,更带基础性的因素是新材料的发展: 十九世纪八十年代中期熟铁的发展——桥梁最大跨度三百多米; First, the prospects for the development of composite materials 1. Review of the development of composite materials from the structural engineering development Characterization of the level of development of the bridge project - the maximum span of the bridge Characterization of the level of development of the building - the height of the building This reflects in addition to engineering level The more fundamental factor is the development of new materials: the development of wrought iron in the mid-1980s - the largest span of bridges is over 300 meters;
