去年Martin Marietta Composites公司发货创公司纪录的12件工程,总计2900m~2。其中2/3已安装好,而剩余部分将于2002年初安装。MMC的复合材料面板技术/产品DuraSpan~(TM)是由连续的玻璃纤维和间苯聚酯树脂的基体组成。选用DuraSpan~(TM)于构架桥和升降式桥是因为受荷载限制、常用材料的严重腐蚀和磨损。轻质高强的复合材料桥面板使现有的上层结构能支承现行的设计荷载而只需进行少量的附加工作。此复合材料桥面板设计得非常耐
Last year, Martin Marietta Composites shipped 12 records of the company’s construction projects, totaling 2900m ~ 2. Two-thirds are installed and the rest will be installed in early 2002. MMC Composite Panel Technology / Products DuraSpan ™ is composed of a continuous matrix of glass fiber and m-phenylene terephthalate resin. The use of DuraSpan ™ for framed and bridge is due to load limitations, severe corrosion and wear of commonly used materials. The lightweight, high-strength composite decking allows existing superstructures to support existing design loads with minimal additional work. This composite deck is designed to be very resistant
