据美刊[轻金属时代]1989年第4期报道,DWA复合材料特殊制品公司宣布:第一种大量生产的新的Revlite(商品名)金属基复合材料,正在用于制造洛克希德飞机上的电子设备支架. 以前,这些支架是用7075-T 6铝合金挤压件制造的,用新的金属复合材料代替它可以将支架的重量减轻17%,因为新材料的刚性高65%. 新的支架安装在飞机上后进行了一年多的飞行鉴定.在用来替换7075-T 6铝合金的候选材料中还有石墨环氧树脂,因为它不导电(导电性是这种用途的一个重要特性,因为该支
According to the U.S. publication [Light Metal Times], Issue 4, 1989, DWA Composites Special Products Company announces that the first new mass-produced Revlite (commodity name) metal matrix composites are being used to manufacture Lockheed aircraft These brackets were formerly made of 7075-T 6 aluminum alloy extruded parts, and replacing it with a new metal composite material can reduce the weight of the brackets by 17% because of the 65% higher rigidity of the new material. The aircraft was installed on the aircraft for more than a year after flight qualification. There was also a graphite epoxy in the candidate material used to replace the 7075-T 6 aluminum alloy because it was not electrically conductive (conductivity was an important aspect of this use Characteristics because of the branch
