复合材料世界网站2016年4月21日刊文称,埃尔比特系统公司旗下龙卷风公司采用一次性树脂转移模塑(RTM)工艺,开发了一款没有使用金属紧固件的全复合材料飞机舱门。龙卷风公司报道其成功验证了舱门设计的制造,使用的是自有专利的几何锁定的复合材料附件,实现了完全没有紧固件的结构,对比现在使用的铝和“黑铝”复合材料舱门,减重和成本达到30%。 Composites World Web Site April 21, 2016 The article said Elbit Systems Inc.’s Tornado Company has developed a one-off resin transfer molding (RTM) process for the development of a full-composite aircraft hatch that does not use metal fasteners . Tornado reported successful verification of the door design using a proprietary patented geometrically-locked composite attachment that achieves a completely fastener-free structure compared to the aluminum and black aluminum composite now in use Material door, weight loss and cost up to 30%.
