人们对复合材料的加工进行了许多研究。过去除采用钻头、郁金香形铣刀等“传统”加工方法外,还利用水喷射法进行复合材料的切割。而今天,人们发明了超声波。美国一公司(Energy and Minerale Research Co d′ Exton en Pennsy Lvanie)研制出一种微型工具——超声波刀,这种刀可切割硬度很高或易碎的材料,不管是干纤维还是浸渍过的纤维均可,例如armide纤维,玻璃,石墨。这套微型工具还可对蜂窝状铝材料和Nomex材料进行钻孔和型面加工。值得注意的是,大部份试验是在DuPont de Nemous公司生产的纤维和复合材料上进行的(主要是Kevlar和Nomex材料)。超声波刀不仪适于切割和型面加工青铜夹层板,同样适于切割氯丁橡胶,未硫化橡胶,Kevlar增强橡胶,铝板,惰性固体推进剂, Many studies have been conducted on the processing of composites. In addition to the past, using the drill, tulip-shaped cutter and other “traditional” processing methods, but also the use of water jet method for cutting composite materials. Today, people invented the ultrasound. A miniature tool, the Ultrasonic Knife, developed by Energy and Minerale Research Co d ’Exton and Pennsy Lvanie, can cut hard or fragile materials, either dry or impregnated Can be, for example armide fiber, glass, graphite. This miniature tool also drills and shapes honeycomb aluminum and Nomex materials. It is noteworthy that most of the tests were carried out on DuPont de Nemous fibers and composites (mainly Kevlar and Nomex materials). Ultrasonic knives are not suitable for cutting and surface processing of bronze sandwich panels, also suitable for cutting neoprene, unvulcanized rubber, Kevlar reinforced rubber, aluminum plates, inert solid propellants,
