Cutting prepregs, cutting and processing polymer plastics in the manufacture of airсraft panels

The article presents an alternative to the solution of the problem of reduction of manual operations in manufacture. It may be achieved if cutting out prepregs and processing polymeric materials (PMP) be changed for sharp ultrasonic cutting when manufacturing components from polymeric composite materials (PCM). Described are the lines of investigations on new techniques of cutting out prepreg and processings polymeric material of the Nomex type with the use of the energy of ultrasonic waves. The obtained solutions may be applied when manufacturing stretch-forming thin-walled panels from PKM in the aerospace industry as well as in shipbuilding.
