Concerning the Application Possibility of Ultrasonic Welding of Textile Materials on the Basis of Synthetic Fibres in the Manufacturing Processes of Parachute Systems

Abstract:

The application possibility of ultrasonic () welding in the technological process of the canopies of braking parachute systems manufacturing for the unmanned aerial vehicles was considered. The subjects of research were parachute fabrics (100 % capron), manufactured by with different surface weight, weave and type of finish. Welding modes were chosen. The obtained welded seams had no defects and met the requirements of technical standard documentation, with the increase of the distance between the welding spots, the welding strength of the welded seam was decreased by 10–40 %. The strength of the seams at the “in shear” test is on the average 2-3 times larger than at the gripping method test. The draft of the nozzle-roll for executing the spotted welded seams was proposed. The calculations suggested that the application of the welded seams instead of sewn seams would allow the reduction of the costs for sewing threads during the manufacturing of the canopy to 50 % and the significant reduction of the labour requirement.
