Some Observations on the Behaviour of Superimposed and Lap Sewn Joints

Abstract

Two polyester sewing threads with different breaking strengths were used in the construction of sewn joints in four types of webbing for parachutes. The joints were made having either a 3-point double W stitching pattern of various lengths or a number of rows of transverse stitching. The breaking strength of the stitched joints attained a limiting value. Various methods of seam strength prediction have been investigated.
