Methods:

Joint Testing

Joint: "a location where a component is sewn or connected to another component"

Joint Factor: "a 'loss in joint strength…relative to the basic material strength' that occurs when 'textiles are connected to each other or to metals.'”

Warp fibers: "fibers of a textile that carry the majority of the load and are in the direction of the load axis"

Fill fibers: "the fibers whose primary purpose is to organize the structure and facilitate load sharing"

3 Parachute materials:

1. Cord: Typically braided
2. Tape/Webbing:typically woven, warp and fill fibers
3. Cloth: typically woven, warp and fill fibers

A joint, by definition, is the location where two components are sewn together, being regarded as a weak point. This method of testing analyzes the strength of these joints . to obtain the joint factor, which is  The ideal situation would have the stitcehs stitches break before th ematerial the material itself, showing that the material's strength is being used at its fullest.
