Development of a 46 ft ribbon parachute required design of new and improved narrow fabrics. These included a lightweight, low porosity, 550 lb reinforced selvage nylon ribbon; a low porosity 1000 lb nylon ribbon; and a 2400 lb Kevlar webbing. Tensile elongation, lateral contraction, and other mechanical properties were measured as a function of load at room and elevated temperature to evaluate the fabrics and determine possible sources of parachute porosity variation. The property changes were too small to cause the parachute porosity to change significantly during deployment. Broken fill yarns observed in some Kevlar suspension line webbing after parachute deployment led to high rate loading tests to investigate conditions that might cause fill breakage. It was shown that fill damage did not reduce the strength of Kevlar suspension lines.
