Abstract : Apparatus for tearing fabrics in a time of 0.05 sec is described. Energy is applied by means of a falling weight which impacts a nail of known diameter inserted in a biaxially (horizontally and vertically) tensioned fabric. The tearing of a light-weight nylon fabric has been studied in factorial experiments. Analysis of variance shows that the horizontal tension and energy input are the most important factors; the vertical tension and certain interactions are also significant. Results calculated from a fitted response surface give a correlation coefficient of 0.76 with experimental results. (Author)
