Characterization of Fraglight Non-Woven Felt and Simulation of FSP's Impact in It
Abstract
The objective of this project is to gain insight in the behavior of the non-woven felt commercially know as Dyneema Fraglight. The following activities were performed during the period covered by this report: 1) Tests at different temperatures and orientations. 2) Search of characteristic length of fiber and fabric. 3) High strain rate specimen designed and difficulties in Hopkinson bar testing. 4) Calibration and set-up of the image system that will record the history of the impact of FSPs into the Dyneema Fraglight. The main conclusions are I) The characteristic length of the fiber is 4-5 cm. 2) Heating the fabric at 100 C weakens it by 40% .3) Longitudinal and 45 degrees specimen are much weaker than transverse specimens. 4) Hopkinson bar tests will be difficult since specimens strain too much before failing. 5) Preliminary shooting tests with high speed photography indicate it is possible to obtain longitudinal and transverse wave speed in the fabric.
