Abstract
A number of computer simulations have been performed in order to assess the ballistic penetration resistance of a series of textile panels. The results indicate that the rate of energy absorption of the panel increases monotonically with the fibre modulus, but that very high modulus material tends to exhibit poor impact resistance due to its low breaking strain. Aramid fibre seems to exhibit the best combination of high modulus while still maintaining reasonably high breaking strain. A ‘master-curve’ description of impact response has been developed from the computer results, which may be useful in minimising the number of full computer simulations necessary in the design of impact protective devices.
