Needle‐punched felt samples differing widely in ballistic performance have been subjected to four different types of high speed mechanical tests. These tests included penetration, tensile, compression, and instrumented dart‐drop methods. The results from one of these high speed tests, the penetration test, can be consistently related to the ballistic resistance of the felts. This penetration test utilizes a compression cage equipped with a penetrant and is operated at test speeds about two decades lower than those realized ballistically. The other three tests are of only limited use in evaluating felts.
