NIST researchers designed a method that uses a high-intensity laser to blast microprojectiles at velocities close to the speed of sound at a target material, in this case a thin polymer film representing the puncture-resistant material to be tested. The test is called LIPIT, which stands for laser-induced projectile impact testing. Combining the test with analysis and scaling methods, scientists can discover new puncture-resistant materials.
