When selecting a suitable protective material, it is first necessary to ensure that the characteristics of the homogeneous materials have been tested and assessed in accordance with their intended use. Here, factors such as strength and deformability under impact-like loading rates play an important role, permitting a basic assessment of the potential protective materials.
Toughness is also a crucial factor when selecting the materials that will be used for protective purposes. For this reason, we collaborated with partners we developed a tester that can be used to quickly assess toughness. This test is a modified drop-weight tear test.
