| Popis: |
The fragmentation of ceramic tiles under ballistic impact has been studied. Fragments and aerosol (respirable) particles were collected and analyzed to determine the total surface area generated by fracturing (macro-cracking and comminution) of armor grade ceramics. The larger fragments were collected and the mass distribution was obtained from sieving. The aerosol particles were collected using a particle impactor device that counts the number of particles of specific ranges in size. From the total surface area of all particles was concluded that fracture energy is small compared to impact energy. The average grain size of the ceramic tiles did not lead to a specific peak in mass or concentration for that particle size. In fact, a large concentration of much finer particles has been obtained. The size of the aerosol dust ranged between 10 micron and 10 nanometers, indicating a lot of particle fragmentation (comminution) to have taken place. |
