In the present paper. the high velocity impact of 9 mm soft lead projectile on 10 mm and 30 mm thick E-glass/epoxy composites was studied using a 450 kV Flash X-ray radiography (FXR) system. The basic parameters of FXR imaging. such as effect of ratio of target to film (TF) and source to target (ST) distances and X-ray penetration thickness of the composite material were optimized bas... https://midwaysportes.shop/product-category/lacrosse-sticks/
