Ballistic behaviour of hybride carbon/basalt fiber reinforced epoxy-hBN composite

Ballistic behaviours of hybrid composite armors were investigated through experiments. The effects of hexagonal boron nitride (h-BN) nanopowders and number of layers on ballistic performance were examined. Four types of armors were manufactured by hand lay-up and vacuum bagging technique: 60 layers of fabric (30 layers carbon and 30 layers basalt fabrics) with 0% h-BN (1-A) and 1% h-BN (1-B), also 100 layers of fabric (50 layers carbon and 50 layers basalt fabrics) with 0% h-BN (2-A) and 1% h-BN (2-B) with epoxy resin. Ballistic impact tests were performed on the armors using a 9 mm full metal jacket projectile. The densities of the ballistic plates are 1.53, 1.56, 1.61 and 1.65 respectively. After three shots to each plate, the average hole depths were 5.55 mm on the 1-A coded plate, 4.34 mm on the 1-B armor, 4.68 mm on the 2-A plate, and 4.69 mm on the 2-B armor. All of the armors were able to confront for the velocities between [Formula: see text] m/s successfully. However, the h-BN showed a significant influence on the overall ballistic performance of composite armors. It has been found that the penetration depth decreases with the addition of h-BN. Also SEM-EDS mapping and XRD analysis were used to characterize the hybrid composites.
