J. Jang et al., FAILURE OF CERAMIC FIBRE-REINFORCED PLASTIC COMPOSITES UNDER HYPERVELOCITY IMPACT LOADING/, Journal of Materials Science, 32(1), 1997, pp. 23-33
The hypervelocity impact limit, V-50, of alumina/fibre-reinforced plas
tic (FRP) target materials was studied with different adhesive layer t
hicknesses and two kinds of FRP. A high-speed camera was used to analy
se the perforation phenomena of target materials. In addition, the dis
hing and bulging extent of FRP as a rear material were investigated us
ing a digital planimeter from a series of high-speed photographs durin
g the perforation of a projectile. In the case of the same adhesive la
yer thickness, the target material with more ductile FRP (A type) abso
rbed more impact energy than that with less ductile FRP (B type). In b
oth target materials, the highest V-50 was obtained at an adhesive lay
er thickness of 1.3 mm.
