Abstract

To investigate effects of projectile nose shape on anti-impact performance of carbon fiber reinforced plates (CFRPs)，a one-stage gas gun was used to launch ogival-nosed projectiles, hemispherical-nosed ones and blunt-nosed ones on the target of a 2mm thick CFRP in impact tests. The test data were processed using the formula fitting method to reveal effects of projectile nose shape on the target plate’s ballistic limit and energy absorption, and analyze impact damage morphology and mechanism features of the target plate. The results showed that blunt-nosed projectiles’ ballistic limit is the highest, hemispherical-nosed ones’ is the second, and oval-nosed ones’ is the lowest; when projectiles impacting the target at low velocity, effects of projectile nose shape on target plate energy absorption rate are more significant; when blunt-nosed projectiles impacting target, target plate facing surface is subjected to uniformly distributed annular shear force, and fibers are cut at the same time, plate’s matrix has large area shear failure; when hemispherical-nosed projectiles impacting target, target plate facing surface is subjected to non-uniform distributed shear force and squeezing action, fibers have shear fracture and tensile fracture, and matrix has shear failure and attrition crushing; when ogival-nosed projectiles impacting target, fibers have single tensile fracture while matrix has attrition crushing; effects of projectile nose shape on target damage mainly focus on facing surface and middle fiber layers.
