An experimental investigation was conducted to study the effect specimen size on the buckling strains of liminates subjected to low velocity projectile impact. The fiber composite selected was T3OO52O8 graphiteepoxy system. The quasi-isotropic laminates tested had 16 and 32 plies. The results were compared with those of a 48-ply laminate tested elsewhere. Specimens of three different lengths with length to width aspect ratios of 1, 1.5 and 2 were also studied. The results show that a the specimen length does not have any significant influence on the buckling strains at failure caused by the projectile impact, b the influence of specimen thickness on the strains at failure would decrease as the velocity of the impacting projectile increases.
