SUMMARY:

A novel family of composite laminates with simplified stacking sequence in form of two double ply (double-double) [±Ω/±ψ]n offers great potential to reduce weight and increase mechanical strength, while facilitating design optimization and simplifying manufacturing process. In this study, low-velocity impact response of a double-double laminate and a quadriaxial laminate of equivalent stiffness and same thickness were compared. Carbon/epoxy laminates were produced with stacking sequences of [±0/±50]10 and [03/90/±45/02/±45]2S, corresponding to double-double and quadriaxial, respectively. Low-velocity impact tests were conducted at energy of 74 J and damage areas were examined using x-ray computed tomography. Measured compressive strength and compression after impact (CAI) strength were equivalent for double-double and quadriaxial laminates. However, differences in impact damage morphology were observed and are discussed.
