SUMMARY:

A novel family of composite laminates with simplified stacking sequence in form of two double ply (double-double) [±ø/±ψ]n offers great potential to reduce weight and increase mechanical strength, while facilitating design optimization and simplifying manufacturing process when compared to traditional quadriaxial composite materials (Quad) with ply angles of 0o, ±45o and 90o.. In this study, low-velocity impact response of a double-double (DD) laminate and a quadriaxial laminate of equivalent in-plane 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.
