Abstract

High volume fraction aligned carbon nanotube (CNT) polymer nanocomposites (A-PNCs) are fabricated by biaxial mechanical densification of the CNTs, followed by polymer infiltration via capillarity-assisted wetting using an aerospace-grade epoxy. These A-PNCs are then tested in tension in order to determine the full constitutive relation of the material. Prior to this work, only bulk compression or nanomechanical tests have been attempted due to the small size of the samples. Elastic stiffness derived from optical strain mapping is in agreement both with prior experimental nanoindentation measurements and finite element calculations that include the effects of waviness of the reinforcing CNT 'fibers'. Results from longitudinal and transverse testing are shown for 0, 4, and 6 % volume fraction CNT reinforcement, and imaging via scanning electron microscopy and micro-computed tomography is used to establish morphology. Future work includes tests to establish the shear modulus and complete the full constitutive relation as a function of CNT volume fraction.
