Key Points

Determine whether embedding macroscopic, continuously aligned carbon nanotubes into a polymer matrix unlocks theoretical mechanical enhancements under compressive loads.
Fabricated polymer composites embedded with macroscopic, continuously aligned carbon nanotube reinforcements.
Tested mechanical performance under compressive loadings to quantify changes in longitudinal modulus and damping capability.
Evaluated baseline performance against composites fabricated with randomly distributed nanotubes of equivalent length and filler fraction.
Continuous nanotube composites exhibited an increase in longitudinal modulus of up to 3,300% (more than an order of magnitude) under compressive loads.
Damping capability in the continuous nanotube composites increased by up to 2,100%.
Randomly distributed nanotube composites with identical length and filler fraction provided three times less effective reinforcement.
