Abstract
Carbon nanotubes (CNTs) are so long that they cannot be penetrated inbetween carbon fibers during a prepreg preparation process, and are shortened in order for them not to be filtered out by the carbon fibers. This results in a huge improvement of the mechanical properties (flexural strength and flexural modulus) compared with neat epoxy.
