Claim Text:
1. A composite for use in electromagnetic interference (EMI) shielding applications comprising: a carbon nanotube (CNT)-infused fiber material disposed in at least a portion of a matrix material, said composite being capable of absorbing electromagnetic (EM) radiation, reflecting EM radiation, or combinations thereof in a frequency range from between about 0.01 MHz to about 18 GHz, wherein the EM shielding capacity of the composite, measured as electromagnetic interference (EMI) shielding effectiveness (SE), is in a range from between about 40 decibels (dB) to about 130 dB, wherein CNTs of the CNT-infused fiber material display a CNT morphology resulting from synthesis of the CNTs directly on the fiber material, the CNT morphology comprising entangled, branched and shared-wall CNTs, and the CNTs extending outwardly from a fiber material comprising the CNT-infused fiber material; wherein the CNT-infused fiber material has a controlled orientation within the composite.
