摘要:
Flame-resistant composite materials containing carbon nanotubes are described herein. The flame-resistant composite materials contain an outer layer and at least one inner layer, containing a first polymer matrix and a second polymer matrix, respectively. The outer layer has an exterior surface and a first carbon nanotube-infused fiber material that contains a first fiber material and a first plurality of carbon nanotubes greater than about 50 μηι in length. In some embodiments, the at least one inner layer also contains a second fiber material and/or a second carbon nanotube-infused fiber material containing a second fiber material and a second plurality of carbon nanotubes. When present, the second plurality of carbon nanotubes are generally shorter in length than the first plurality of carbon nanotubes. Alignment of the carbon nanotubes in the outer layer can transfer heat away from the composite material's inner layer(s). Flame-resistant articles containing carbon nanotube- infused fiber materials are also described.
摘要:
A wire includes a plurality of carbon nanotube infused fibers in which the infused carbon nanotubes are aligned parallel to the fiber axes. An electromagnetic shield for a wire includes a plurality of carbon nanotube infused fibers, in which the infused carbon nanotubes are aligned radially about the fiber axes. The plurality of carbon nanotube infused fibers are arranged circumferentially about the wire with the fiber axes parallel to the wire. A self-shielded wire includes 1) a wire that includes a plurality of carbon nanotube infused fibers in which the infused carbon nanotubes are aligned parallel to the fiber axes; and 2) an electromagnetic shield that includes a plurality of carbon nanotube infused fibers in which the carbon nanotubes are aligned radially about the fiber axes. The axes of the carbon nanotube infused fibers of the wire and the carbon nanotube infused fibers of the electromagnetic shield share are parallel.
摘要:
A composite composition includes a plurality of carbon nanotube (CNT)-infused fibers dispersed in a matrix material. The amount of carbon nanotubes in the composition is in a range between about 0.1% percent by weight to about 60 percent by weight of the composite.
摘要:
A composite structure includes a matrix material and a carbon nanotube (CNT)-infused fiber material that includes a plurality of carbon nanotubes (CNTs) infused to a fiber material. The CNT-infused fiber material is disposed throughout a portion of the matrix material. The composite structure is adapted for application of a current through the CNT-infused fiber material to provide heating of the composite structure. A heating element includes a CNT-infused fiber material includes a plurality of CNTs infused to a fiber material. The CNT-infused fiber material is of sufficient proportions to provide heating to a structure in need thereof.
