Problems solved by technology

Structures housing electrical circuits can be prone to exposure to electromagnetic conduction or electromagnetic radiation, which can impair operation without adequate protection.
Structures that are relatively tall as compared to surrounding structures or objects can be prone to lightning strikes, which can severely damage or even destroy the structures without electrical conductivity or added means to carry the electrical load.
Minor or reparable structural damage to structures can quickly progress to serious or even complete failure without prompt detection.
Shear, tensile, and compressive forces at critical locations on structures can cause failure over time without adequate structural integrity.
Crack propagation can cause serious or even complete failure, if not prevented when micro-cracks initially form.
Variations in temperature or other factors can affect the structure with inadequate thermal conductivity.
These and additional demands placed on land-based structures result in difficulty in selecting materials suitable to address each demand.

Embodiment Construction

[0018]Tailored multiscale composites have been developed utilizing CNT-infused fibers. CNTs can be grown directly onto the surface of glass and carbon fibers in a continuous, in line process utilizing a modified CVD process, such as the one described in Applicant's co-pending applications, U.S. Publication Nos. 2010 / 0279569 and 2010 / 0178825, both of which are incorporated herein by reference in their entirety. Composite structures made with CNT-infused fiber materials have shown increased mechanical properties, specifically in shear—interlaminar and in-plane. Additionally these composite structures have improved electrical and thermal conductivity, based on the CNT loading and orientation. These CNT-infused fiber materials can be used in composite structures in various orientations and locations to provide custom tailored properties, including properties not available to current fiber materials.

[0019]The CNT-infused fiber composite can employ any type of fiber substrate, including, ...

Description

[0001]This application claims priority from U.S. Provisional Patent Application Nos. 61 / 263,807, filed Nov. 23, 2009, and 61 / 286,340, filed Dec. 14, 2009, both of which are incorporated herein by reference in their entirety.STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT[0002]Not applicable.BACKGROUND AND FIELD OF THE INVENTION[0003]The present invention generally relates to carbon nanotubes (CNTs), and more specifically to CNTs incorporated in composite materials and structures.[0004]Hybrid composites have been used with varying degrees of success. The use of two or three different reinforcements within a composite has been accomplished along with the addition of aggregates and fillers used for various purposes including mechanical strengthening, cost reduction, smoke prevention, chemical resistance, and the like.[0005]Land-based structures are subject to a number of demands on operability and efficiency. Structures housing electrical circuits can be prone to exposu...
