Publication number: 20100260998Abstract: A fiber sizing formulation includes (1) a nanoparticle (NP)solution that includes a dispersion of transition metal nanoparticles (NPs) in a solvent and (2) a first fiber sizing agent. The NPs disperse throughout the first fiber sizing agent after application of the fiber sizing formulation to a fiber and removal of the solvent. The NPs serve a function selected from a secondary sizing agent, a catalyst for further nanostructure growth on the fiber, and combinations thereof. A fiber includes a sizing disposed about the fiber. The sizing includes transition metal nanoparticles dispersed throughout the sizing. A method includes applying the sizing formulation to a fiber during manufacture of the fiber, and removing the solvent from the applied formulation. A method includes adding a solution of transition metal NPs to a sizing-coated fiber and baking, whereby the sizing solution of NPs is added before baking the sizing.Type: ApplicationFiled: August 11, 2009Publication date: October 14, 2010Applicant: Lockheed Martin CorporationInventors: James A.
