Title: Collector surface for a microwave tube comprising a carbon-bonded carbon-fiber composite

Abstract

In a microwave tube, an improved collector surface coating comprises a porous carbon composite material, preferably a carbon-bonded carbon fiber composite having a bulk density less than about 2 g/cc. Installation of the coating is readily adaptable as part of the tube manufacturing process.

Radio-frequency and microwave load comprising a carbon-bonded carbon fiber composite

Patent Lauf, Robert J [Oak Ridge, TN]; McMillan, April D [Knoxville, TN]; Johnson, Arvid C [Lake in the Hills, IL]; ...

A billet of low-density carbon-bonded carbon fiber (CBCF) composite is machined into a desired attenuator or load element shape (usually tapering). The CBCF composite is used as a free-standing load element or, preferably, brazed to the copper, brass or aluminum components of coaxial transmission lines or microwave waveguides. A novel braze method was developed for the brazing step. The resulting attenuator and/or load devices are robust, relatively inexpensive, more easily fabricated, and have improved performance over conventional graded-coating loads.

Method for fabricating light weight carbon-bonded carbon fiber composites

Patent Wrenn, Jr., George E. (Clinton, TN); Abbatiello, Leonard A [Oak Ridge, TN]; Lewis, Jr., John (Oak Ridge, TN)

Ultralight carbon-bonded carbon fiber composites of densities in the range of about 0.04 to 0.10 grams per cubic centimeter are fabricated by forming an aqueous slurry of carbonaceous fibers which include carbonized fibers and 0-50 weight percent fugitive fibers and a particulate thermosetting resin precursor. The slurry is brought into contact with a perforated mandrel and the water is drained from the slurry through the perforations at a controlled flow rate of about 0.03 to 0.30 liters per minutes per square inch of mandrel surface. The deposited billet of fibers and resin precursor is heated to cure the resin precursormore » « less

Microwave and plasma-assisted modification of composite fiber surface topography

Patent Paulauskas, Felix L [Knoxville, TN]; White, Terry L [Knoxville, TN]; Bigelow, Timothy S [Knoxville, TN]

The present invention introduces a novel method for producing an undulated surface on composite fibers using plasma technology and microwave radiation. The undulated surface improves the mechanical interlocking of the fibers to composite resins and enhances the mechanical strength and interfacial sheer strength of the composites in which they are introduced.
