US Patent:

53956486, Mar 7, 1995

Filed:

Nov 9, 1989

Appl. No.:

7/433946

Inventors:

H. O. Davis - Alameda CA
Marvin Pennell - San Leandro CA
Gary Patz - Walnut Creek CA

Assignee:

Kaiser Aerospace and Electronics Corporation - Foster City CA

International Classification:

B05D 300

US Classification:

427192

Abstract:

Prepregs for producing ceramic-ceramic composite articles are prepared by impregnating a ceramic substrate with a liquid ceramic precursor material. By properly controlling the viscosity of the precursor material and the conditions of application of the precursor to the substrate, a prepreg which can retain the precursor may be obtained. The prepreg is suitable for shaping into a wide variety of geometries, and the ceramic precursor may be transformed into the corresponding ceramic matrix material by curing and conversion steps.

Appl. No.:

6/174299

Inventors:

Gary L. Patz - Walnut Creek CA
Donald E. Davenport - Palo Alto CA

Assignee:

Hexcel Corporation - San Francisco CA

International Classification:

B32B 700

US Classification:

428245

Abstract:

A novel electrically and thermally conductive prepreg is provided comprising a resin impregnated fabric woven from a multiplicity of dielectric fibers at least some of which are metal-coated, e. g. aluminum-coated glass fibers. Articles made therefrom are useful for dissipation of static electricity, lightening strike protection, EMI shielding and antennae surfaces. Directional conductivity is achieved by orientation of the metal-coated fibers in the ply.
