Abstract:

Described herein are methods of improving the durability of concrete by the infusion of the concrete with a low-viscosity oligomeric solution, and subsequent curing of the oligomeric solution to form a high toughness polymer. Also described herein are compositions containing concrete and high toughness polymers, and formed articles made from concrete and high toughness polymers. The methods and compositions are useful for improving the durability of concrete roads and structures, as well as the durability of repairs to concrete roads.

Apr 2, 1984

Appl. No.:

6/595884

Inventors:

Wei H. Kao - Rancho Palos Verdes CA

Assignee:

The Aerospace Corporation - El Segundo CA

International Classification:

B22C 100

US Classification:

164520

Abstract:

A metal matrix composite is produced by closely aligning together a sheet of hydrided or hydrogenated alloy with a filament preform at a relatively low temperature. The resulting metal matrix will have a minimum of excessive chemical reactions at the alloy-filament interface thereby allowing the composite to achieve theoretical mechanical property values.

Filed:

Aug 23, 1988

Appl. No.:

7/235348

Inventors:

Wei H. Kao - Rancho Palos Verdes CA
Howard A. Katzman - Los Angeles CA
Eric M. Slater - Redondo CA

Assignee:

The Aerospace Corporation - El Segundo CA

International Classification:

B05D 700

US Classification:

427214

Abstract:

Filaments are coated with MgO to create an effective diffusion barrier between the filament and the matrix in a metal matrix composite, thereby improving the strength and the service life of the composite.
