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.

Application of high toughness, low viscosity nano-molecular resin for reinforcing pothole patching materials in asphalt and concrete base pavement

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.

Metal matrix composite made with reduced interface reactions

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.
