Abstract
Fiber-containing composite particles and fiber-reinforced barrier matrix compositions made from them are disclosed. The composite particles include a core, a hydratable clay mineral layer, an optional protective coating, and a reinforcing fiber. The fiber may be present in any or all of several locations: adhered to the core, dispersed in the hydratable layer or in the protective coating. Upon hydration, the hydratable clay mineral layer swells and forms a matrix that cohesively holds the fibers and the core in a fiber-reinforced barrier matrix composition.
