Abstract
Stable, fluid, moldable and curable compositions are described from which may be fabricated composite materials, of improved mechanical properties, comprising an organic polymer matrix and a particulate inorganic reinforcing phase dispersed in and bonded to the matrix. The fluid compositions comprise (A) a polymerizable organic liquid having a viscosity not greater than 50 poise at the molding temperature, (B) inorganic filler particles of defined size constituting at least 20% by volume, and optionally up to 90% by volume, of the total composition, and (C) a defined polymeric dispersant whereby the filler particles are stably dispersed in the polymerizable liquid. The generally low viscosity of the curable compositions enables them to be cast by simple techniques and polymerization of the component (A) yields the above-described composite materials.
