Abstract:
A nanocomposite is provided including spherical pyrogenic silica nanoparticles dispersed in a curable resin or a curing agent. The nanocomposite contains less than 2% by weight solvent and less than 0.5% by weight dispersant based on the nanoparticle weight. A composite is also provided including from about 4 to 70 weight percent of spherical pyrogenic silica nanoparticles dispersed in a cured resin, and a filler embedded in the cured resin. Optionally, the composite further contains a curing agent. Further, a method of preparing a nanoparticle-containing curable resin system is provided including mixing from 10 to 70 weight percent of aggregated spherical pyrogenic silica nanoparticles with a curable resin to form a mixture. The mixture contains less than 2% by weight solvent and less than 0.5% by weight dispersant based on the nanoparticle weight. The method also includes milling the mixture in an immersion mill containing milling media to form a milled resin system including silica nanoparticles dispersed in the curable resin.

Claim (Index 4):
The composite of  claim 1 , further comprising at least one processing aid selected from the group consisting of curing agents, cure accelerators, defoamers, air release agents, crosslinking agents, dyes, flame retardants, pigments, impact modifiers, and flow control agents.
