Abstract
Compositions comprise (a) a curable resin sol comprising a colloidal dispersion of substantially spherical, substantially inorganic microparticles (e.g., surface-modified silica) in curable resin (e.g., epoxy resin); and (b) reinforcing fibers (e.g., carbon fibers). The compositions can be cured to provide fiber-reinforced composites which exhibit improved resin-dominated mechanical properties.
