An epoxy resin composition for fiber-reinforced composite materials, which contains at least the following constituent elements [a]-[f], and which is characterized by containing 5-25 parts by mass of constituent element [c] and 2-15 parts by mass of constituent element [e] per 100 parts by mass of the total epoxy resin blended therein.

Dual function proppants
Proppants for use in fractured or gravel packed/frac packed oil and gas wells are provided with a contaminant removal component to remove one or more of the contaminants found in subterranean water/hydrocarbon from a production well. The water/hydrocarbon cleaning proppant solids may be used as discrete particles in a proppant formulation, as a coating on proppant solids in pores of a porous proppant solid or as part of the proppant's internal structure.
