The present technology provides an epoxy resin composition for a fiber-reinforced composite material, a method for producing an epoxy resin composition for a fiber-reinforced composite material, a prepreg, and a honeycomb panel. The epoxy resin composition for a fiber-reinforced composite material of the present technology contains: a reaction product obtained by reacting 100 parts by mass of a phosphorus-containing epoxy resin containing a phosphorus atom in the backbone thereof, and not less than 5 parts by mass and not greater than 20 parts by mass of an amino-terminated butadiene-acrylonitrile rubber; an epoxy resin other than the phosphorus-containing epoxy resin; a curing agent; and a curing accelerator.

The present teachings provide a method and composition related to two component epoxy phosphate ester based foam materials. The present teachings provide a method comprising: providing a two component system, the two component system including an A side and a B side, the A side including epoxy and the B side including phosphate ester and phosphoric acid; mixing the A side and the B side to form a resulting reaction product; wherein the resulting reaction product of the A side and the B side cures at a temperature of less than 50° C. The present teachings provide a composition comprising: a) a first component including epoxy; b) a second component including phosphate ester and phosphoric acid; and wherein a resulting reaction product of the first component and second component cures at a temperature of less than 50° C.

The polyurethane flame retardant is prepared by compounding poly(diphosphophosphazene) (PDPP) and derivatives thereof, poly(diphosphate phosphazene) (MPDPP) (where M=Mg.sup.2+, Ca.sup.2+, transition metal ions, rare earth ions and the like) and poly(diphosphonic phosphazene). Since a phosphate group in the PDPP and an unreacted phosphate group in the MPDPP in the compound and an unreacted hydroxyl in the phosphate group may react with isocyanate, the flame retardant is a reactive flame retardant. Due to the reaction between the flame retardant and the isocyanate, the flame retardant is uniformly distributed in polyurethane and has a better flame-retardant effect. The flame retardant contains multiple flame-retardant components, namely polyphosphazene group, phosphate ester and phosphate salt. Due to the synergistic effect, the flame retardant has good flame-retardant properties, and can be used for various polyurethane materials.
