Abstract
Provided are a resin composition, a resin cured product, and a fiber reinforced resin capable of shortening a stress relaxation time. In order to solve this problem, the resin composition contains an epoxy compound having two or more epoxy groups in a molecule, an acid anhydride, and a complex in which an organic ligand is coordinated to manganese (III). The resin cured product contains a resin having an ester group and a hydroxy group, and a complex in which an organic ligand is coordinated to manganese (III). A fiber reinforced resin 101 contains a resin 1 having an ester group and a hydroxy group, fibers 2 impregnated with at least the resin, and a complex 3 in which an organic ligand is coordinated to manganese (III).
Claims10
A resin composition comprising:
- an epoxy compound having two or more epoxy groups in a molecule;
- an acid anhydride including at least one of phthalic anhydride, tetrahydrophthalic anhydride, hexahydrophthalic anhydride, and derivatives thereof;
- and
- a complex in which an organic ligand is coordinated to manganese (III), the complex contains at least one of manganese (III) acetylacetonate, manganese (III) acetate, and manganese (III) naphthenate,
- wherein a content of the complex is 15 mol % or more and 30 mol % or less relative to the epoxy groups, and
- wherein a content of the acid anhydride is 40 mol % or more and 70 mol % or less relative to the epoxy groups.
A resin cured product comprising:
- a resin having an ester group and a hydroxy group obtained by a reaction between an epoxy compound having two or more epoxy groups in a molecule and an acid anhydride including at least one of phthalic anhydride, tetrahydrophthalic anhydride, hexahydrophthalic anhydride, and derivatives thereof, wherein a content of the acid anhydride is 40 mol % or more and 70 mol % or less relative to the epoxy groups;
- and
- a complex in which an organic ligand is coordinated to manganese (III), wherein the complex contains at least one of manganese (III) acetylacetonate, manganese (III) acetate, and manganese (III) naphthenate,
- wherein a content of the complex is 15 mol % or more and 30 mol % or less relative to the hydroxy group.
A fiber reinforced resin comprising:
- a resin having an ester group and a hydroxy group obtained by a reaction between an epoxy compound having two or more epoxy groups in a molecule and an acid anhydride including at least one of phthalic anhydride, tetrahydrophthalic anhydride, hexahydrophthalic anhydride, and derivatives thereof, wherein a content of the acid anhydride is 40 mol % or more and 70 mol % or less relative to the epoxy groups;
- a fiber impregnated with at least the resin;
- and
- a complex in which an organic ligand is coordinated to manganese (III), wherein the complex contains at least one of manganese (III) acetylacetonate, manganese (III) acetate, and manganese (III) naphthenate,
- wherein a content of the complex is 15 mol % or more and 30 mol % or less relative to the hydroxy group.
