Abstract

Compositions and methods for forming epoxy resin are provided, and compositions and methods for forming epoxy resin composites are provided. In one embodiment, a composite comprises an epoxy resin composition comprising an epoxy resin component comprising a glycidyl ether of an aryl substituted phenolic compound, a curing agent component, and a substrate. In one embodiment, a composite comprises an epoxy resin composition comprising an epoxy resin component and a curing agent component comprising an aryl substituted phenolic compound, and a substrate.

First claim

What is claimed is:

1. A composite, comprising:
an epoxy resin composition comprising:
an epoxy resin component comprising a glycidyl ether of an aryl substituted phenolic compound with the aryl substituent free of an epoxy containing substituent; and
a curing agent component; and

a substrate, wherein the aryl substituted phenolic compound is selected from the group consisting of an aryl-substituted bisphenol with the aryl substituent free of active hydrogen groups, an arylhydroquinone with the aryl group free of active hydrogen groups, an arylresorcinol with the aryl group free of active hydrogen groups, and combinations thereof.

2. The composite of claim 1 , wherein the aryl substituted phenolic compound is selected from the group of 2,2′-diphenylbisphenol A, 4-phenylresorcinol, 5-phenylresorcinol, 2-phenylhydroquinone, 2,5-diphenylhydroquinone, and combinations thereof.

3. The composite of claim 1 , wherein the epoxy resin composition comprises:
from about 10 wt. % to about 95 wt. % of the epoxy resin component; and
from about 90 wt. % to about 5 wt. % of the curing agent component, wherein the total component wt. % comprises 100 wt. %.

4. The composite of claim 1 , wherein the curing agent component comprises an amine-containing component.

5. The composite of claim 1 , wherein the curing agent component comprises:
an amine-containing component; and
an aryl substituted phenolic compound selected from the group of an aryl-substituted bisphenol with the aryl substituent free of active hydrogen groups, an arylhydroquinone with the aryl group free of active hydrogen groups, an arylresorcinol with the aryl group free of active hydrogen groups, novolacs having phenolic rings substituted with aryl groups free of active hydrogen groups, and combinations thereof.

6. The composite of claim 1 , wherein the substrate comprises a reinforcing fiber substrate.

7. The composite of claim 1 , wherein the epoxy resin component comprises from about 10 wt. % to 99.5 wt. % of the composite.

8. The composite of claim 1 , wherein the epoxy resin composition further comprises a second epoxy resin component free of a glycidyl ether of an aryl substituted phenolic compound with the aryl substituent free of an epoxy containing substituent.

9. The composite of claim 8 , wherein the second epoxy resin component comprises a glycidyl amine epoxy resin or mixtures of glycidyl amine epoxy resins.
