A thermoset resin, including the reaction product of: an epoxy resin mixture including at least one cycloaliphatic epoxy resins; a cycloaliphatic anhydride hardener; and a catalyst; wherein the reaction product has a glass transition temperature greater than or equal to 210&#xb0; C. Also disclosed is a process for forming a thermoset resin, including: admixing two or more epoxy resins and a cycloaliphatic anhydride hardener to form a curable composition, wherein the epoxy resins include at least one cycloaliphatic epoxy resin; thermally curing the curable composition at a temperature of at least 150&#xb0; C. to result in a thermoset resin having a glass transition temperature of at least 210&#xb0; C. Such curable compositions may include: 35 to 65 weight percent of an epoxy resin mixture having at least one cycloaliphatic epoxy resins; 35 to 65 weight percent of a cycloaliphatic anhydride hardener; and from greater than 0 to 10 weight percent of a catalyst.
