Abstract
A curable benzoxazine resin composition for a fiber-reinforced composite material is provided which contains at least a component [A], a component [B], and a component [C]. The component [A] includes at least one multifunctional benzoxazine resin having a non-hydrocarbon linkage such as carbonyl, oxygen, sulfur, sulfone or sulfoxide between aromatic moieties. The component [B] includes at least one multifunctional benzoxazine resin having a direct bond or a hydrocarbon linkage between aromatic moieties. The component [C] includes at least one cycloaliphatic epoxy resin containing at least two epoxy groups which are part of cycloaliphatic rings. The curable benzoxazine resin composition is useful in the molding of fiber-reinforced composite materials. More particularly, the curable benzoxazine resin composition makes possible a fiber-reinforced composite material where the cured material obtained by heating has superior performance in extreme use environments, such as high temperature and high compressive load.
