Abstract
Low viscosity ternary mixtures of benzoxazine, epoxy and phenolic resins have been developed. The blends render homogeneous and void free cured specimen with a wide range of properties. Melt viscosity values as low as 0.3 Pa.s at 100° C. can be achieved. The phenolic resin acts as a cure accelerator to the system, besides its typical function as a hardener of epoxy resin. Glass transition temperatures Tg as high as 170° C. can also be obtained.
