In this paper, the boron-modified binary primary amines benzaoxazine and the binary primary amines benzaoxazine was synthesized respectively. The resin was characterized by Fourier Transform Infrared Spectroscopy spectrum respectively. The laminates, which were pressed by two kinds of resin respectively, were irradiated by γ-rays and inspected the affection of radiation resistance after introducing of boron atom by comparing the performance of laminates after radiation. The performance of mechanics and electricity was investigated before and after radiation with two kinds of laminates. The result indicates that the radiation resistance of laminate was improved by introducing boron atom.
