In order to improve the stiffness of epoxy matrix, polyfimctional epoxy resin was modified with amide acid oligomer, and the high modulus epoxy resin matrix was prepared.The properties of modified resin matrix have been characterized by gel permeation chromatography, Fourier infrared spectrum, mass spectrometry, differential scanning calorimeter instrument, viscosity and solubility test.
