N2 - Epoxy resin (EP) and polyurethane (PU) matrix had an outstanding performance. They were widely used in the aerospace field and became the most popular polymer matrix. In this article, precursor of EP-PU was prepared by epoxy as a matrix, polyurethane as toughening agent, MTHPA as the curing agent. The mass ratio of the PU was 30wt%in this system. SiO2-Al2O3/EP-PU nano-composite material was synthesized, PU-EP as organic precursor, nano-SiO2 and nano-Al2O3 as filler. FT-IR and SEM were used as microstructure analysis of SiO2-Al2O3/EP-PU composite, and the results indicated that new adsorption peaks appeared in FT-IR spectra, inorganic components could uniformly disperse in the polymer matrix in SEM photos. When inorganic component content was 10wt% and the mass ratio of SiO2 and Al2O3 was 4.5:5.5, mechanical properties of SiO 2-Al2O3/EP-PU suggested that shearing strength was 28.5MPa, breakdown field was 15kV/mm. The properties could meet the requirement of insulating material.
