摘　　要：该文对AN/PU复合材料基体的共混改性进行了理论和实验研究。通过表观交联度等参数表征HTPB-ITPU共混体系的改性效果,并用SEM、DSC和IR等现代分析手段对多相体系的界面相互作用进行了探讨。结果表明,基体的共混改性是提高AN/PU复合材料力学性能的重要途径。This paper has studied theoretically and experimentallythe blend modification of AN/PU composite material matrix. Themodified effects of HTPB--ITPU blends are characterized by apparentcrosslinking density and other factors, and the interfacial interactionof the polyphase system is discussed with the help of SEM, DSC andIR modern analysis methods. The results have shown that the blendmodification of matrix is an important method to enhance mechanicalproperty of AN/PU composite material.
