| Abstract: | A kind of long chain bismaleimide-modified cyanate ester resin and the relevant composites were prepared and characterized. The results indicate that when the resin content of the long chain maleimide-terminated thioetherimide(MIMTI) reached 37.5%(mass fraction), the T5%of the modified cyanate ester resin(MTI/T3) was 414℃. Tensile strength and flexural strength of the MTI/T3 composite were 431.2 and 331.0 MPa, 631.5 and 278.4 MPa at room temperature and 200℃, respectively. And its coefficient of thermal expansion(CTE) in X-Y axis and the moisture absorption were 18.1×10-6℃-1 and 1.4%, respectively. Compared to the common bismaleimide-modified cyanate ester resins, and the 20% and 30% MIMTI-modified cyanate ester resin MTI/T1 and MTI/T2, respectively, the obtained cyanate ester resin MTI/T3 exhibited good processing, excellent heat resistance and mechanical properties, low moisture absorption and low CTE. |
