STUDY OF MECHANICAL PROPERTIES AND HEAT RESISTANCE OF EPOXY RESIN MODIFIED BISMALEIMIDE COMPOSITES

Abstract

Abstract: In order to study the properties of epoxy (EP) resin modified bismaleimide (BMI) resins, four kinds of epoxy resin: AFG-90, TDE-85, E-14 and D-17 modified BMI resins were prepared. BMI and EP modified BMI resins were processed into prepregs with carbon fiber (CF) grid cloth. The prepregs were made into composites through laminated molding. The infrared absorption spectrum of cured resin system was tested. The curing curves of unmodified and four EP modified resins and the glass transition temperature (T_g) was tested by DSC. The bending strength and impact toughness of the samples were test by a universal mechanical test machine. And the damaged morphology were observed and recorded by SEM. The results indicate that the EP and BMI are cured on different temperature with good compatibility. It was found that the enhancement of TDE-85 group was best, and the D-17 has the best toughening effect which fits the strengthing and toughing rules. The T_gs of AFG-90,TDE-85,D-17 were higher than 200℃, which suggests that EP modified BMIs did not sacrifice their heat resistance.
