Abstract: |
This article reviews the modification studies of six types of curing agents such as dicyandiamide, imidazole and acid anhydride in order to meet the needs of medium-low temperature curing and long pot life, and analyzes and compares their performance and application prospects. The curing process characteristics and application status of medium-low temperature curing epoxy prepregs and composites are also introduced. Finally, the future development trend of medium-low temperature curing technology is analyzed. |
