Epoxy/glass fiber composite materials have the characteristics of light weight, high strength, large modulus, good corrosion resistance, excellent electrical properties, wide range of raw materials, good processability, simple processing and molding, high production efficiency, and strong material designability and special functionalities such as shielding electromagnetic waves and noise reduction. They have now become irreplaceable important materials in the national economy, national defense construction, and technological development, It is currently one of the most widely used composite materials.

Medium temperature cured epoxy matrix resin has been widely used in glass fiber reinforced composite prepregs due to its advantages of low curing temperature, short molding cycle, and meeting storage requirements. However, due to the brittleness of the cured products of the non toughened epoxy matrix resin, the composite material made from it is damaged due to the premature failure of the epoxy matrix resin. Therefore, the toughening modification of epoxy matrix resin is particularly important.

At present, epoxy matrix resins can be toughened through rubber elastomers, thermoplastic plastics, etc. The latest data also indicates that using hyperbranched polymers to toughen epoxy resins has achieved good results. Whether traditional liquid rubber or thermoplastic, their blends with epoxy resin undergo phase separation during curing. Under normal circumstances, toughening agents precipitate from the blends, and phase separation and curing reactions are competitive processes. Therefore, the aggregated structure and performance of the cured product depend on the curing specifications, the properties of the added toughening agent, and its dosage. Only by strictly controlling these factors can the best toughening effect be achieved.
