1. Consistency and controllability: The impregnation of resin and fibers during the manufacturing process of prepregs takes place in the factory, allowing for a high degree of consistency and controllability. Compared to manual impregnation on site, prepregs ensure uniform and consistent resin impregnation.

2. High Strength and Stiffness: The fibers are impregnated with resin in the prepreg, allowing the fibers to fully bond with the resin to form a homogeneous composite. This provides higher strength and stiffness, resulting in prepreg products with excellent structural support and reinforcement.

3. Good corrosion resistance: The resins used in prepregs usually have good corrosion resistance and are able to resist acid, alkali and other chemicals, making them suitable for use in a variety of harsh environmental conditions.

4. Easy molding: Since the resin is already impregnated in the prepreg, simple processes such as heating and pressing or vacuum molding are all that is needed during the molding process. Compared to on-site manual impregnation, prepregs greatly simplify the molding process and increase productivity.

5. Lightweight: Compared with traditional metal materials, prepreg composites have a lower density, so they can realize lightweight design, reduce the weight of the overall structure, and improve energy efficiency.

6. Good mechanical properties: products made from prepregs have excellent tensile strength, abrasion resistance and impact resistance, making them suitable for applications requiring high strength and durability, such as aerospace and automotive.

7. Overall, fiberglass fabric prepregs offer the advantages of consistency and controllability, high strength and stiffness, corrosion resistance, ease of molding, light weight and good mechanical properties. This has led to the widespread use of prepregs in aerospace, automotive, construction and other fields, and is gradually replacing the traditional manual impregnation process.
