The hot bending forming process of PC+PMMA composite sheets offers significant advantages, which are mainly reflected in the following aspects:

1. **Excellent Mechanical Properties**: Polycarbonate (PC) possesses high impact resistance and toughness, while polymethyl methacrylate (PMMA) exhibits high hardness and wear resistance. When combined, the composite sheet maintains high strength and rigidity during the hot bending process. The formed products are less prone to deformation or cracking, making them suitable for applications requiring high mechanical performance.

2. **Superior Optical Properties**: PMMA has excellent light transmittance and gloss, while PC offers good UV resistance. After hot bending, the composite sheet features a smooth surface, high transparency, and effective resistance to UV aging. This makes it ideal for products requiring high transparency and weather resistance, such as automotive lamp covers and architectural skylights.

3. **Outstanding Processability**: PC+PMMA composite sheets exhibit excellent plasticity during hot bending, allowing processing at relatively low temperatures, which reduces energy consumption and processing time. Additionally, the sheets offer high forming precision, enabling the realization of complex curved designs to meet diverse product requirements.

4. **Environmental and Cost Benefits**: PC+PMMA composite sheets are recyclable, aligning with environmental standards. Moreover, the hot bending process is simple and efficient, reducing production costs and enhancing economic benefits.

In summary, the hot bending forming process of PC+PMMA composite sheets demonstrates significant advantages in mechanical properties, optical properties, processability, and environmental and cost efficiency. It is widely used in industries such as automotive, construction, and electronics.
