Problems solved by technology
[0003] The car roof is a large area of vehicle materials, and there are many interior decoration parts. According to the design and application of the existing car roof, especially for commercial vehicles, hemp fiber composite boards, PP glass fiber composite boards and fabrics are mainly used for heating and forming. This type of molded product is heavy, load-resistant and light, and has poor comfort properties such as sound insulation
Foaming composite technology is one of the preferred technologies to solve the application of lightweight materials, but the simple foaming technology is difficult to meet the strength properties of the material such as load resistance and bending resistance under the premise of achieving a relatively light density at the same thickness of the material
