Description

Composite component, preparation method thereof and window assembly comprising composite component Technical Field The invention relates to the field of materials, in particular to a composite component comprising a semi-reflecting layer, a preparation method thereof and a window assembly comprising the composite component. Background In the field of electric automobiles, thermal comfort is always a central subject. The method is directly related to the driving experience of the user and is closely connected with the driving mileage of the vehicle. The effect of the window body as a key element affecting thermal comfort is not so small. Especially on sunny days, the influence of the window on the internal heat environment of the vehicle is more remarkable because of strong sunlight. Consumers desire a better thermal comfort experience than existing products through the application of new technologies. In addition, vehicle appearance has also been another core element of consumer concern. In the design of vehicle appearance, it is important to avoid the problem of light pollution of the vehicle window body due to specular reflection. The strong specular reflection not only affects the use experience, but is more likely to jeopardize driving safety, and therefore, for automotive window designs, there is also a need to control the light pollution of the window. In addition, some consumers also dislike an excessively shiny vehicle appearance, and they expect a more visually pleasing design. Providing an infrared reflective (IRR) coating on glass, such as float glass, is one of the prior art techniques for controlling thermal comfort. The IRR coating has very low reflectivity in the visible light range, so that light pollution can be effectively controlled, but the visible light accounts for about 43% of solar energy on the earth, so that even if a complex laminated design is adopted in the technology, the technology still faces the upper limit constraint problem in the aspect of heat resistance. In addition, the high cost of infrared reflective coatings also limits the application of this technology. Conventional automotive window designs suffer from various degrees of limitations and disadvantages in terms of environmental thermal comfort control, light pollution control, visual appearance, and cost. Accordingly, further research and development work is still being conducted to obtain more desirable window materials.
