Since the birth of the first real car, it has a history of more than 130 years. With the continuous development and progress of automotive technology and performance, the design of the interior of the car and the use of materials are constantly changing and upgrading. If the shape is the image and appearance of a car, the interior reflects the character and connotation of a car. So, since the development of automobiles, what changes have taken place in the interior materials, and what new materials have been used in automobiles?



In the early stages of automobile development, the industrial level was low, and the types of synthetic materials were relatively rare, so natural materials were the first to be used in automobiles, one of which was natural leather. In the early days, first-layer calfskin, which is what we call Nappa leather today, was widely used in vehicle seats. The first layer of cowhide is also recognized as the most luxurious and noble decorative material. With the continuous improvement of the industrial level, a large number of man-made materials continue to emerge, and the number of people raising calves for food is also decreasing. As a result, the current low-end cars rarely carry expensive first-layer cowhide materials. Instead, use cheaper artificial leather or fabric instead.

·Plastic, slush molding (PU, PVC, ABS, PP)

Plastic material is currently the most widely used material on vehicles, and plastics can be found on almost every vehicle. Common plastic materials are mainly divided into four categories: soft polyurethane (PU), polyvinyl chloride (PVC), acrylonitrile/butadiene/styrene terpolymer (ABS), polypropylene (PP). According to the molecular structure and thermal properties of the resin, plastics are also divided into thermoplastics and thermosetting plastics. Most of the plastics commonly used in automotive interiors are thermoplastics. Among them, the slush molding material commonly used on the dashboard is a kind of plastic, also called coagulation molding. It uses PVC and ABS materials, and then injects some PU foam to enhance the resilience; the door inner panels mostly use ABS or Modified PP material is injection molded; the steering wheel is generally made of semi-rigid PU foam, and the steering wheel covering is mostly made of PP, PU, ​​PVC, ABS and other resin materials.

·Metal (chrome)

Metal is also an indispensable element in the interior of a car. Chrome decorative strips and brushed chrome metal panels are used in a large number of models to embellish the car. At first, the use of metal decoration in the car was purely for aesthetics. With the increasing use, the advantages of better heat resistance and low friction coefficient gradually emerged. At the same time, the chrome-plated decoration parts can maintain the smoothness for a long time and are not easy to wear and corrosion. This is why the door handles that are repeatedly pulled and rubbed by human hands are covered with chrome.
