Abstract

The invention relates to an automobile exterior trimming part based on an enhanced carbon fiber composite material plate and a preparation method of the automobile exterior trimming part based on the enhanced carbon fiber composite material plate. The automobile exterior trimming part based on the enhanced carbon fiber composite material plate is characterized by comprising an upper cover plate layer, a lower cover plate layer and a middle bonding layer, wherein the upper and lower cover plate layers comprise thermoplastic fiber reinforced laminated composite material plates, the middle bonding layer comprises a plastic layer or a foam resin layer, the upper cover plate layer, the lower cover plate layer and the middle bonding layer are integrally connected through a mould pressing manner; the middle bonding layer is solidified at room temperature while performing mould pressing to form a bonding connection structure of the upper cover plate layer and the lower cover plate layer to enhance the rigidity and strength of the product. According to the invention, the thermoplastic fiber plates are utilized for processing to simplify the manufacturing process of the product so as to improve the efficiency and reduce the cost; an upper cover plate and a lower cover plate are bonded by using foaming resin, and taken as reinforced layers to improve the rigidity, strength and impact resistance of the product so as to achieve a damping effect.

Description

technical field [0001] The invention relates to a method for preparing a carbon fiber automobile exterior trim, in particular to an automobile exterior trim based on a reinforced carbon fiber composite material plate and a preparation method thereof. It belongs to the technical field of auto parts. Background technique [0002] At present, with the improvement of emission standards and the increasing pressure of energy saving and emission reduction, domestic and foreign automakers are focusing on reducing the weight of the car body. It is an effective way to use high-strength materials such as carbon fiber composite materials in the design and manufacture of car structures. weight-loss measures. The application of carbon fiber composite materials can greatly reduce the weight of the vehicle body, and it is expected to reduce the weight by more than 50%. [0003] As one of the important components of automobiles, automotive exterior parts are mainly prepared in two ways: pr...
