Fender for automobile and manufacturing method thereof

Abstract

The invention discloses a fender for an automobile and a manufacturing method thereof. The fender for the automobile comprises a bottom layer and a surface layer, wherein the bottom layer and the surface layer are compounded by a needling process, the material for the surface layer comprises a surface layer main fiber and a surface layer bonding fiber, and the material for the bottom layer comprises a bottom main fiber, an auxiliary fiber and a bottom bonding fiber; and the melting point of the surface layer bonding fiber is lower than that of the surface layer main fiber, and the melting point of each of the surface layer main fiber and the surface layer bonding fiber is lower than that of the bottom main fiber, so that the bottom main fiber does not melt when the surface layer main fiber, the surface layer bonding fiber and the bottom bonding fiber are melted. According to the fender for automobile, the surface layer and the bottom layer are made of fiber materials with the sound absorption effect, and through heating the surface layer fibers to be in a molten state, the surface becomes smoother after cold roller shaping, and therefore the overall structure becomes porous, smoothand hard, and the fender can has good sound absorption property, anti-icing property and impact resistance..

Description

technical field [0001] The invention belongs to the technical field of automobile exterior decorations, and in particular relates to a fender for automobiles and a manufacturing method thereof. Background technique [0002] The fender is installed on the top of the car tire and under the sheet metal. It belongs to the exterior decoration of the car and can be used to block tire noise, rain, and mud. During the driving process of the car, the friction and impact between the tire and the road surface produce noise, which seriously affects the driving experience of the vehicle. At the same time, some countries have added external noise to vehicle exterior trim regulatory requirements. In addition, when the vehicle is driving in ice and snow weather, the ice and snow are easily adhered to the fenders under the drive of the tires. When the ice layer is too thick, the moving tires will hit the fender when it shakes up and down. On the other hand, the fender is too heavy and easy...
