Problems solved by technology

[0004] However, the known decorative part C is combined with the exterior trim panel c1 by embedding the nut c3 or injecting screw threads, etc., but the exterior trim panel c1, the column c2, the nut c3, etc. are different. The bonding strength of the material is quite weak, and its resistance to pull-out (external force borne by the nut after assembly) and torsion resistance (force borne when combined with the bolt) are insufficient, resulting in that the column c2 and the nut c3 are easily detached from the The exterior decorative plate c1; moreover, the nut c3 has a large error in the inner diameter of the screw hole c31, and the positioning of the screw hole c31 on the mold positioning column c4 often has inaccurate situations, such as Figure 9 As shown, the position embedded in the cylinder c2 is easily misplaced, resulting in defective products

Embodiment Construction

[0060] See first Figure 1 to Figure 3 As shown, it is a kind of automotive trim manufacturing process A of the present invention, which includes: a preforming step (a), first cutting the soft composite material cloth (or carbon fiber cloth) into at least one outer layer of the desired shape Cloth 10 and an inner layer cloth 20, and the inner layer cloth 20 must have at least one perforation 21, and the inner diameter d of the perforation 21 is smaller than the outer diameter D of the flange portion 42 of the binding member 4; a first forming step ( b), the outer layer cloth 10 is placed in the upper mold 6 and the lower mold 7 for molding, that is, after being pressurized and heated, it is placed in the mold and the composite material cloth or carbon fiber cloth is solidified and demolded to obtain a hardened outer layer 1 , and the hardened outer layer 1 can be made by impregnating or injecting glue; a second molding step (c) is to place the hardened outer layer 1, the inner...

Abstract

The invention provides an automobile decorative part and a manufacturing process thereof. The manufacturing process comprises the steps that an outer layer of at least one composite material is laid in a mold and cured to form a hardened outer layer, at least one bonding piece penetrates through perforated holes in inner layer cloth of the at least one composite material, a flange part of the bonding piece is located between the hardened outer layer and the inner layer cloth, and then curing molding is conducted in another mold to obtain a decorative part finished product; the decorative partis installed on a vehicle body or rims by using a fastener to achieve the purpose of taking textures of the composite material as surface decoration of the vehicle body or the rims.

Description

technical field [0001] The invention relates to the technical field of combining composite materials and other dissimilar materials to form decorative parts for car bodies or rims, in particular to an automotive decorative part and its manufacturing process. Background technique [0002] Composite materials have the characteristics of light weight, high strength, corrosion resistance and beautiful texture, so they are widely used in decorative purposes. [0003] see Figure 8 and Figure 9 As shown, a known decorative part C is disclosed in U.S. Patent US2016107339A1 (the patent name is: COMPOSITE MATERIAL MADE ORNAMENT, A MOULD ASSEMBLY AND A METHOD FOR MAKINGTHE SAME), including: on the inner surface of a base material of an exterior decorative panel c1, Two cylinders c2 are formed, and the two cylinders c2 are inserted into the two predetermined through holes on the outer surface of the vehicle, and a nut c3 is embedded in each cylinder c2, and a bolt is respectively pas...
