Abstract

The invention provides a preparation method for a carbon fiber trim strip for an automobile. A carbon fiber fabric layer with excellent properties is obtained by optimizing the weight ratio of a curing agent to resin in a resin mixture containing the curing agent and the weight ratio of a carbon fiber fabric to the resin mixture containing the curing agent. Compared with the prior art, the preparation method disclosed by the invention has the advantages that the process is simple, equipment investment is less, the resin content of products is high, and the products are good in corrosion resistance; the carbon fiber trim strip can completely replace a plastic interior trim strip; compared with a plastic product, the carbon fiber trim strip has the characteristic that the weight is reduced by about 50 to 60 percent; the grade of a complete automobile and the competitiveness of the products are improved, and the individualized demands are met.

Description

Technical field [0001] The invention relates to the field of automobile interior decoration, in particular to a method for preparing a carbon fiber decorative strip for automobiles. Background technique [0002] Carbon fiber is a new material with excellent mechanical properties. Its specific gravity is less than 1 / 4 of that of steel. The tensile strength of carbon fiber resin composite materials is generally above 3500Mpa, which is 7-9 times that of steel. The tensile modulus of elasticity is 23000. ~43000Mpa is also higher than steel. [0003] However, carbon fiber materials only show high strength along the fiber axis, but have poor impact resistance and are easily damaged. Therefore, when manufacturing structural components, they often take advantage of their tensile strength and light weight to avoid making the side surface. The impact part. It feels similar to plastic, but has the same strength and toughness as steel. Carbon fiber components can not only help the vehicle ef...
