[Prior Art] With the advancement of technology and society, people's requirements for products are gradually changed from the requirements of products to the requirements of products with light weight, small size, high strength, long life and so on. Therefore, in recent years, related companies have been racking their brains and developing a variety of emerging materials that are sufficient to meet people's needs. © Referring to Fig. 1, the more common emerging material is carbon fiber sheet 1, which comprises a plurality of layers of carbon fiber prepreg 11 impregnated with resin. When the predetermined product is formed by using the carbon fiber sheet i, the carbon fiber sheet 1 is placed in a mold, and hot pressing is performed to melt the resin in the resin-impregnated carbon fiber prepreg n, and the impregnating resin is applied. The carbon fiber prepreg u is closely bonded and hardened to form a product of a predetermined shape. Because of the light weight, high strength and high rigidity of the carbon fiber sheet 1, the carbon fiber sheet 1 is gradually replaced with a metal material. β However, due to the limitation of the characteristics of the carbon fiber sheet 1, the product having the predetermined shape by the carbon fiber sheet 1 has the following disadvantages to be improved. 1. The surface of the product is not good. · Because the pores of the carbon fiber prepreg 11 are large, When hot pressing, it is easy to cause the loss of the molten tree in the carbon fiber prepreg u on the surface of the carbon fiber sheet 1 and the formation of many depressions or potholes on the surface of the product affects the quality of the product. 5 200948605 2. Molding procedure is complicated: the smelting resin lost from the carbon fiber prepreg 11 during hot pressing often remains at the junction of the periphery of the product, so that the products formed by the broken fiber sheet work often need to pass through The post-treatment process removes the resin remaining on the outer periphery of the product, and the molding process is complicated to increase the production cost. Therefore, how to prevent the sap of the resin-impregnated carbon fiber prepreg 11 from being lost during hot pressing to effectively improve the surface of the product and simplify the molding process has become a problem that the related industry desires to actively improve. [Explanation] Therefore, the main object of the present invention is to provide a decorative substrate which can prevent the loss of tree stalks and effectively improve the appearance of the surface of the product and simplify the manufacturing process.
