OBJECTS OF THE INVENTION: TECHNICAL FIELD The present invention relates to a "vacuum-assisted resin-assisted resin infiltration molding method for coating-free composite materials", and particularly relates to a vacuum-assisted resin infiltration method to produce a smooth surface without A method of manufacturing a pinhole composite product. [Prior Art] According to the 'fabrication method of manufacturing composite products, there are many ways to make a composite product. If the composite product is made by hot pressing, it will make the surface of the product produce a hollow hole, and manufacture. In order to beautify the surface quality of these products, it is necessary to supplement the subsequent soil filling, painting and other processes, and fill in the holes, so that it can be produced in large quantities. Cost, resulting in lower competitiveness. Yes, fortunately, if the composite product is made by vacuum heat forming, although J is built to better surface quality, it is only necessary to use #g @ ϋ Α β π" temple method still needs to use prepreg and it is expensive. , forest equipment to transfer benefits; ^ cost ^ 'and the cost of the work has to make it into - money into the two must. ' _, all kinds of missing, things::=: There are still areas for improvement in the past, so we will take care of the problem and think about the improvement method. In the case of the current manufacturing, we will create a coating-free coating. After many improvement tests, the infiltration method was finally infiltrated. SUMMARY OF THE INVENTION In view of the above, the main object of the present invention is that the surface quality of the product is relatively high, and that the vacuum-assisted resin infiltration operation of the long-supply type can not only achieve the manufacturing cost, but also a large amount of body-saving pattern and high strength. The quality of the yarn is specially established in order to achieve the above-mentioned method. The lipid permeation molding method comprises the following steps: a kind of artificial auxiliary tree is arranged in the layer of the layered fiber material. The layer 4 is arranged; the U first (four) several ages are on the top of the mold t := ίί:: "Steps: the vacuum envelope is installed in the mold has the same - the first '33;' and the bottom sides of the vacuum envelope are divided into the "vacuum" step: the brake vacuum; using the first tube will In the mold, in the "vacuum-assisted resin infiltration molding" step, the resin is injected into the second tube from the second tube. In the "heating and heating" step: the heating and heating work is carried out; When the fiber material is in the "release" step: after the mold is removed, the finished product in the mold is taken out. The second and second seals are taken out, wherein the mold is a metal material or a composite material. Among them, the fiber material can be in the form of a dimension. Riding fiber, _ fiber or ke vera fiber, the weaving type of Qianwei material can be plain weave, woven weave or twill weave 200916305 weaving ', , middle ' the tree can be epoxy resin or unsaturated polyester Resin, etc. In the following, the drawings of the preferred embodiments of the present invention are further described in order to enable those who are familiar with the present invention to be able to implement the instructions according to the description of the present specification. [Embodiment] Recording Γ Γ ' 'Please refer to the first to the first figure, the present invention is an auxiliary resin infiltration molding method, wherein the molding method comprises the following steps (as shown in the first figure): In the "stacked fiber material" step: a plurality of fiber materials are prepared in advance to be stacked in the cookware 20 (as shown in the second figure); in the "install vacuum envelope" step: the vacuum seal bag 3q is installed The surface of the mold i (4) can cover the fiber material, and the surface of the vacuum envelope 30 has a first tube 31 and a second tube 32 (as shown in the third drawing in the "vacuum" step When the first tube 31 is used to evacuate the mold (as shown in the fourth figure); , /, 20 in the step of the second auxiliary resin infiltration molding: the resin is from the second tube 32 in an ancient manner. Injecting the impregnation (as shown in Figure 1), because the hardening process is carried out in the vacuum envelope 3 (ie, no, under), the organic compound that is volatilized escapes into the air, and the environment is reduced. The health impact is reduced; the proportion of the heart is greatly in the "heating" step: The resin in the mold 2 and the fiber 200916305 material ι ° & into the heating operation (as shown in the sixth figure); take out d; the mold 2 ° top surface of the vacuum envelope 3. (After the nth Γ 'after', the finished product in the mold 20 is not taken into the map.] Thus, the process of the present invention is completed. ^, the mold 2 is a metal material or a composite material; The fiber material 1 can be a woven fiber type of a disc fiber, a glass fiber or a velvet braided fiber material. The woven type can be plain weave, woven or slanted, and the resin can be epoxy resin or unsaturated poly g. Resin, etc. By the above-mentioned molding method, please refer to the first to ninth drawings. The present invention mainly prepares a plurality of fiber materials 1G in advance in the mold 2, and arranges them in a vacuum envelope. 3〇 is installed on the top surface of the mold 2〇, and can cover the fiber material 10, and the bottom surfaces of the two sides of the vacuum envelope 30 respectively have a first official 31 and a second tube 32, and then, the first tube 31 is utilized. The inside of the mold 20 is evacuated, and the resin is injected and impregnated from the second tube 32 by vacuum assist, after which The resin and the fiber material in the mold 20 are subjected to a heating and heating operation. Finally, the vacuum envelope 30 of the top surface of the mold 20 is taken out, and then the finished product A in the mold 20 is taken out; since the present invention mainly utilizes vacuum Manufactured by VARTM (Vacuum Assisted Resin Transfer Molding), which is a resin transfer process (Resin)
