Description of the invention: 'Technical field to which the invention belongs>> The present invention belongs to a composite structural member process and its structure, and is mainly used in the manufacture of thermosetting composite structural members, which can be improved in addition to reducing manufacturing procedures. The strength and toughness of composite structural members improve product yield and have significant practicality and progress. [Prior Art] According to the manufacturing method of the existing thermosetting composite structural member, in particular (in the manufacturing process of producing the thermosetting composite structural member by the mold, the composite material is first coated with a soft inflatable bag, and reserved The gas nozzle for inflation is placed in the mold, and after the mold is closed, the heating oil pressure platform is placed, the mold is clamped by oil pressure, and then inflated into the air bag of the coated composite material, so that the composite material is attached to the mold. The surface is heated by the oil pressure platform to solidify the thermosetting composite structural member, wherein in order to match the shape of the composite structural member and avoid the breakage of the airbag during the inflation molding process, the defective structural member is produced. Generally, a plurality of air bags are required. As shown in the sixth figure, the air nozzles 46 of the plurality of air bags disclosed in Announcement No. 210310, "Method for Manufacturing a Composite Bicycle Rack" are connected to a plurality of air bags J 41, 43, 45, 47, so before the molding, it is necessary to pre-produce a plurality of air bags, the production process is extremely cumbersome. [Summary of the invention] (The technical problem to be solved) The program is cumbersome, and the air bag itself only provides the function of inflation and expansion. Because the shape is complicated and cannot be taken out after molding, most of the thin plastic materials are used to avoid adding too much weight, and the structural strength is not enhanced. 200914240 (Solution Technical means) In order to simplify the preparation process of the air bag described above, and to fully utilize the air bag, the characteristics of the structural member cannot be taken out, and the present invention pre-forms the shape contour of the inner part of the structural member into a whole inner casing, and Only one inflating hole is retained, and then the thermosetting composite material is coated on the outside of the preformed inner casing, placed in the mold, placed in the heating oil pressure table, and inflated against the inner casing of the preform to support the shape of the inner casing and The inner shell supports the outer thermosetting composite material, is attached to the mold, and is solidified by heating, that is, the required composite structural member is completed, and the inner shell remains the same in the composite structural member, but because of the shape The contour is consistent with the structural parts, and the plastic material used in the selection can provide different degrees of structural strengthening effect. 'Embodiment】 Please As shown in the first to fourth figures, the invention relates to the process and structure s of the composite material structural member, and the main processes thereof are as follows: 复复 A. Pre-formed with a plastic material and a structural shell 10, within The shell 10 is connected to an inflation port 2; the inner B. is coated with a predetermined thermosetting composite material 30 in the inner shell. The solid composite material 30 may be a carbon fiber of a prepreg resin or a prepreg fiber such as a glass fiber or Pre-impregnated woven fiber cloth; a C. The above-mentioned coated thermosetting composite material 3 预 pre-J (two) with 50 ′′ and the mold 5 〇 is clamped to the heating; D· by the inflation port 20 added to the preset pressure, support 10 , the thermosetting composite material 30 is attached to the mold 5〇; ^ 模具·Mold 50 is thermally conducted to the thermosetting composite material 3〇, and is formed into a thermosetting composite structural member; the solid inner shell 10 can be thermally consolidated. Material structure parts 200914240 « Structural design, choose different plastic materials, you can choose HDPE, .NYLON, PE, PVC, PET, PEEK, PC, ABS, or other thermoplastic; materials, in addition, the above casing 10 can also be pressurized Change to solvent heat Pressurizing the inner shell is formed inside the pressure, after the molding the inner housing 10 as completely fit the shape of the contour made structural member of, can enhance the structural strength and toughness, by the choice of plastic material and can provide different degrees of structural reinforcement efficacy. In addition, as shown in FIG. 5, a cross-sectional view of a composite trifurcated structural member formed by molding the present invention in the mold, wherein the inner casing 10 is identical in contour to the structural member, and is inflated by the inflation port 20 in the mold 50. The inner casing 20 is supported, and the thermosetting composite material 30 is attached to the inner surface of the mold 50 for heating and molding. The inner casing 20 is directly attached to the mold 50 at the outlet of the three fork tubes in the mold 50, and is formed after molding. In use, the inner casing 20 of the nozzle portion is cut away and retained in the inner casing 20 inside the composite structural member. In summary, the "composite structural member process and structure" disclosed in the present invention provides a special method for simplifying the manufacturing process of the composite material structure of the blown inner bag, and further strengthens the strength of the structural member by using the blown inner shell at the same time. And toughness, and to obtain a practical high composite y component and its required process, so that the whole is indeed practical and cost-effective, and its structure has not been seen in books or public use, in line with the invention For patent application requirements, I would like to ask the Bureau to give a clear understanding of the patent.
