Description of the invention: [Technical field to which the invention belongs] _ 目 目 目 目 目 目 目 目 目 目 目 目 目 目 目 目 目 目 目 目 目 目 目 目 目 目 目 目 目 目 目 目 目 目 目 目 目[Prior Art] The composite material is composed of two or more materials, the main strength of which is derived from the addition of ===, etc., and these reinforcing materials are formed into a whole by, for example, a ring or a material. Composite material - a designable material ====, reinforcement and substrate. For example, if the coffin temple with nuclear fat-trapping composite material has a good ΪΪ5矽? dimension with phenolic resin composite linings 'good, ΐ excellent Ϊ mouth: application, depending on the different parts, the material . The former _ dimensional reinforced resin composite material: with continuous i-dimensional pre-impregnation iil: two gram fiber type, commonly used short-fiber molding materials consider the use of short-fiber molding materials, so that the two are not long w, hundred precursors simple, It can manufacture complex shapes f hot f press forming, low manufacturing. When the structural strength requirements are high, or the cost of the burning work is more satisfactory, the short-fiber material cannot be used to arrange the length and length of the fiber. The longer the fiber is continuous, the better the reconstitution strength of the Xiesheng Yuexue and the burnt character, but the difficulty in making the product is better, and the better, the better, and the better. A typical long-fiber conical tube 5 200812788 piece, such as the US NASA document PD-ED-1218 "Application of Ablative Composites to Nozzles for Reusable Solid Rocket Motors j, the rocket engine nozzle expansion section composite insulation member, in order to arrange the fibers It meets the requirements of a specific angle and is manufactured by the tape winding method. The step is to use a tape wrapping machine to form a fiber-reinforced resin prepreg with a fiber-woven fabric, which is parallel to the axis (called parallel tape winding method). Or the angle of the clip (called the oblique tape method), wrapped around the mold = outside. The inclined tape wrapping method needs to use 45. The mitered prepreg woven tape is more costly, so the fiber angle of the design of the heat insulating member can be In the case of acceptance, it is economical to use the parallel tape winding method. Regardless of the parallel tape winding method or the oblique tape winding method, the angle between the fiber arrangement direction and the axis is not large (generally not more than 45), and it is difficult to establish the molding pressure by molding. Therefore, most of them use pressure or hydraulic shovel, using flow ^, vertical lateral force, which must be in accordance with the vacuum bag procedure, the release film, the absorbent cotton and the vacuum bag, the aforementioned entangled embryo The material and the mold core (male mold method) are placed in the autoclave, vacuumed and pressurized and heated. The procedure is far more complicated than the compression molding. The whole wrapping pressure g program is shown in the first figure flow. The material formed by the male mold method produces wrinkles, and often causes colloid concentration, cracks, etc. The degree of wrinkles is related to the thickness and size of the finished product, and the smaller the radius of curvature of the finished product is J. Wrinkles (4) The degree of local low density may cause a lot of factors, including material characteristics, entanglement % and temperature and pressure conditions of autoclave molding, and these, the degree of reading (four) is equivalent to the position of occurrence. The randomness, resulting in 』 ^ 5 rate and quality is not easy to control. US ΑΙΑΑ 89 24ι8,

In addition, the sensitization and reconciliation 4 to avoid product shortage, must increase the thickness of the billet:: Further progress affects the quality and pass rate, causing a vicious circle, and the wave = the time of the repairer to increase manufacturing costs.

However, the use of hydraulic = and miter shifts will significantly increase production costs. The most 々^^, the Chinese manufacturer of the 2G1585 patent, the "manufacturer of the beveled dimension i" is a kind of manufacturing method by the molding method. * More than the q4S^ piece of money, the fiber can be made. The heat is recorded to a large angle of pressure, and the 1 is suitable for molding. It provides more than 2 () _si in the forming of the plate axe! It will record heavy wrinkles, and there is very little colloidal assembly pressure direction and axial direction. When the refresh angle is less than 45, it is still not suitable for forming the entangled billet by the molding method, and it can be formed at the lowest cost. _ Detailed analysis of the cone material _What shape i entanglement of the billet 'Converting the axial force into the lateral pressure and then matching the appropriate temperature control can produce high quality. [Inventive content] The purpose of the invention is to provide a wrap-around cone-shaped material-filled tube fitting k method. It is not necessary to use vacuum bag packaging materials such as an autoclave or a hydraulic squeegee, such as an expensive suction brocade, a release film, etc. It is known that the tape-type tapered composite pipe is generally hot pressed according to the method of the present invention. Molding without the need to design complex side pressure generating mechanisms. The method of manufacturing the ribbon-shaped conical composite pipe fittings has no enemies on the mouth surface, and the fibers are arranged neatly and meets the design requirements.

Among them, the design of the hot stamping mold is such that: (1) t type ίί, the slanting surface of the raw material is in contact with the die surface before the upper and lower end faces. After the lateral pressure is established, the hot stamping mold is closed; after being moved (2) ίί, there are enough _ points in the various points to make the finished parts meet the required solution.

The slitting machine cuts the carbon fiber field resin prepreg into a strip of material of a certain width: size), and winds it around the mold core 2 For example, in the second, second, and third waters, the hatching indicates the direction in which the fibers are arranged. In this example, the parallel entangled plates are _ red __ blanks 7 .攸; = 模 = lower embryo == 2 = no 疋 position pin, ejector plate, ejector pin hole, top splint: bottom clip 'and other 'pressure 8 200812788 === before pressing, wrap up and on The relationship between the children and the children. As shown in the figure, the lower end face of the blank is held under the i* and the straight upper inclined surface of the upper end surface 12 of the blank and the upper surface of the upper mold 10, the shaved hot thin m+ the upper H-side has a _ slope Above weight = axis, when moving down, 'there will be enough _ compression for each part of the billet.

After the fourth_shower is closed, the relative position of the front upper die '9' is indicated by the dashed line 16 in the figure. The figure shows that the lateral direction of the blank 7 is considerably compressed, the shoe is set, and the setting is set. Molding; After clamping, start to heat up to the fifth figure, -1^15 top to get the finished product. The whole process of the singular-viewing process, such as the entanglement of the entanglement of the method of the Li multi-graph, shows that any of the tape-wound tapered composite pipe fittings of the present invention can be inspected smoothly without any X-shaped repairs. The arrangement is quite neat. In order to pressure the full financial thief, Guan Yi made the law, but the speculation of the finished product, 3 疵.
