', [First technology] :: m The application of composite materials is widely seen in various needs for lightweighting and materials. Currently, it also partially replaces metal / and is used in the people's livelihood industry, sports equipment, automotive industry. 'Χ' composite materials can have high strength, and the fiber is among the two = ... 'These reinforced fibers include carbon fibers, graphite fibers, fibers, carat fibers, and other organic or inorganic fibers. -The recognition of fibers is only related to the different grades or different types of fibers under different process conditions. == Different in mechanical strength, thermal conductivity and electrical conductivity ;: Composite materials ::: Pipe joints, different manufacturing methods, and materials The official joint of 官 has a far-reaching influence. The setting, =: shown is a traditional fitting made of composite materials. 糸 The connecting piece (") is fixed to the rod (70) by a lock ("). Form the basic form of the pipe joint, and the surface of the rod (200426026 connector (7 1)) is covered with a mating half shell (7 3). After the composition, the surface of the half shell (7 3) is pasted. Cover the composite material, and add # to the thermal plastic film, so that the thermal plastic film is heated and compressed to locate the beam-shaped composite material, wait until the composite material is cured, and then separate the connecting member (7 1) and the rod member (7 0) The force mouth is drawn out, and the solidified composite material is taken out of the mold: the half shell (73) is taken out, and a hollow pipe joint is formed to provide pipe fittings. The above-mentioned traditional composite pipe joint manufacturing method, because Thermoplastic film itself is an elastomer, and its relative shrinkage and compression of the composite material are difficult to form a flat surface, and it is easy to produce wrinkles. Therefore, it needs to be ground and polished to achieve commercial requirements. However, Composite materials formed into pipe joints After grinding and polishing, the composite material will be damaged, and the mechanical strength and quality of the finished product will be difficult to grasp due to secondary processing on the surface of the finished product. [Summary of the Invention] In view of the above problems, the inventor thought and innovative design, And developed a composite thin-shell joint and its manufacturing method ", which can produce a thin-shell joint with a flat surface without further processing, to ensure that the quality of the composite material is easy to grasp and achieve the effect of meeting the designer's needs. The technical content to achieve the above purpose is to provide a "composite material> manufacturing method of special shell joints". The manufacturing steps include: the first step, which uses separate support rods to form a joint-shaped assembly; the second step, The composite material, the expansion material and the composite material are sequentially pasted on the surface of the laminated jig, and the composite material; in the third step, the mold is placed in a mold and added, and the support rod is drawn into the thin shell joint. In step 4, the surface is coated with a plurality of heat-hardened layers. In the fourth step, a layer is formed, and a laminated mold having a plurality of layers of composite material is formed. Then, a composite material layer with multiple layers is taken out. The structural feature is to provide a "composite material member", which has a plurality of layers of composite material, and sandwiches the closed expansion material between the inner and outer composite cavities. The thin shell joint made by the above method can achieve the surface flattening effect, so that the quality of the joint product can meet the designer's requirements, so as to give full play to the material characteristics of lightening and better mechanical strength of the composite material. [Embodiment] The manufacturing steps of the method of the present invention, which can be coordinated with reference to the first to sixth figures shown in FIG. 5 include: The first step (A), forming a joint-shaped assembly composed of independent support rods (10). Laminated jig (1); the independent support rod (10) can be a solid metal rod or a hollow tube, and its surface can be coated with a layer of nylon film (1 1) for release purposes After the composite material and thermoset molding, each independent supporting rod (1 0) can be easily pulled out, and a positioning hole (丄 2) is provided at the end of the supporting rod (1 0), and the laminated jig (1) can be bolted. (1 3) Insert the positioning hole (1 2), and position the laminated jig (1) on the fixed seat (20); the second step (B), apply the composite material (30) to the laminated layer Rule 200426026 (1) surface, such as carbon fiber material or glass fiber material, can be made to adhere to the surface of the laminated rule (Ί, Ben Yunfang k 1), and placed on the surface of the composite material 30) Resin series expanded material (foamed) ('Furthermore, the surface of the expanded material (31) is covered with composite material (3 /, plural Next, the composite material (30) and rq 9 彳 are formed (3 丄); (3 2) the third step (C) of clamping the closed expansion material, and the surface is laminated with the multilayer composite material (32). Put it into the mold (40) and harden it to expand the thermal expansion of the expanded material (Sichuan Yu composite material (30, 32), and use the expanded material (3 J) layer of the composite material (30, 32) against the inner layer and the outer layer) The inner surface of the inner composite material (30) can be densely pressed against the surface of the support rod (## r.9, „〇〇0), and the outer composite material (32) can be closely adhered to the mold ( 4〇) Mould 4.1) Inner wall surface;, ^ Four steps: After the thermosetting molding of the above steps, the composite material (30, 32) is thermoset into a support rod (10), and a flat surface is formed. The structure of the joints (3). The thin shell joints made by the doubling brother's example are formed with multiple layers: and the closed, expanded material is sandwiched between the square, inner and outer layers of the joint material, =: piece solid And the composite material made by the method of the present invention :: the expansion material in the thermoset molding expands and resists inward and outward, so that the inner :: composite The outer surface of the material can be densely combined with the surface of the supporting rod and the mold and the eight inner surfaces to achieve the flat surface of the finished product, so that the quality of the finished product 200426026 can meet the designer's requirements, and it can avoid secondary processing causing duplication.
