Description of the invention: [Technical field to which the invention belongs] The present invention relates to a separator sheet element for porous fragrant materials that are separately stacked during the manufacturing process. A particular example of the present invention relates to a carbon annular separator element for annular composite preforms that are stacked separately, especially during a densification process, such as chemical vapor infiltration (CVI). Composite preforms can be particularly annular preforms used in the manufacture of brake discs or other friction elements. [Prior art] Bifurcation of ring-opening / preforms to manufacture brake discs and similar devices is disclosed in U.S. Patent Application No. 10/468, 〇31, filed on August 14, 2003; Its representative is shown in FIG. 1. Fig. 1 is a high-level illustration of a processing chamber having an enclosed space 10, which contains a ring-shaped preform or substrate 20 filler made of carbon fiber. The filler is in the form of a substrate f sheet group, and the substrate has center centers f which are generally vertically aligned. The film group may consist of a plurality of stacked film group regions separated by one or more intermediate carriers 12. . The stacked substrates are separated from each other by a spacer 30. As shown in FIG. 2, the spacers 30: k-direction cloth i 'and their number can be changed. They provide (,) a gap 22 of substantially constant height between the lamination stacks between adjacent substrates, and at the same time make the inner volume 24 of the lamination stacks (composed of the center channel of the substrate generally aligned) and Outer stack 4 communicates with the external volume inside the enclosed space. In the example of FIG. 1, the enclosed space 10 contains a single substrate stack. In a variant, multiple bases can be arranged side by side in the same enclosed space. 93555.doc 200538279 The enclosed space 10 is heated by a pedestal 14 (for example, made of graphite), and the pedestal w is used to define the enclosed space 10 and outside the casting 17 around the pedestal = ^ 应 4 Coil 16 is inductively coupled. Other heating methods can be used, such as resistance heating Z-ear effect). ^ A The gas containing one or more carbon precursors is brought into a closed space, and is a hydrocarbon gas, such as sintered and / or ethane. In the example shown, the entry through the seal, the bottom 1Ga of the space. The gas passes through the preheater area 18 formed by a single or multiple disks. The disks are placed at the bottom of the enclosed space at a height J, and are supported under the disks. The gas heated by the pre-heater plate (rising to the existing temperature in the enclosed space) flows freely into the enclosed space, while passing into the internal volume 24 ', into the external volume 26, and into the gap 22. Residual gas is extracted from the enclosed space by suction through an opening formed in the cover. The spacer 30 is a separately placed block element and is most often made of an oxidized inscription. However,-once the 'oxidized sintered element is brittle', the loss from self-fracture is high. In fact, in normal use, the conventional alumina block usually lasts no more than 2 or 3 densification cycles. This naturally increases manufacturing costs because the aluminum oxide block must be replaced. In addition, a separate oxidized ingot element and a waste temple are appropriately manually placed between each preform layer. Fig. 2 shows an example of 6 such block elements, and 12 blocks are actually implemented / used. The time burden is not required for processing fragile pieces without breaking: Aggravation ° Usually 'complete' densification processes containing 7 preform trays (each with 12 to 14 pre-riser groups) may take one or more It takes two working days to establish according to the conventional method. Another problem associated with the use of a single spacer element 30 is that they tend to deform (actually recessed) the preforms (and spacers) due to the weight of the preforms (and spacers) piled up as described above. As can be understood from Fig. 2, there is a large unsupported area of the preform between the spacer elements 30 on the circumference. Since the preform material is generally easy to bend, and since the spacer element 30 composed of alumina is not deformed, the depression occurs on the surface of the preform corresponding to the position of the spacer element:. Although slight, these deformations must be machined in additional steps to obtain the required flat surface for friction applications. Therefore, the thickness of each preform is thicker than required for the final product. The deformation is expected to occur in known processes and removals. These deformed final machining steps. Materials that are machined and dropped represent economic waste. [Summary of the Invention] As mentioned above, the present invention relates to a ring-shaped separator element for separately stacking single sheets or other units. The H-piece separator element according to the present invention has a generally flattened annular shape having opposite first and second surfaces. At least one surface is shaped to at least partially define a radially extending airflow for communicating the internal space of the separator element with the outside. The partitioning member according to the present invention is preferably similar in radial dimension to an adjacent ring preform Pieces. That is, the 'separator member preferably has an inner diameter and an outer diameter similar to those of the ring preform. If the knife spacer element is not the same in size as the ring preform, it is preferable to make the separator element slightly smaller (that is, have an inner diameter larger than the ring preform and / or smaller than the ring preform. Outside diameter), rather than the spacers being larger than the ring preform (ie, wider in the radial direction). : In one example of the present invention, the 'separator' element is composed of a carbon material (e.g., graphite or a carbon / carbon composite material) having a peeling layer formed therein. 93555.doc 200538279. In general, the characteristics of the separator element according to the present invention have a clear and fundamental usefulness. Crystal_ μ pieces = using multiple separate spacer element shaped pre-forms between each ring preform in the group. Profiles: Sheets or other unit structures greatly facilitate the loading of stacking rings. Two processing chambers. As noted above, the conventional arrangement described above with respect to Fig. 2 is generally composed of speech / spacer elements. In addition, because of the conventional manual: made of shredded material of the spacer element, such as oxide shaw, it must be broken in a long and tedious manner. Each spacer element is treated with great care during the interval Γ in an attempt to avoid that the elements are also relatively small and thin (e.g., 1Πχ4, χ〇1 which also makes them difficult to handle. ·: Using a single chip according to the present invention Type separator element, arranging the separator element. I: Action instead of placing several separate elements of the separator element according to the conventional method. ^ As compared with loading one of the processing chambers in the conventional manner discussed above or two days later, use this method. The invention's monolithic time is reduced to 2 to 4 hours. The cymbal is loaded on a special basis. In addition, compared with the conventional use of separate spacer elements as shown in FIG. 2, the monolithic separator element according to the present invention The structure preferably supports the weight of one or more ring preforms stacked on the bean in a larger range. In particular, the radial width of the ring-shaped single-piece separator element is approximately equal to or slightly narrower than the width of the ring preform. . Therefore 'the ring preforms have less distortion after being removed from the processing chamber. This means that less remedial machining is required after the densification process to obtain a useful non-deformable surface. As mentioned earlier, the monolithic partition Chip component Has the same directional width as the ring preform about 93555.doc 200538279, or is slightly narrower (for example, 5 mm outside of it). If the single-piece separator element is wider than the ring preform, the second part tends to be self-dense The decomposition gas has residual carbon on which there is residual dithermal decomposition. This will reduce the useful life of the separator elements. In addition to this accumulation, additional repolishing steps are required. In addition, "," Move the knife septum element | outward | extending the outer edge of the ring preform outward, it may result in 'Place several ring preforms in the processing chamber for simultaneous processing (this is usually This will negatively affect the manufacturing efficiency to such a degree and due to the problem of the space in the processing chamber, it is possible to process a small number of laminations in general: Generally, the single-piece separator element according to the present invention is The two surfaces include radially extending channels or other features. Kedao defines the radial inner side and the radial outer side of the connected monolithic separator element with a small part of the net effect library. The milk flow channel. Attention should be paid here. " Partially defined airflow channels, because in some cases, the airflow channels are also partially defined by the opposing surface of the annular preform of the single-piece separator element structure 5. The cross-sectional area of the airflow channel using the single-piece separator ° is better. The net effect can be compared in the previous layout. The area of the cross-section is compared. This consideration can be changed according to individual circumstances. It should be explained that the area of the collective cross-section of the displayed airflow channel can be adjusted (for example, ^) for each channel or similar | ^ inch or ^ for multiple channels or similar. The deciding factor in this regard is to maintain the ideal carrier level for covering the annular preform. ^ The monolithic separator element according to the present invention should be made of a material that can withstand temperatures up to 2 1100 C (preferably up to about 12 00c to 14 0 (rc (for complete purpose)). The selected material is Fortunately, the mentioned operating temperature is the lowest reactivity with the 93555.doc 200538279 preforms. Applicable to :: Examples of materials for sheet separator elements include (but are not limited to, for example, graphite, carbon / carbon and weaving. Carbon fiber yarns; molded ceramic tungsten. "Materials' such as stainless steel, InCC) nel alloys, titanium, molybdenum, buttons, and Figs. 3a-3c, 4a-4r Γ β 5a_5c show that carbon Single thermally conductive graphite. In the latter example, suitable graphite is purchased under the names such as _, UCAR, and MKU-S. According to the present invention, it can be made into a ring shape with P 分 十 j Α carbon / carbon material 3: pref It is possible to densify the carbon fiber fabric layer σ Λ Λ Y CVI or resin impregnation process of woven carbon fiber fabrics ※, 、, or satin layers.: The carbon-based raw materials are molded or known in a known manner. If the graphite is used as the raw material, the required geometry is self-machined in a known manner.

Similarly, the ring-separated please have another correspondingly divided general Regularly shaped raised portions (some indicated by dotted lines such as: not shown) alternate with their relatively lower portions (some indicated by 302b). 93555.doc 10 200538279 / In this example, the raised portions 3 () 2a, 3 ( ) The edge portion of 4a overlaps the edge of the raised portion on the other side of the annular segment piece 300. Example V. They collectively provide a larger weight load area than the conventional spacer element ^ mentioned above. Therefore The weight of the lamination group is spread over a larger area, and it is not necessary to focus in a conventional manner that leads to a relatively serious impact in the conventional method of positioning the conventional spacer element 30. 'Lower part 302b, 304b defines densification Gas can Radially extending channels or airflow channels that flow from the inside of the stacking ring preform to the outside. As mentioned above, 'these channels show a collective cross-sectional area for densified airflow. A boat can vary depending on the operating conditions. G, cross-section The area should generally be comparable to that shown when using the conventional spacer element 30 mentioned above. In Figure __, Figure 4a is a top view of the annular spacer element according to the present invention. Figure 4b is an annular spacer element A perspective view of 4mm. The figure is perpendicular to it: a cross-sectional front view of a ring-shaped separator element 400 flat planar plane separator element 400. The structure of the ring-shaped separator element 400 is similar to that of the ring-shaped separator element _ in that it has a relatively high raised portion on both sides, and 404a alternates with a relatively low portion 4-heart side. Here, the relatively lower part touches, and the side also has the same densified gas that can flow from the radially extending channel or air flow channel of the inner flow portion of the stacked annular preform. Bacheng = Erzhongguang '. The structure of the ring-shaped separator element 30 ° is relative to the thickness boundary of the center plane of the material ^. Therefore, a straight circumferential path can be traced around the outer edge of the annular separator element 300. On the contrary, since the annular spacer element 400 is relatively thinner than the annular spacer element 93555.doc 200538279, there is no considerable planar thickness of the constituent materials therein. Therefore, you can only chase money along the edge of the bad part ㈣ to replace the high and low parts). (See, for example, Figure 4c). … In Figure We, the figure is a top view of the annular separator element according to the present invention. Fig. 5b is a perspective view of the ring-shaped separator element 500. Fig. 5c is a cross-sectional front view of a planar separator element 500, which is perpendicular to the plane in which the annular separator element 5⑻ lies flat. & The most common difference between the ring-shaped separator element and the ring-shaped separator element 3⑽ is that the relatively raised portion 502a, 504 on the opposite side of the ring-shaped separator element 5⑻ is like the lower part, especially see ㈣. As before, the 'lower portions 502b, 504b at least partially define a passage through which the densified gas can pass between the inside and outside t of the stacked ring preform. In one example, it is possible to consider manufacturing a ring-shaped separator element 500 from the viewpoint that corresponding channels 502b, 504b are formed on the opposite side of a carbon (eg, graphite) blank, and the blank has at least a position corresponding to the raised portions 502a, 504a. The initial thickness in the thickness of the annular separator element 500. As mentioned above, the aforementioned geometries can be obtained by any known suitable method, especially but not only by machining or molding or both. When a separator element according to the present invention is manufactured from a carbon material for use in a composite carbon ring preform, sometimes the separator element is followed by the preform after the densification process. To solve this problem, the present invention covers providing a release coating on the separator element table ® to help avoid this. One example of a useful release coating layer includes a first layer composed of Mosh formed on a separator element and a second layer composed of 93555.doc -12-200538279 composed of eighty-two-three formed on the first layer. For example, these layers can be formed using the known area & m Liukou water injection method. The MoSi, layer serves as a bridge layer to improve the structure of the Yahoo layer-it should be noted that a carbon-based splitter is provided. , k ^. The blade spacer has a head outer part during manufacture, especially a graphite-separated K product η & _ ^ piece part. In general, for ring preforms:!: Sheet, and the thermal mass of the graphite separator sheet element to the 仵 ^ Plus® sheet set to promote heating and, in turn, densification. It ’s very beneficial because the temperature of the preform is relatively difficult to rise early. (In the conventional method, the surface and the surface method are used because of the higher exposure to heat than the middle preform in the lamination group. Level). Similarly, 'because of the excellent teaching of the carbon separator element, a more even temperature distribution can be provided across the radial width of adjacent annular preforms. Although the invention has been described in terms of the most practical specific embodiment, special attention should be paid to This is only an example, and appropriate modifications and changes are also possible within the spirit and scope of the scope of the attached patent.
