    • PURPOSE: To provide a crucible made of carbon fiber reinforced carbon composite which is restrained in separation of carbon fiber and deformation while using by reducing machining of a bottom part of the crucible as much as possible after forming the crucible by the filament winding method. CONSTITUTION: The crucible is integrally formed by winding into multi-layers by filament winding method, the carbon fiber is wound such that an inner most 1st layer 2 is made with an orbit passing though a pole O in the bottom 12, a 2nd layer 3 is wound with an orbit passing a 1st hill side of bulging part 6 which is made by the carbon fiber of the 1st layer concentrated to the pole O and forming a bottom of a 1st outer ring 8, each layer successive to 3rd layer 4 is wound with each orbit forming bottom of outer ring passing the hill side of outer surface of inner layer spreading stepwise toward outer side. The heights of tops of bulging parts formed by carbon fiber for multi-layers are almost same.
    • 目的:提供一种由碳纤维增强碳复合材料制成的坩埚,其通过在通过丝缠绕法形成坩埚之后尽可能多地减少坩埚底部的机械加工而使碳纤维分离和变形。 构成:坩埚通过以丝缠绕法缠绕成多层而形成,碳纤维被卷绕,使得最内层的第1层2通过在底部12中通过极O的轨道制成,第2层3 缠绕有通过由第一层的碳纤维制成的凸起部分6的第一山坡集中到极O并形成第一外环8的底部,每层连续到第三层4被卷绕 通过内层外表面的山坡侧的外环的每个轨道形成底部朝向外侧逐渐扩散。 由多层碳纤维形成的凸起部分顶部的高度几乎相同。

    • PURPOSE: A crucible of carbon fiber reinforced carbon composite material for crystal pulling and a method of manufacturing the same are provided to improve resistance to going SiC by impregnating and covering with a pyrolytic carbon on the surface of the C/C composite material. CONSTITUTION: A crucible of carbon fiber reinforced carbon composite material for crystal pulling and a method of manufacturing the same, the crucible being formed using filament windings in a combination of axially reinforced layers as well as circumferential reinforced layers, which combination is given in two or more sets. The circumferential reinforced layers resist a force tending to expand a drum portion of the crucible, and the axially reinforced layers resist a force tending to push down a bottom of the crucible. The axially reinforced layers extending from the bottom to the drum portion can be formed by at least either of a level winding having a contact angle of 0 to 10 degree relative to the central axis or a portal winding, and the circumferential reinforced layers in areas adjacent to the drum portion out of the drum portion and the bottom portion can be formed by at least either of a parallel winding having a contact angle of 70 to 90 degree relative to the central axis or a helical winding. When the axially reinforced layers cover the center of the bottom, an integral crucible of C/C composite material with no hole is provided.
    • 目的:提供用于晶体拉制的碳纤维增强碳复合材料的坩埚及其制造方法,以通过在C / C复合材料的表面上浸渍和覆盖热解碳来改善耐SiC性。 构成:用于晶体拉制的碳纤维增强碳复合材料坩埚及其制造方法,坩埚使用轴向增强层以及周向增强层组合的细丝绕组形成,其组合分为两个或 多套 圆周增强层抵抗倾向于扩大坩埚的鼓部分的力,并且轴向增强层抵抗倾向于压下坩埚底部的力。 从底部延伸到鼓部分的轴向增强层可以由相对于中心轴线或入口绕组具有0至10度的接触角的级联绕组中的至少一个形成,并且邻近的区域中的周向增强层 到鼓部分之外的滚筒部分,并且底部部分可以由相对于中心轴线或螺旋形线圈的接触角为70度至90度的平行绕组中的至少一个形成。 当轴向增强层覆盖底部的中心时,提供了没有孔的C / C复合材料的整体坩埚。
