Hot isostatic pressing sintering mold prefabricated body and manufacturing method thereof
The isostatic pressing sintering mold preform comprises at least six composite carbon layers which are sequentially wound from inside to outside, and each composite carbon layer is provided with a head end and a tail end; wherein tension for eliminating local upheaval exists between the head end and the tail end of the composite carbon layer; interlayer connecting wires for enhancing interlayer connecting force are arranged between every two adjacent composite carbon layers, and the length of at least part of the interlayer connecting wires in the radial direction of the isostatic pressing sintering mold preform is larger than the thickness of at least six composite carbon layers. Local upheaval of the composite carbon layers is eliminated through tension, the problems of virtual stabs and weak interlayer connecting force caused by the local upheaval are avoided, interlayer connecting wires are found, the interlayer connecting force between the composite carbon layers is increased through the interlayer connecting wires, and the problem of layering when the number of layers is increased is avoided.
本发明公开了一种等静压烧结模预制体，包括由内至外依次卷绕设置的至少6层复合碳层，每层所述复合碳层具有首端、尾端；其中，所述复合碳层的首端与尾端之间存在用于消除局部隆起的张力；相邻的两层所述复合碳层之间设置有增强层间连接力的层间连接丝，至少部分所述层间连接丝在所述等静压烧结模预制体径向上的长度大于至少6层复合碳层的厚度。通过张力来消除复合碳层出现的局部隆起，避免局部隆起带来的虚刺、层间连接力较弱的问题，并发现了层间连接丝，通过层间连接丝来增大复合碳层之间的层间连接力，避免在层数增多时出现分层的问题。
