Tool for circumferential tensile of silicon carbide composite pipe

The invention relates to the technical field of material detection, and specifically discloses a tool for the circumferential tensile of a silicon carbide composite pipe. The tool comprises an upper half part and a lower half part, which are symmetrically arranged and connected through a positioning pin. The upper half part comprises an integrally formed main body, a fixing shaft, and a semi-annular clamping groove formed in the main body. According to the tool for the circumferential tensile of the silicon carbide composite pipe, the circumferential tensile strength of the silicon carbide composite pipe is measured by using the tool, so that the tool can ensure that both sides of the composite pipe are broken at the same time when stretching, that the strength is close to the true tensilestrength, and that the mechanical property is more stable; and the measurement accuracy is guaranteed. 本发明涉及材料检测技术领域，具体公开了种碳化硅复合材料管环向拉伸工装，包括对称设置且通过定位销相连的上半部分和下半部分，所述的上半部分包括体加工成型的主体和固定轴，以及设于主体上的半环形卡槽。采用本发明装置测量碳化硅复合材料管的环向拉伸强度，
