研制的框架、导轨、连杆式双轴拉伸装置,在普通试验机上即可实现双轴拉伸。验证了装置的可靠性,探索了室温和高温下可用的试样形状。碳/碳复合材料室温双轴拉伸结果可靠,高温双轴拉伸温度已接近1300℃。
Developed framework, rails, connecting rod biaxial stretching device, in the ordinary testing machine to achieve biaxial stretching. The reliability of the device was verified and the sample shapes available at room and elevated temperatures were explored. Carbon / carbon composites at room temperature biaxial tensile reliability, high temperature biaxial stretching temperature is close to 1300 ℃.
