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℃。

Biaxial tension mechanism is one kind of important equipment for studyingmechanical model and strength criterion of the carbon/carbon composites.A simpleframe-guide-joint biaxial tension mechanism designed by IMR has been described in thispaper and it is
