本文对我省某密封材料厂研制的柔性石墨复合材料制品的物理、机械性能指标进行了实验研究,给出了该材料制品的抗压强度极限和密度,用应变电测技术成功地测试了该材料制品的线膨胀系数。为测试非标准试件(石墨复合材料制品)的线膨胀系数寻求了一种新的方法。此方法也可推广应用到测试石墨复合材料及制品的高温、低温和室温下的应力、应变、弹性模量、泊松比等指标。对指导生产实践具有重要意义。
In this paper, the physical and mechanical properties of flexible graphite composite materials developed by a sealing material factory in our province were studied experimentally. The ultimate compressive strength and density of the material were given. The strain gauges were successfully tested The linear expansion coefficient of the material product. A new method has been sought to test the linear expansion coefficient of non-standard test pieces (graphite composite products). This method can also be applied to test graphite composite materials and products of high temperature, low temperature and room temperature stress, strain, elastic modulus, Poisson’s ratio and other indicators. To guide the practice of production of great significance.
