中文摘要:
      在CSS电子万能实验机上,采用QBT高低温环境箱实现控温,测试了T300/AG80复合材料试件纵向、横向的高温拉伸性能,其中纵向试件选取的温度范围为室温~375℃,横向试件的温度范围为室温~325℃。采用非接触方式即远程摄像和图像识别相结合的方法,测量了试件在不同温度、不同载荷作用下的变形,并依据变形计算材料纵向、横向的高温弹性模量。获得试件在不同温度下的力学性能保留率,分析了温度对材料性能的影响,进而对材料的高温性能进行评价。
英文摘要:
      Using QBT high-low temperature measurement and control system to control temperature, the longitudinal and latitudinal tensile property of T300/AG80 composite material at high temperature was experimentally investigated on CSS electronic universal testing apparatus, where the longitudinal test specimens were measured from room temperature to 375℃ and the latitudinal test specimens were measured from room temperature to 325℃. Specimen deformations under different loads and at various temperatures were ascertained based on non-contact method, namely remote camera and image recognition. Deformation of longitudinal and latitudinal test specimens were calculated, based on the deformation and loads, elastic modulus was obtained. Retention rate of mechanical properties was calculated at various temperatures and the influence of temperature on material properties was analyzed, then the properties of material at high temperature were evaluated.
