kammrath-weiss纖維顯微鏡纖維拉伸試驗機外形尺寸為80×100×22立方毫米,這個設備安裝在sem掃描電鏡和光顯微鏡樣品臺上。原位觀察拉伸實驗應用于非常低的載荷,并且有非常高的分辨率(zui小到1×10-5 N)。拉伸速度的范圍是0.1到20微米/秒.我們高剛度的纖維顯微鏡纖維拉伸試驗機,zui小可以非常測量纖維小到2.5µ米直徑,和幾個毫米長度。
Fiber Tensile Module
Tensile Experiments — down to the µN-Range
The outer dimensions of the Fiber Tensile Module are 80 x 100 x 22 mm3, it is mounted to the SEM or light microscope specimen stage "like a large specimen". It allows in-situ observation of tensile testing experiments at extremely low forces, yet very high load resolution (down to 1×10-5 N). The tensile speed range is 0,1 to 20 µm/s. These features, coupled with maximum stiffness of this substage, allow very accurate measurements on fibers of down to 2.5 µm diameter, and several millimeters length. The specimens can be observed statically or dynamically at magnifications well beyond 10 000 x in daily routine work.
The load is measured by the principle of frequency variations on a spring-loaded metal wire. The displacement is taken by a differential transformer (LVDT).
The enlarged view shows the specimen holder, which is a pair of ceramic tubes, ground down to half their diameter (red tips). One side is attached to a parallel sled, driven by a combination of DC-tacho-motor/angular encoder for precise recognition of the displacement. A fine tungsten wire touches the specimen from underneath at 90 degrees. This wire allows heating up the specimen locally.
